Serialized Fields

anchor

int anchor

This field is used when the component is smaller than its display area. It determines where, within the display area, to place the component.

There are three kinds of possible values: orientation relative, baseline relative and absolute. Orientation relative values are interpreted relative to the container's component orientation property, baseline relative values are interpreted relative to the baseline and absolute values are not. The absolute values are: CENTER, NORTH, NORTHEAST, EAST, SOUTHEAST, SOUTH, SOUTHWEST, WEST, and NORTHWEST. The orientation relative values are: PAGE_START, PAGE_END, LINE_START, LINE_END, FIRST_LINE_START, FIRST_LINE_END, LAST_LINE_START and LAST_LINE_END. The baseline relative values are: BASELINE, BASELINE_LEADING, BASELINE_TRAILING, ABOVE_BASELINE, ABOVE_BASELINE_LEADING, ABOVE_BASELINE_TRAILING, BELOW_BASELINE, BELOW_BASELINE_LEADING, and BELOW_BASELINE_TRAILING. The default value is CENTER.

See Also:

• GridBagConstraints.clone()
• ComponentOrientation

fill

int fill

This field is used when the component's display area is larger than the component's requested size. It determines whether to resize the component, and if so, how.

The following values are valid for fill:

• NONE: Do not resize the component.
• HORIZONTAL: Make the component wide enough to fill its display area horizontally, but do not change its height.
• VERTICAL: Make the component tall enough to fill its display area vertically, but do not change its width.
• BOTH: Make the component fill its display area entirely.

The default value is NONE.

See Also:

• GridBagConstraints.clone()

gridheight

int gridheight

Specifies the number of cells in a column for the component's display area.

Use REMAINDER to specify that the component's display area will be from gridy to the last cell in the column. Use RELATIVE to specify that the component's display area will be from gridy to the next to the last one in its column.

gridheight should be a non-negative value and the default value is 1.

See Also:

• GridBagConstraints.clone()
• GridBagConstraints.gridwidth

gridwidth

int gridwidth

Specifies the number of cells in a row for the component's display area.

Use REMAINDER to specify that the component's display area will be from gridx to the last cell in the row. Use RELATIVE to specify that the component's display area will be from gridx to the next to the last one in its row.

gridwidth should be non-negative and the default value is 1.

See Also:

• GridBagConstraints.clone()
• GridBagConstraints.gridheight

gridx

int gridx

Specifies the cell containing the leading edge of the component's display area, where the first cell in a row has gridx=0. The leading edge of a component's display area is its left edge for a horizontal, left-to-right container and its right edge for a horizontal, right-to-left container. The value RELATIVE specifies that the component be placed immediately following the component that was added to the container just before this component was added.

The default value is RELATIVE. gridx should be a non-negative value.

See Also:

• GridBagConstraints.clone()
• GridBagConstraints.gridy
• ComponentOrientation

gridy

int gridy

Specifies the cell at the top of the component's display area, where the topmost cell has gridy=0. The value RELATIVE specifies that the component be placed just below the component that was added to the container just before this component was added.

The default value is RELATIVE. gridy should be a non-negative value.

See Also:

• GridBagConstraints.clone()
• GridBagConstraints.gridx

insets

Insets insets

This field specifies the external padding of the component, the minimum amount of space between the component and the edges of its display area.

The default value is new Insets(0, 0, 0, 0).

See Also:

• GridBagConstraints.clone()

ipadx

This field specifies the internal padding of the component, how much space to add to the minimum width of the component. The width of the component is at least its minimum width plus ipadx pixels.

The default value is 0.

See Also:

• GridBagConstraints.clone()
• GridBagConstraints.ipady

ipady

int ipady

This field specifies the internal padding, that is, how much space to add to the minimum height of the component. The height of the component is at least its minimum height plus ipady pixels.

The default value is 0.

See Also:

• GridBagConstraints.clone()
• GridBagConstraints.ipadx

Temporary place holder for the Width of the component.

tempX

int tempX

Temporary place holder for the x coordinate.

tempY

int tempY

Temporary place holder for the y coordinate.

weightx

double weightx

Specifies how to distribute extra horizontal space.

The grid bag layout manager calculates the weight of a column to be the maximum weightx of all the components in a column. If the resulting layout is smaller horizontally than the area it needs to fill, the extra space is distributed to each column in proportion to its weight. A column that has a weight of zero receives no extra space.

If all the weights are zero, all the extra space appears between the grids of the cell and the left and right edges.

The default value of this field is 0. weightx should be a non-negative value.

See Also:

• GridBagConstraints.clone()
• GridBagConstraints.weighty

weighty

double weighty

Specifies how to distribute extra vertical space.

The grid bag layout manager calculates the weight of a row to be the maximum weighty of all the components in a row. If the resulting layout is smaller vertically than the area it needs to fill, the extra space is distributed to each row in proportion to its weight. A row that has a weight of zero receives no extra space.

If all the weights are zero, all the extra space appears between the grids of the cell and the top and bottom edges.

The default value of this field is 0. weighty should be a non-negative value.

Class java.awt.SystemColor

class SystemColor extends Color implements Serializable

serialVersionUID:

4503142729533789064L

Serialization Methods

readResolve

private Object readResolve()

The design of the SystemColor class assumes that the SystemColor object instances stored in the static final fields above are the only instances that can be used by developers. This method helps maintain those limits on instantiation by using the index stored in the value field of the serialized form of the object to replace the serialized object with the equivalent static object constant field of SystemColor. See the SystemColor.writeReplace() method for more information on the serialized form of these objects.

writeReplace

private Object writeReplace()
                     throws ObjectStreamException

Returns a specialized version of the SystemColor object for writing to the serialized stream.

Serial Data:

The value field of a serialized SystemColor object contains the array index of the system color instead of the rgb data for the system color. This index is used by the SystemColor.readResolve() method to resolve the deserialized objects back to the original static constant versions to ensure unique instances of each SystemColor object.

Throws:

ObjectStreamException - if a new object replacing this object could not be created

Serialization Methods

readObject

private void readObject(ObjectInputStream s)
                 throws IOException,
ClassNotFoundException

Reads default serializable fields from the stream. Reads from the stream a string and an array of bytes as additional data.

Serial Data:

the String is the name of one of CS_* constants defined in the ColorSpace class if the profile object is a profile for a predefined color space (for example "CS_sRGB"). The string is null otherwise.

The byte[] array is the profile data for the profile. It will usually be null for the predefined profiles.

If the string is recognized as a constant name for predefined color space the object will be resolved into profile obtained with getInstance(int cspace) and the profile data are ignored. Otherwise the object will be resolved into profile obtained with getInstance(byte[] data).

Parameters:

s - stream used for deserialization

Throws:

IOException - thrown by ObjectInputStream

ClassNotFoundException - thrown by ObjectInputStream

NullPointerException - if s is null

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

Writes default serializable fields to the stream. Writes a string and an array of bytes to the stream as additional data.

Serial Data:

the String is the name of one of CS_* constants defined in the ColorSpace class if the profile object is a profile for a predefined color space (for example "CS_sRGB"). The string is null otherwise.

The byte[] array is the profile data for the profile. For predefined color spaces null is written instead of the profile data. If in the future versions of Java API new predefined color spaces will be added, future versions of this class may choose to write for new predefined color spaces not only the color space name, but the profile data as well so that older versions could still deserialize the object.

Parameters:

s - stream used for serialization

Throws:

IOException - thrown by ObjectInputStream

NullPointerException - if s is null

Serialization Methods

readObject

private void readObject(ObjectInputStream s)
                 throws ClassNotFoundException,
IOException

Deserializes this DragGestureEvent. This method first performs default deserialization for all non-transient fields. An attempt is then made to deserialize this object's List of gesture events as well. This is first attempted by deserializing the field events, because, in releases prior to 1.4, a non-transient field of this name stored the List of gesture events. If this fails, the next object in the stream is used instead. If the resulting List is null, this object's List of gesture events is set to an empty List.

Parameters:

s - the ObjectInputStream to read

Throws:

ClassNotFoundException - if the class of a serialized object could not be found

IOException - if an I/O error occurs

Since:

1.4

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

Serializes this DragGestureEvent. Performs default serialization and then writes out this object's List of gesture events if and only if the List can be serialized. If not, null is written instead. In this case, a DragGestureEvent created from the resulting deserialized stream will contain an empty List of gesture events.

Serial Data:

The default serializable fields, in alphabetical order, followed by either a List instance, or null.

Parameters:

s - the ObjectOutputStream to write

Throws:

IOException - if an I/O error occurs

Since:

1.4

Serialization Methods

readObject

private void readObject(ObjectInputStream s)
                 throws ClassNotFoundException,
IOException

Deserializes this DragSource. This method first performs default deserialization. Next, this object's FlavorMap is deserialized by using the next object in the stream. If the resulting FlavorMap is null, this object's FlavorMap is set to the default FlavorMap for this thread's ClassLoader. Next, this object's listeners are deserialized by reading a null-terminated sequence of 0 or more key/value pairs from the stream:

• If a key object is a String equal to dragSourceListenerK, a DragSourceListener is deserialized using the corresponding value object and added to this DragSource.
• If a key object is a String equal to dragSourceMotionListenerK, a DragSourceMotionListener is deserialized using the corresponding value object and added to this DragSource.
• Otherwise, the key/value pair is skipped.

Parameters:

s - the ObjectInputStream to read

Throws:

ClassNotFoundException - if the class of a serialized object could not be found

IOException - if an I/O error occurs

deserialize contents ... if this instance has a distinct peer the children are *not* serialized here, the peer's readObject() must call readChildren() after deserializing this instance.

Parameters:

ois - the ObjectInputStream to read

Throws:

ClassNotFoundException - if the class of a serialized object could not be found

IOException - if an I/O error occurs

writeObject

private void writeObject(ObjectOutputStream oos)
                  throws IOException

Deprecated, for removal: This API element is subject to removal in a future version.

Serialize the BeanContextSupport, if this instance has a distinct peer (that is this object is acting as a delegate for another) then the children of this instance are not serialized here due to a 'chicken and egg' problem that occurs on deserialization of the children at the same time as this instance. Therefore in situations where there is a distinct peer to this instance it should always call writeObject() followed by writeChildren() and readObject() followed by readChildren().

Parameters:

oos - the ObjectOutputStream to write

Throws:

IOException - if an I/O error occurs

Serialization Overview

Class Class is special cased within the Serialization Stream Protocol. A Class instance is written initially into an ObjectOutputStream in the following format:

      TC_CLASS ClassDescriptor
      A ClassDescriptor is a special cased serialization of
      a java.io.ObjectStreamClass instance.
 

A new handle is generated for the initial time the class descriptor is written into the stream. Future references to the class descriptor are written as references to the initial class descriptor instance.

Serialization Methods

readObject

private void readObject(ObjectInputStream s)
                 throws IOException,
ClassNotFoundException

readObject is called to restore the state of the StringBuilder from a stream.

Parameters:

s - the ObjectInputStream from which data is read

Throws:

IOException - if an I/O error occurs

ClassNotFoundException - if a serialized class cannot be loaded

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

Save the state of the StringBuilder instance to a stream (that is, serialize it).

Serial Data:

the number of characters currently stored in the string builder (int), followed by the characters in the string builder (char[]). The length of the char array may be greater than the number of characters currently stored in the string builder, in which case extra characters are ignored.

Parameters:

Serialization Methods

readObject

private void readObject(ObjectInputStream s)
                 throws IOException,
ClassNotFoundException

Reads a Throwable from a stream, enforcing well-formedness constraints on fields. Null entries and self-pointers are not allowed in the list of suppressedExceptions. Null entries are not allowed for stack trace elements. A null stack trace in the serial form results in a zero-length stack element array. A single-element stack trace whose entry is equal to new StackTraceElement("", "", null, Integer.MIN_VALUE) results in a null stackTrace field. Note that there are no constraints on the value the cause field can hold; both null and this are valid values for the field.

Parameters:

s - the ObjectInputStream from which data is read

Throws:

IOException - if an I/O error occurs

ClassNotFoundException - if a serialized class cannot be loaded

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

Write a Throwable object to a stream. A null stack trace field is represented in the serial form as a one-element array whose element is equal to new StackTraceElement("", "", null, Integer.MIN_VALUE).

Parameters:

s - the ObjectOutputStream to which data is written

Throws:

IOException - if an I/O error occurs

Serialized Fields

cause

Throwable cause

The throwable that caused this throwable to get thrown, or null if this throwable was not caused by another throwable, or if the causative throwable is unknown. If this field is equal to this throwable itself, it indicates that the cause of this throwable has not yet been initialized.

Since:

1.4

detailMessage

String detailMessage

Specific details about the Throwable. For example, for FileNotFoundException, this contains the name of the file that could not be found.

stackTrace

StackTraceElement[] stackTrace

The stack trace, as returned by Throwable.getStackTrace(). The field is initialized to a zero-length array. A null value of this field indicates subsequent calls to Throwable.setStackTrace(StackTraceElement[]) and Throwable.fillInStackTrace() will be no-ops.

Since:

1.4

suppressedExceptions

List<Throwable> suppressedExceptions

The list of suppressed exceptions, as returned by Throwable.getSuppressed(). The list is initialized to a zero-element unmodifiable sentinel list. When a serialized Throwable is read in, if the suppressedExceptions field points to a zero-element list, the field is reset to the sentinel value.

Serialization Methods

readObject

private void readObject(ObjectInputStream s)
                 throws IOException,
ClassNotFoundException

Reconstitute the MethodType instance from a stream (that is, deserialize it). This instance is a scratch object with bogus final fields. It provides the parameters to the factory method called by readResolve. After that call it is discarded.

Parameters:

s - the stream to read the object from

Throws:

IOException - if there is a problem reading the object

ClassNotFoundException - if one of the component classes cannot be resolved

See Also:

• MethodType.readResolve()
• MethodType.writeObject(java.io.ObjectOutputStream)

readResolve

private Object readResolve()

Resolves and initializes a MethodType object after serialization.

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

Save the MethodType instance to a stream.

Serial Data:

For portability, the serialized format does not refer to named fields. Instead, the return type and parameter type arrays are written directly from the writeObject method, using two calls to s.writeObject as follows:

s.writeObject(this.returnType());
s.writeObject(this.parameterArray());
 

The deserialized field values are checked as if they were provided to the factory method methodType. For example, null values, or void parameter types, will lead to exceptions during deserialization.

Parameters:

s - the stream to write the object to

Throws:

IOException - if there is a problem writing the object

Serialization Methods

readObject

private void readObject(ObjectInputStream s)
                 throws IOException,
ClassNotFoundException

Reconstitute the BigInteger instance from a stream (that is, deserialize it). The magnitude is read in as an array of bytes for historical reasons, but it is converted to an array of ints and the byte array is discarded. Note: The current convention is to initialize the cache fields, bitCountPlusOne, bitLengthPlusOne and lowestSetBitPlusTwo, to 0 rather than some other marker value. Therefore, no explicit action to set these fields needs to be taken in readObject because those fields already have a 0 value by default since defaultReadObject is not being used.

Parameters:

s - the stream being read.

Throws:

IOException - if an I/O error occurs

ClassNotFoundException - if a serialized class cannot be loaded

readObjectNoData

private void readObjectNoData()
                       throws ObjectStreamException

Serialization without data not supported for this class.

Throws:

ObjectStreamException

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

Save the BigInteger instance to a stream. The magnitude of a BigInteger is serialized as a byte array for historical reasons. To maintain compatibility with older implementations, the integers -1, -1, -2, and -2 are written as the values of the obsolete fields bitCount, bitLength, lowestSetBit, and firstNonzeroByteNum, respectively. These values are compatible with older implementations, but will be ignored by current implementations.

Parameters:

s - the stream to serialize to.

Throws:

IOException - if an I/O error occurs

ObjectStreamException - if a new object replacing this object could not be created

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

WriteObject is called to save the state of the URL to an ObjectOutputStream. The handler is not saved since it is specific to this system.

Serial Data:

the default write object value. When read back in, the reader must ensure that calling getURLStreamHandler with the protocol variable returns a valid URLStreamHandler and throw an IOException if it does not.

Parameters:

s - the ObjectOutputStream to which data is written

Throws:

IOException - if an I/O error occurs

serialVersionUID:

Serialization Methods

readObject

private void readObject(ObjectInputStream in)
                 throws IOException,
ClassNotFoundException

readObject for custom serialization.

This method reads this object's serialized form for this class as follows:

The readUTF method is invoked on in to read the external ref type name for the RemoteRef instance to be filled in to this object's ref field. If the string returned by readUTF has length zero, the readObject method is invoked on in, and than the value returned by readObject is cast to RemoteRef and this object's ref field is set to that value. Otherwise, this object's ref field is set to a RemoteRef instance that is created of an implementation-specific class corresponding to the external ref type name returned by readUTF, and then the readExternal method is invoked on this object's ref field.

If the external ref type name is "UnicastRef", "UnicastServerRef", "UnicastRef2", or "UnicastServerRef2", a corresponding implementation-specific class must be found, and its readExternal method must read the serial data for that external ref type name as specified to be written in the serialData documentation for this class. If the external ref type name is any other string (of non-zero length), a ClassNotFoundException will be thrown, unless the implementation provides an implementation-specific class corresponding to that external ref type name, in which case this object's ref field will be set to an instance of that implementation-specific class.

Parameters:

in - the ObjectInputStream from which data is read

Throws:

IOException - if an I/O error occurs

ClassNotFoundException - if a serialized class cannot be loaded

writeObject

private void writeObject(ObjectOutputStream out)
                  throws IOException

writeObject for custom serialization.

This method writes this object's serialized form for this class as follows:

The getRefClass method is invoked on this object's ref field to obtain its external ref type name. If the value returned by getRefClass was a non-null string of length greater than zero, the writeUTF method is invoked on out with the value returned by getRefClass, and then the writeExternal method is invoked on this object's ref field passing out as the argument; otherwise, the writeUTF method is invoked on out with a zero-length string (""), and then the writeObject method is invoked on out passing this object's ref field as the argument.

Serial Data:

The serialized data for this class comprises a string (written with ObjectOutput.writeUTF) that is either the external ref type name of the contained RemoteRef instance (the ref field) or a zero-length string, followed by either the external form of the ref field as written by its writeExternal method if the string was of non-zero length, or the serialized form of the ref field as written by passing it to the serialization stream's writeObject if the string was of zero length.

If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was returned from any of the UnicastRemoteObject.exportObject methods and custom socket factories are not used, the external ref type name is "UnicastRef". If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was returned from any of the UnicastRemoteObject.exportObject methods and custom socket factories are used, the external ref type name is "UnicastRef2". If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was returned from the RemoteObject.toStub method (and the argument passed to toStub was not itself a RemoteStub), the external ref type name is a function of how the remote object passed to toStub was exported, as described above. If this object is an instance of RemoteStub or RemoteObjectInvocationHandler that was originally created via deserialization, the external ref type name is the same as that which was read when this object was deserialized.

If this object is an instance of java.rmi.server.UnicastRemoteObject that does not use custom socket factories, the external ref type name is "UnicastServerRef". If this object is an instance of UnicastRemoteObject that does use custom socket factories, the external ref type name is "UnicastServerRef2".

Following is the data that must be written by the writeExternal method and read by the readExternal method of RemoteRef implementation classes that correspond to the each of the defined external ref type names:

For "UnicastRef":

• the hostname of the referenced remote object, written by DataOutput.writeUTF(String)
• the port of the referenced remote object, written by DataOutput.writeInt(int)
• the data written as a result of calling ObjID.write(java.io.ObjectOutput) on the ObjID instance contained in the reference
• the boolean value false, written by DataOutput.writeBoolean(boolean)

For "UnicastRef2" with a null client socket factory:

• the byte value 0x00 (indicating null client socket factory), written by DataOutput.writeByte(int)
• the hostname of the referenced remote object, written by DataOutput.writeUTF(String)
• the port of the referenced remote object, written by DataOutput.writeInt(int)
• the data written as a result of calling ObjID.write(java.io.ObjectOutput) on the ObjID instance contained in the reference
• the boolean value false, written by DataOutput.writeBoolean(boolean)

For "UnicastRef2" with a non-null client socket factory:

• the byte value 0x01 (indicating non-null client socket factory), written by DataOutput.writeByte(int)
• the hostname of the referenced remote object, written by DataOutput.writeUTF(String)
• the port of the referenced remote object, written by DataOutput.writeInt(int)
• a client socket factory (object of type java.rmi.server.RMIClientSocketFactory), written by passing it to an invocation of writeObject on the stream instance
• the data written as a result of calling ObjID.write(java.io.ObjectOutput) on the ObjID instance contained in the reference
• the boolean value false, written by DataOutput.writeBoolean(boolean)

For "UnicastServerRef" and "UnicastServerRef2", no data is written by the writeExternal method or read by the readExternal method.

Parameters:

out - the ObjectOutputStream to which data is written

Throws:

IOException - if an I/O error occurs

Serialization Methods

readObject

private void readObject(ObjectInputStream stream)
                 throws IOException,
ClassNotFoundException

Reads the default serializable fields from the stream and performs validations and adjustments for older serialized versions. The validations and adjustments are:

1. Verify that the superclass's digit count fields correctly reflect the limits imposed on formatting numbers other than BigInteger and BigDecimal objects. These limits are stored in the superclass for serialization compatibility with older versions, while the limits for BigInteger and BigDecimal objects are kept in this class. If, in the superclass, the minimum or maximum integer digit count is larger than DOUBLE_INTEGER_DIGITS or if the minimum or maximum fraction digit count is larger than DOUBLE_FRACTION_DIGITS, then the stream data is invalid and this method throws an InvalidObjectException.
2. If serialVersionOnStream is less than 4, initialize roundingMode to RoundingMode.HALF_EVEN. This field is new with version 4.
3. If serialVersionOnStream is less than 3, then call the setters for the minimum and maximum integer and fraction digits with the values of the corresponding superclass getters to initialize the fields in this class. The fields in this class are new with version 3.
4. If serialVersionOnStream is less than 1, indicating that the stream was written by JDK 1.1, initialize useExponentialNotation to false, since it was not present in JDK 1.1.
5. Set serialVersionOnStream to the maximum allowed value so that default serialization will work properly if this object is streamed out again.

Stream versions older than 2 will not have the affix pattern variables posPrefixPattern etc. As a result, they will be initialized to null, which means the affix strings will be taken as literal values. This is exactly what we want, since that corresponds to the pre-version-2 behavior.

Serialization Methods

readExternal

public void readExternal(ObjectInput in)
                  throws IOException,
ClassNotFoundException

Implements the Externalizable interface to read the object.

Serial Data:

The streamed type and parameters defined by the type's writeReplace method are read and passed to the corresponding static factory for the type to create a new instance. That instance is returned as the de-serialized Ser object.

• ZoneRules - ZoneRules.of(standardTransitions, standardOffsets, savingsInstantTransitions, wallOffsets, lastRules);
• ZoneOffsetTransition - ZoneOffsetTransition of(LocalDateTime.ofEpochSecond(epochSecond), offsetBefore, offsetAfter);
• ZoneOffsetTransitionRule - ZoneOffsetTransitionRule.of(month, dom, dow, time, timeEndOfDay, timeDefinition, standardOffset, offsetBefore, offsetAfter);

Parameters:

in - the data to read, not null

Throws:

IOException - if I/O errors occur

ClassNotFoundException - If the class for an object being restored cannot be found.

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Implements the Externalizable interface to write the object.

Serial Data:

Each serializable class is mapped to a type that is the first byte in the stream. Refer to each class writeReplace serialized form for the value of the type and sequence of values for the type.

• ZoneRules.writeReplace
• ZoneOffsetTransition.writeReplace
• ZoneOffsetTransitionRule.writeReplace

Parameters:

out - the data stream to write to, not null

Throws:

IOException - Includes any I/O exceptions that may occur

Class java.time.zone.ZoneOffsetTransition

Serialization Methods

readObject

private void readObject(ObjectInputStream s)
                 throws InvalidObjectException

Defend against malicious streams.

Parameters:

s - the stream to read

Throws:

InvalidObjectException - always

writeReplace

private Object writeReplace()

Writes the object using a dedicated serialized form.

Serial Data:

Refer to the serialized form of ZoneRules.writeReplace for the encoding of epoch seconds and offsets.

   out.writeByte(2);                // identifies a ZoneOffsetTransition
   out.writeEpochSec(toEpochSecond);
   out.writeOffset(offsetBefore);
   out.writeOffset(offsetAfter);
 
 

Serialized Fields

epochSecond

long epochSecond

The transition epoch-second.

offsetAfter

ZoneOffset offsetAfter

The offset after transition.

offsetBefore

ZoneOffset offsetBefore

The offset before transition.

transition

LocalDateTime transition

The local transition date-time at the transition.
