Nested Class Summary

Nested classes/interfaces declared in class Enum

Enum.EnumDesc<E>

Modifier and Type	Class	Description
static final class	Enum.EnumDesc<E extends Enum<E>>	A nominal descriptor for an enum constant.

Enum Constant Summary

Enum Constants

Enum Constant	Description

Method Summary

Modifier and Type	Method	Description
static StackWalker.Option	valueOf(String name)	Returns the enum constant of this class with the specified name.

Methods declared in class Enum

clone, compareTo, describeConstable, equals, finalize, getDeclaringClass, hashCode, name, ordinal, toString, valueOf

Modifier and Type	Method	Description
protected final Object	clone()	Throws CloneNotSupportedException.
final int	compareTo(StackWalker.Option o)	Compares this enum with the specified object for order.
final Optional<Enum.EnumDesc<StackWalker.Option>>	describeConstable()	Returns an enum descriptor EnumDesc for this instance, if one can be constructed, or an empty Optional if one cannot be.
final boolean	equals(Object other)	Returns true if the specified object is equal to this enum constant.
protected final void	finalize()	Deprecated, for removal: This API element is subject to removal in a future version. Finalization has been deprecated for removal.
final Class<StackWalker.Option>	getDeclaringClass()	Returns the Class object corresponding to this enum constant's enum type.
final int	hashCode()	Returns a hash code for this enum constant.
final String	name()	Returns the name of this enum constant, exactly as declared in its enum declaration.
final int	ordinal()	Returns the ordinal of this enumeration constant (its position in its enum declaration, where the initial constant is assigned an ordinal of zero).
String	toString()	Returns the name of this enum constant, as contained in the declaration.
static <T extends Enum<T>> T	valueOf(Class<T> enumClass, String name)	Returns the enum constant of the specified enum class with the specified name.

Methods declared in class Object

getClass, notify, notifyAll, wait, wait, wait

Modifier and Type	Method	Description
final Class<?>	getClass()	Returns the runtime class of this Object.
final void	notify()	Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll()	Wakes up all threads that are waiting on this object's monitor.
final void	wait()	Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
final void	wait(long timeoutMillis)	Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
final void	wait(long timeoutMillis, int nanos)	Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

Enum Constant Details

RETAIN_CLASS_REFERENCE

public static final StackWalker.Option RETAIN_CLASS_REFERENCE

Retains Class object in StackFrames walked by this StackWalker.

A StackWalker configured with this option will support StackWalker.getCallerClass() and StackFrame.getDeclaringClass().

DROP_METHOD_INFO

public static final StackWalker.Option DROP_METHOD_INFO

Drops the method information from StackFrames walked by this StackWalker.

A StackWalker configured with this option will drop the method name, the method type, the line number, the bytecode index, the source file name and native method or not.

Since:

22

SHOW_REFLECT_FRAMES

public static final StackWalker.Option SHOW_REFLECT_FRAMES

Shows all reflection frames.

By default, reflection frames are hidden. A StackWalker configured with this SHOW_REFLECT_FRAMES option will show all reflection frames that include Method.invoke(Object, Object...) and Constructor.newInstance(Object...) and their reflection implementation classes.

The SHOW_HIDDEN_FRAMES option can also be used to show all reflection frames and it will also show other hidden frames that are implementation-specific.

API Note:

This option includes the stack frames representing the invocation of Method and Constructor. Any utility methods that are equivalent to calling Method.invoke or Constructor.newInstance such as Class.newInstance are not filtered or controlled by any stack walking option.

SHOW_HIDDEN_FRAMES

public static final StackWalker.Option SHOW_HIDDEN_FRAMES

Shows all hidden frames.

A Java Virtual Machine implementation may hide implementation specific frames in addition to reflection frames. A StackWalker with this SHOW_HIDDEN_FRAMES option will show all hidden frames (including reflection frames).

Method Details

values

public static StackWalker.Option[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static StackWalker.Option valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
