java.lang.Objectjavax.management.JMX.MBeanOptions
public static class JMX.MBeanOptions extends Object implements Serializable, Cloneable
Options to apply to an MBean proxy or to an instance of StandardMBean.
For example, to specify the "wrapped object visible" option for a
StandardMBean, you might write this:
StandardMBean.Options opts = new StandardMBean.Options(); opts.setWrappedObjectVisible(true); StandardMBean mbean = new StandardMBean(impl, intf, opts);

public JMX.MBeanOptions clone()
Objectx, the expression:
will be true, and that the expression:x.clone() != x
will bex.clone().getClass() == x.getClass()
true, but these are not absolute requirements.
While it is typically the case that:
will bex.clone().equals(x)
true, this is not an absolute requirement.
By convention, the returned object should be obtained by calling
super.clone. If a class and all of its superclasses (except
Object) obey this convention, it will be the case that
x.clone().getClass() == x.getClass().
By convention, the object returned by this method should be independent
of this object (which is being cloned). To achieve this independence,
it may be necessary to modify one or more fields of the object returned
by super.clone before returning it. Typically, this means
copying any mutable objects that comprise the internal "deep structure"
of the object being cloned and replacing the references to these
objects with references to the copies. If a class contains only
primitive fields or references to immutable objects, then it is usually
the case that no fields in the object returned by super.clone
need to be modified.
The method clone for class Object performs a
specific cloning operation. First, if the class of this object does
not implement the interface Cloneable, then a
CloneNotSupportedException is thrown. Note that all arrays
are considered to implement the interface Cloneable.
Otherwise, this method creates a new instance of the class of this
object and initializes all its fields with exactly the contents of
the corresponding fields of this object, as if by assignment; the
contents of the fields are not themselves cloned. Thus, this method
performs a "shallow copy" of this object, not a "deep copy" operation.
The class Object does not itself implement the interface
Cloneable, so calling the clone method on an object
whose class is Object will result in throwing an
exception at run time.
clone in class ObjectCloneablepublic boolean isMXBean()
True if this is an MXBean proxy or a StandardMBean instance that is an MXBean. The default value is false.
This method is equivalent to this.getMXBeanMappingFactory()!= null.
public MXBeanMappingFactory getMXBeanMappingFactory()
The mappings between Java types and Open Types to be used in an MXBean proxy or a StandardMBean instance that is an MXBean, or null if this instance is not for an MXBean. The default value is null.
public void setMXBeanMappingFactory(MXBeanMappingFactory f)
Set the MXBeanMappingFactory to
the given value. The value should be null if this instance is not
for an MXBean. If this instance is for an MXBean, the value should
usually be either a custom mapping factory, or
MXBeanMappingFactory.forInterface(mxbeanInterface)
which signifies
that the default mapping
factory should be used unless an @MXBeanMappingFactoryClass annotation on mxbeanInterface
specifies otherwise.
Examples:
MBeanOptions opts = new MBeanOptions();
opts.setMXBeanMappingFactory(myMappingFactory);
MyMXBean proxy = JMX.newMBeanProxy(
mbeanServerConnection, objectName, MyMXBean.class, opts);
// ...or...
MBeanOptions opts = new MBeanOptions();
MXBeanMappingFactory defaultFactoryForMyMXBean =
MXBeanMappingFactory.forInterface(MyMXBean.class);
opts.setMXBeanMappingFactory(defaultFactoryForMyMXBean);
MyMXBean proxy = JMX.newMBeanProxy(
mbeanServerConnection, objectName, MyMXBean.class, opts);

MXBean.public String toString()
ObjecttoString method returns a string that
"textually represents" this object. The result should
be a concise but informative representation that is easy for a
person to read.
It is recommended that all subclasses override this method.
The toString method for class Object
returns a string consisting of the name of the class of which the
object is an instance, the at-sign character `@', and
the unsigned hexadecimal representation of the hash code of the
object. In other words, this method returns a string equal to the
value of:
getClass().getName() + '@' + Integer.toHexString(hashCode())
toString in class Objectpublic boolean equals(Object obj)
Indicates whether some other object is "equal to" this one. The result is true if and only if the other object is also an instance of MBeanOptions or a subclass, and has the same properties with the same values.

The general contract of hashCode is:
hashCode method
must consistently return the same integer, provided no information
used in equals comparisons on the object is modified.
This integer need not remain consistent from one execution of an
application to another execution of the same application.
equals(Object)
method, then calling the hashCode method on each of
the two objects must produce the same integer result.
Object.equals(java.lang.Object)
method, then calling the hashCode method on each of the
two objects must produce distinct integer results. However, the
programmer should be aware that producing distinct integer results
for unequal objects may improve the performance of hash tables.
As much as is reasonably practical, the hashCode method defined by
class Object does return distinct integers for distinct
objects. (This is typically implemented by converting the internal
address of the object into an integer, but this implementation
technique is not required by the
JavaTM programming language.)
