public Object clone()
Returns a shallow clone of this instance. The clone is obtained by simply calling super.clone(), thus calling the default native shallow cloning mechanism implemented by Object.clone(). No deeper cloning of any internal field is made.
Since this class is immutable, the clone method is chiefly of interest to subclasses.
Cloneable
public String getClassName()
MBeanInfo
.
public String getDescription()
public MBeanAttributeInfo[] getAttributes()
MBeanAttributeInfo
object.
The returned array is a shallow copy of the internal array,
which means that it is a copy of the internal array of
references to the MBeanAttributeInfo
objects
but that each referenced MBeanAttributeInfo
object is not copied.
MBeanAttributeInfo
objects.public MBeanOperationInfo[] getOperations()
MBeanOperationInfo
object.
The returned array is a shallow copy of the internal array,
which means that it is a copy of the internal array of
references to the MBeanOperationInfo
objects
but that each referenced MBeanOperationInfo
object is not copied.
MBeanOperationInfo
objects.public MBeanConstructorInfo[] getConstructors()
Returns the list of the public constructors of the MBean.
Each constructor is described by an
MBeanConstructorInfo
object.
The returned array is a shallow copy of the internal array,
which means that it is a copy of the internal array of
references to the MBeanConstructorInfo
objects but
that each referenced MBeanConstructorInfo
object
is not copied.
The returned list is not necessarily exhaustive. That is, the MBean may have a public constructor that is not in the list. In this case, the MBean server can construct another instance of this MBean's class using that constructor, even though it is not listed here.
MBeanConstructorInfo
objects.public MBeanNotificationInfo[] getNotifications()
MBeanNotificationInfo
object.
The returned array is a shallow copy of the internal array,
which means that it is a copy of the internal array of
references to the MBeanNotificationInfo
objects
but that each referenced MBeanNotificationInfo
object is not copied.

public String toString()
Object
toString
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())
public boolean equals(Object o)
Compare this MBeanInfo to another. Two MBeanInfo objects
are equal if and only if they return equal values for getClassName()
, for getDescription()
, and for
getDescriptor()
, and the
arrays returned by the two objects for getAttributes()
, getOperations()
, getConstructors()
, and getNotifications()
are
pairwise equal. Here "equal" means Object.equals(Object)
, not identity.
If two MBeanInfo objects return the same values in one of their arrays but in a different order then they are not equal.
o
- the object to compare to.
o
is an MBeanInfo that is equal
to this one according to the rules above.Object.hashCode()

Hashtable
public int hashCode()
Object
java.util.Hashtable
.
The general contract of hashCode
is:
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 hashtables.
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.)
