public class MBeanOperationInfo extends MBeanFeatureInfo implements Cloneable
Modifier and Type | Field | Description |
---|---|---|
static int |
ACTION |
Indicates that the operation is write-like: it has an effect but does
not return any information from the MBean.
|
static int |
ACTION_INFO |
Indicates that the operation is both read-like and write-like:
it has an effect, and it also returns information from the MBean.
|
static int |
INFO |
Indicates that the operation is read-like:
it returns information but does not change any state.
|
static int |
UNKNOWN |
Indicates that the impact of the operation is unknown or cannot be
expressed using one of the other values.

.descriptor
- The descriptor for the operation. This may be null
which is equivalent to an empty descriptor.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, cloning is chiefly of interest to subclasses.
public String getReturnType()
public MBeanParameterInfo[] getSignature()
Returns the list of parameters for this operation. Each
parameter is described by an MBeanParameterInfo
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 MBeanParameterInfo
objects but
that each referenced MBeanParameterInfo
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())

that its MBeanFeatureInfo.getName()
, getReturnType()
, MBeanFeatureInfo.getDescription()
, getImpact()

values are equal (not necessarily identical)
to those of this MBeanConstructorInfo. Two signature arrays
are equal if their elements are pairwise equal.Object.hashCode()

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. (The hashCode may or may not be implemented
as some function of an object's memory address at some point
in time.)
