public boolean equals(Object obj)
Compares the specified obj
parameter with this
OpenMBeanOperationInfoSupport
instance for
equality.
Returns true
if and only if all of the following
statements are true:
obj
is non null,obj
also implements the OpenMBeanOperationInfo
interface,equals
method works properly for
obj
parameters which are different implementations of
the OpenMBeanOperationInfo
interface.equals

instance.Object.hashCode()
,
HashMap
public int hashCode()
Returns the hash code value for this OpenMBeanOperationInfoSupport
instance.
The hash code of an OpenMBeanOperationInfoSupport
instance is the sum of the hash codes of all elements of
information used in equals
comparisons (ie: its name,
return open type, impact and signature, where the signature
hashCode is calculated by a call to java.util.Arrays.asList(this.getSignature).hashCode()
).
This ensures that t1.equals(t2)
implies that t1.hashCode()==t2.hashCode()
for any two OpenMBeanOperationInfoSupport
instances t1
and t2
, as required by the general contract of the method Object.hashCode()
.
However, note that another instance of a class implementing
the OpenMBeanOperationInfo
interface may be equal to
this OpenMBeanOperationInfoSupport
instance as defined
by equals(java.lang.Object)
, but may have a different
hash code if it is calculated differently.
As OpenMBeanOperationInfoSupport
instances are
immutable, the hash code for this instance is calculated once,
on the first call to hashCode
, and then the same value
is returned for subsequent calls.

public String toString()
Returns a string representation of this OpenMBeanOperationInfoSupport
instance.
The string representation consists of the name of this class
(ie javax.management.openmbean.OpenMBeanOperationInfoSupport
), and
the name, signature, return open type and impact of the
described operation and the string representation of its descriptor.
As OpenMBeanOperationInfoSupport
instances are
immutable, the string representation for this instance is
calculated once, on the first call to toString
, and
then the same value is returned for subsequent calls.
