instance.getReturnOpenType in interface OpenMBeanOperationInfopublic 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 in interface OpenMBeanOperationInfoequals in class MBeanOperationInfoobj - the object to be compared for equality with this
OpenMBeanOperationInfoSupport instance;true if the specified object is equal to this
OpenMBeanOperationInfoSupport instance.Object.hashCode(),
HashMappublic 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.

System.identityHashCode(java.lang.Object)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.
