public interface OpenMBeanOperationInfo
Describes an operation of an Open MBean.
This interface declares the same methods as the class MBeanOperationInfo
. A class implementing this interface (typically OpenMBeanOperationInfoSupport
) should extend MBeanOperationInfo
.
The getSignature()
method should return at runtime an array of instances of a subclass of MBeanParameterInfo
which implements the OpenMBeanParameterInfo
interface (typically OpenMBeanParameterInfoSupport
).
String getDescription()
Returns a human readable description of the operation described by this OpenMBeanOperationInfo
instance.
String getName()
Returns the name of the operation described by this OpenMBeanOperationInfo
instance.
MBeanParameterInfo[] getSignature()
Returns an array of OpenMBeanParameterInfo
instances describing each parameter in the signature of the operation described by this OpenMBeanOperationInfo
instance. Each instance in the returned array should actually be a subclass of MBeanParameterInfo
which implements the OpenMBeanParameterInfo
interface (typically OpenMBeanParameterInfoSupport
).
int getImpact()
Returns an int
constant qualifying the impact of the operation described by this OpenMBeanOperationInfo
instance. The returned constant is one of MBeanOperationInfo.INFO
, MBeanOperationInfo.ACTION
, MBeanOperationInfo.ACTION_INFO
, or MBeanOperationInfo.UNKNOWN
.
String getReturnType()
Returns the fully qualified Java class name of the values returned by the operation described by this OpenMBeanOperationInfo
instance. This method should return the same value as a call to getReturnOpenType().getClassName()
.
OpenType<?> getReturnOpenType()
Returns the open type of the values returned by the operation described by this OpenMBeanOperationInfo
instance.
boolean equals(Object obj)
Compares the specified obj parameter with this OpenMBeanOperationInfo
instance for equality.
Returns true
if and only if all of the following statements are true:
OpenMBeanOperationInfo
interface,equals
method works properly for obj parameters which are different implementations of the OpenMBeanOperationInfo
interface. equals
in class Object
obj
- the object to be compared for equality with this OpenMBeanOperationInfo
instance;true
if the specified object is equal to this OpenMBeanOperationInfo
instance.Object.hashCode()
, HashMap
int hashCode()
Returns the hash code value for this OpenMBeanOperationInfo
instance.
The hash code of an OpenMBeanOperationInfo
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 OpenMBeanOperationInfo
instances t1
and t2
, as required by the general contract of the method Object.hashCode()
.

String toString()
Returns a string representation of this OpenMBeanOperationInfo
instance.
The string representation consists of the name of this class (ie javax.management.openmbean.OpenMBeanOperationInfo
), and the name, signature, return open type and impact of the described operation.
