public class MBeanOperationInfo extends MBeanFeatureInfo implements Cloneable
Describes a management operation exposed by an MBean. Instances of
this class are immutable. Subclasses may be mutable but this is
not recommended.

INFO
public static final int INFOIndicates that the operation is read-like: it returns information but does not change any state.- See Also:
- Constant Field Values

MBeanOperationInfo
Constructs anMBeanOperationInfo
object. TheDescriptor
of the constructed object will include fields contributed by any annotations on theMethod
object that contain theDescriptorKey
meta-annotation.- Parameters:
method
- Thejava.lang.reflect.Method
object describing the MBean operation.description
- A human readable description of the operation.
-
MBeanOperationInfo
public MBeanOperationInfo(String name, String description, MBeanParameterInfo[] signature, String type, int impact)Constructs anMBeanOperationInfo
object.- Parameters:
name
- The name of the method.description
- A human readable description of the operation.signature
-MBeanParameterInfo
objects describing the parameters(arguments) of the method. This may be null with the same effect as a zero-length array.type
- The type of the method's return value.impact
- The impact of the method, one ofINFO
,ACTION
,ACTION_INFO
,UNKNOWN
.
-
MBeanOperationInfo
public MBeanOperationInfo(String name, String description, MBeanParameterInfo[] signature, String type, int impact, Descriptor descriptor)Constructs anMBeanOperationInfo
object.- Parameters:
name
- The name of the method.description
- A human readable description of the operation.signature
-MBeanParameterInfo
objects describing the parameters(arguments) of the method. This may be null with the same effect as a zero-length array.type
- The type of the method's return value.impact
- The impact of the method, one ofINFO
,ACTION
,ACTION_INFO
,UNKNOWN
.descriptor
- The descriptor for the operation. This may be null which is equivalent to an empty descriptor.- Throws:
IllegalArgumentException
- ifimpact
is not one of ACTION, ACTION_INFO, INFO or UNKNOWN.- Since:
- 1.6

Method Details
-
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 byObject.clone()
. No deeper cloning of any internal field is made.Since this class is immutable, cloning is chiefly of interest to subclasses.
-
getReturnType
Returns the type of the method's return value.- Returns:
- the return type.
-
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 referencedMBeanParameterInfo
object is not copied.- Returns:
- An array of
MBeanParameterInfo
objects.
-
getImpact
public int getImpact()Returns the impact of the method, one ofINFO, ACTION, ACTION_INFO, UNKNOWN
.- Returns:
- the impact code.
-
equals
Compare this MBeanOperationInfo to another.- Overrides:
equals
in classMBeanFeatureInfo
- Parameters:
o
- the object to compare to.- Returns:
- true if and only if
o
is an MBeanOperationInfo such that itsMBeanFeatureInfo.getName()
,getReturnType()
,MBeanFeatureInfo.getDescription()
,getImpact()
,MBeanFeatureInfo.getDescriptor()
andgetSignature()
values are equal (not necessarily identical) to those of this MBeanConstructorInfo. Two signature arrays are equal if their elements are pairwise equal. - See Also:
