 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.- Since:

Constructor Detail- 
MBeanOperationInfopublic MBeanOperationInfo(String description, Method method) Constructs anMBeanOperationInfoobject. TheDescriptorof the constructed object will include fields contributed by any annotations on theMethodobject that contain theDescriptorKeymeta-annotation.- Parameters:
- method- The- java.lang.reflect.Methodobject describing the MBean operation.
- description- A human readable description of the operation.
 
 - 
MBeanOperationInfopublic MBeanOperationInfo(String name, String description, MBeanParameterInfo[] signature, String type, int impact) Constructs anMBeanOperationInfoobject.- Parameters:
- name- The name of the method.
- description- A human readable description of the operation.
- signature-- MBeanParameterInfoobjects 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 of- INFO,- ACTION,- ACTION_INFO,- UNKNOWN.

MBeanOperationInfopublic MBeanOperationInfo(String name, String description, MBeanParameterInfo[] signature, String type, int impact, Descriptor descriptor) Constructs anMBeanOperationInfoobject.- Parameters:
- name- The name of the method.
- description- A human readable description of the operation.
- signature-- MBeanParameterInfoobjects 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 of- INFO,- ACTION,- ACTION_INFO,- UNKNOWN.
- descriptor- The descriptor for the operation. This may be null which is equivalent to an empty descriptor.
- Throws:
- IllegalArgumentException- if- impactis not one of ACTION, ACTION_INFO, INFO or UNKNOWN.

Method Detail- 
clonepublic 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 byObject.clone(). No deeper cloning of any internal field is made.Since this class is immutable, cloning is chiefly of interest to subclasses. 
 - 
getReturnTypepublic String getReturnType() Returns the type of the method's return value.- Returns:
- the return type.
 
 - 
getSignaturepublic MBeanParameterInfo[] getSignature() Returns the list of parameters for this operation. Each parameter is described by an MBeanParameterInfoobject.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 MBeanParameterInfoobjects but that each referencedMBeanParameterInfoobject is not copied.- Returns:
- An array of MBeanParameterInfoobjects.
 
 - 
getImpactpublic int getImpact() Returns the impact of the method, one ofINFO, ACTION, ACTION_INFO, UNKNOWN.- Returns:
- the impact code.
 
 - 
equalspublic boolean equals(Object o) Compare this MBeanOperationInfo to another.- Overrides:
- equalsin class- MBeanFeatureInfo
- Parameters:
- o- the object to compare to.
- Returns:
- true if and only if ois 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.
