public class ModelMBeanOperationInfo

extends MBeanOperationInfo

implements DescriptorAccess

The ModelMBeanOperationInfo object describes a management operation of the ModelMBean. It is a subclass of MBeanOperationInfo with the addition of an associated Descriptor and an implementation of the DescriptorAccess interface.

 The fields in the descriptor are defined, but not limited to, the following: 
 name           : operation name 
 descriptorType : must be "operation"    
 class          : class where method is defined (fully qualified) 
 role           : must be "operation", "getter", or "setter
 targetObject   : object on which to execute this method          
 targetType     : type of object reference for targetObject. Can be: ObjectReference | Handle | EJBHandle | IOR | RMIReference.
 value          : cached value for operation                   
 currencyTimeLimit : how long cached value is valid               
 lastUpdatedTimeStamp : when cached value was set                
 visibility            : 1-4 where 1: always visible 4: rarely visible 
 presentationString :  xml formatted string to describe how to present operation 
 

The default descriptor will have name, descriptorType, displayName and role fields set.

Constructor Detail

ModelMBeanOperationInfo

public ModelMBeanOperationInfo(String description,
                               Method operationMethod)

Constructs a ModelMBeanOperationInfo object with a default descriptor.

Parameters:

operationMethod - The java.lang.reflect.Method object describing the MBean operation.

description - A human readable description of the operation.

---

ModelMBeanOperationInfo

public ModelMBeanOperationInfo(String description,
                               Method operationMethod,
                               Descriptor descriptor)

Constructs a ModelMBeanOperationInfo object.

Parameters:

operationMethod - The java.lang.reflect.Method object describing the MBean operation.

description - A human readable description of the operation.

descriptor - An instance of Descriptor containing the appropriate metadata for this instance of the ModelMBeanOperationInfo. If it is null a default descriptor will be created. If the descriptor does not contain the fields "displayName" or "role" these fields are added in the descriptor with their default values.

Throws:

RuntimeOperationsException - Wraps an IllegalArgumentException. The descriptor is invalid, or descriptor field "name" is not equal to operation name, or descriptor field "DescriptorType" is not equal to "operation", or descriptor field "role" is not equal to "operation".

                               String type,
                               int impact)

Constructs a ModelMBeanOperationInfo object with a default descriptor.

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.

type - The type of the method's return value.

impact - The impact of the method, one of INFO, ACTION, ACTION_INFO, UNKNOWN.

---

ModelMBeanOperationInfo

public ModelMBeanOperationInfo(ModelMBeanOperationInfo inInfo)

Constructs a new ModelMBeanOperationInfo object from this ModelMBeanOperation Object.

Parameters:

inInfo - the ModelMBeanOperationInfo to be duplicated

Method Detail

clone

public Object clone()

Creates and returns a new ModelMBeanOperationInfo which is a duplicate of this ModelMBeanOperationInfo.

Overrides:

clone in class MBeanOperationInfo

---

getDescriptor

public Descriptor getDescriptor()

Returns a copy of the associated Descriptor of the ModelMBeanOperationInfo.

Specified by:

getDescriptor in interface DescriptorAccess

Returns:

Descriptor associated with the ModelMBeanOperationInfo object.

See Also:

setDescriptor(javax.management.Descriptor)

---

setDescriptor

public void setDescriptor(Descriptor inDescriptor)

Sets associated Descriptor (full replace) for the ModelMBeanOperationInfo If the new Descriptor is null, then the associated Descriptor reverts to a default descriptor. The Descriptor is validated before it is assigned. If the new Descriptor is invalid, then a RuntimeOperationsException wrapping an IllegalArgumentException is thrown.

Specified by:

setDescriptor in interface DescriptorAccess

Parameters:

inDescriptor - replaces the Descriptor associated with the ModelMBeanOperation.
