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 
 

Note: because of inconsistencies in previous versions of this specification, it is recommended not to use negative or zero values for currencyTimeLimit. To indicate that a cached value is never valid, omit the currencyTimeLimit field. To indicate that it is always valid, use a very large number for this field.

ModelMBeanOperationInfo

public ModelMBeanOperationInfo(String description,
                               Method operationMethod)

Constructs a ModelMBeanOperationInfo object with a default descriptor. The Descriptor of the constructed object will include fields contributed by any annotations on the Method object that contain the DescriptorKey meta-annotation.

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. The Descriptor of the constructed object will include fields contributed by any annotations on the Method object that contain the DescriptorKey meta-annotation.

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 optional field "role" is not equal to "operation", "getter", or "setter".

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.

ModelMBeanOperationInfo

public ModelMBeanOperationInfo(ModelMBeanOperationInfo inInfo)

Constructs a new ModelMBeanOperationInfo object from this ModelMBeanOperation Object.

Parameters:

inInfo - the ModelMBeanOperationInfo to be duplicated

clone

public Object clone()

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

Overrides:

clone in class MBeanOperationInfo

Returns:

a clone of this instance.

Cloneable

getDescriptor

public Descriptor getDescriptor()

Returns a copy of the associated Descriptor of the ModelMBeanOperationInfo.

Specified by:

getDescriptor in interface DescriptorRead

Overrides:

getDescriptor in class MBeanFeatureInfo

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.

Throws:

RuntimeOperationsException - Wraps an IllegalArgumentException for invalid Descriptor.

toString

public String toString()

Returns a string containing the entire contents of the ModelMBeanOperationInfo in human readable form.

Overrides:

toString in class MBeanOperationInfo

Returns:

a string representation of the object.
