Class ModelMBeanOperationInfo

java.lang.Object
  extended by javax.management.MBeanFeatureInfo
      extended by javax.management.MBeanOperationInfo
          extended by javax.management.modelmbean.ModelMBeanOperationInfo
All Implemented Interfaces:
Serializable, Cloneable, DescriptorAccess, DescriptorRead

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. The default value of the name and displayName fields is the operation name.

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.

The serialVersionUID of this class is 6532732096650090465L.

Constructor Detail

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 all the fields "name", "descriptorType", "displayName", and "role", the missing ones are added with their default values.
Throws:
RuntimeOperationsException - Wraps an IllegalArgumentException. The descriptor is invalid; or descriptor field "name" is present but not equal to operation name; or descriptor field "DescriptorType" is present but not equal to "operation"; or descriptor optional field "role" is not equal to "operation", "getter", or "setter".

ModelMBeanOperationInfo

public ModelMBeanOperationInfo(String name,
                               String description,
                               MBeanParameterInfo[] signature,
                               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.
