## Class ModelMBeanOperationInfo

- java.lang.Object
- - javax.management.MBeanFeatureInfo
  - - javax.management.MBeanOperationInfo
    - - 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. Note that when the Type in this table is Number, a String that is the decimal representation of a Long can also be used.

  Name | Type | Meaning
  --- | --- | ---
  name | String | Operation name.
  descriptorType | String | Must be "operation".
  class | String | Class where method is defined (fully qualified).
  role | String | Must be "operation", "getter", or "setter".
  targetObject | Object | Object on which to execute this method.
  targetType | String | type of object reference for targetObject. Can be: ObjectReference | Handle | EJBHandle | IOR | RMIReference.
  value | Object | Cached value for operation.
  displayName | String | Human readable display name of the operation.
  currencyTimeLimit | Number | How long cached value is valid.
  lastUpdatedTimeStamp | Number | When cached value was set.
  visibility | Number | 1-4 where 1: always visible 4: rarely visible.
  presentationString | String | 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`.

    - #### 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", the missing ones are added 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 present but not equal to "operation", "getter", or "setter".
