## javax.management.modelmbean
Class ModelMBeanOperationInfo

    java.lang.Object
      javax.management.MBeanFeatureInfo
          javax.management.MBeanOperationInfo
              javax.management.modelmbean.ModelMBeanOperationInfo

All Implemented Interfaces:
  Serializable, Cloneable, DescriptorAccess

    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.

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.

  1.5

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".

### 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.

### ModelMBeanOperationInfo
