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.
ModelMBeanOperationInfo Fields
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.
