|
* invoked on the MBean. |
|
* </p> |
|
* |
|
* <p> |
|
* The transformation relies on the metadata information provided by the |
|
* {@link com.sun.jmx.snmp.agent.SnmpStandardMetaServer} object which is |
|
* passed as first parameter to every method. This SnmpStandardMetaServer |
|
* object is usually a Metadata object generated by <code>mibgen</code>. |
|
* </p> |
|
* |
|
* <p> |
|
* The MBean is not invoked directly by this class but through the |
|
* metadata object which holds a reference on it. |
|
* </p> |
|
* |
|
* <p><b><i> |
|
* This class is used internally by mibgen generated metadata objects and |
|
* you should never need to use it directly. |
