* This class is a utility class that transform SNMP GET / SET requests * into series of getAttributeName() setAttributeName() * invoked on the MBean. *
* *
* 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 mibgen.
*
* The MBean is not invoked directly by this class but through the * metadata object which holds a reference on it. *
* ** This class is used internally by mibgen generated metadata objects and * you should never need to use it directly. *
*This API is a Sun Microsystems internal API and is subject * to change without notice.
