This object makes it possible to remotelly trigger the Garbage Collector in the JVM. This object's syntax is an enumeration which defines: * Two state values, that can be returned from a GET request: unsupported(1): means that remote invocation of gc() is not supported by the SNMP agent. supported(2) : means that remote invocation of gc() is supported by the SNMP agent. * One action value, that can be provided in a SET request to trigger the garbage collector: start(3) : means that a manager wishes to trigger garbage collection. * Two result value, that will be returned in the response to a SET request when remote invocation of gc is supported by the SNMP agent: started(4) : means that garbage collection was successfully triggered. It does not mean however that the action was successfullly completed: gc might still be running when this value is returned. failed(5) : means that garbage collection couldn't be triggered. * If remote invocation is not supported by the SNMP agent, then unsupported(1) will always be returned as a result of either a GET request, or a SET request with start(3) as input value. * If a SET request with anything but start(3) is received, then the agent will return a wrongValue error.
