com.sun.management.snmp.agent.SnmpMibGroup
public abstract class SnmpMibGroup
Represents a node in an SNMP MIB which corresponds to a group. This class allows subnodes to be registered below a group, providing support for nested groups. The subnodes are registered at run time when registering the nested groups in the global MIB OID tree.
This class is used by the class generated by mibgen
.
You should not need to use this class directly.

The actual implementation of this method will be generated by mibgen. Usually, this implementation only delegates the job to some other provided runtime class, which knows how to access the MBean. The current toolkit thus provides two implementations:
Both implementations rely upon specific - and distinct, set of mibgen generated methods.
You can override this method if you need to implement some specific policies for minimizing the accesses made to some remote underlying resources.
