This interface models the part of a SNMP request that involves
a specific MIB. One object implementing this interface will be created
for every MIB involved in a SNMP request, and that object will be passed
to the SnmpMibAgent in charge of handling that MIB.
Objects implementing this interface will be allocated by the SNMP engine.
You will never need to implement this interface. You will only use it.

This API is a Sun Microsystems internal API  and is subject
to change without notice.
