Class VarBindRequestListenerManager

java.lang.Object
  com.adventnet.snmp.snmp2.agent.VarBindRequestListenerManager

All Implemented Interfaces:

java.io.Serializable

 class VarBindRequestListenerManager
extends java.lang.Object
implements java.io.Serializable

VarBindRequestListenerManager manages all the VarBindRequestListeners which have registered for OIDs

API users do not require access to this class Even for low level API users typically this class wouldn't
