public final class SnmpPollRequest

extends SnmpRequest

This class inherits from SnmpRequest and adds functionality to refire request to achieve the desired periodic polling. Any kind of error will cause the polling operation to stop. This is supported only for SnmpGet, SnmpGetNext and SnmpWalk operations. These requests can be created by the convenience methods provided in the SnmpManagerSrvIf interface.

For SnmpGet and SnmpGetNext operations, every polling cycle is started with the original SnmpVarbindList specified. The walk operation is done on the response SnmpVarbindList until the first list meets the specified condition with testOid.

These requests can be configured with options for performance reasons. For example, if the user does not want this request to participate in multilex operation, it could be disabled.

The user needs to explicitly cancel the poll operation to terminate polling operation.

Parameters:

group - SnmpSession object for this request.

peer - SnmpPeer object for this request.
