Constructor Detail

Dot1dStpGroup

public Dot1dStpGroup(InetAddress address)

The class constructor is used to initialize the collector and send out the initial SNMP packet requesting data. The data is then received and store by the object. When all the data has been collected the passed signaler object is notified using the notifyAll() method.

Parameters:

session - The SNMP session with the remote agent.

signaler - The object signaled when data collection is done.

Method Detail

storeResult

protected void storeResult(SnmpObjId base,
                           SnmpInstId inst,

Overrides:

storeResult in class CollectionTracker

reportGenErr
