Class NodeDiscovery

java.lang.Object

org.opennms.netmgt.enlinkd.NodeDiscovery

All Implemented Interfaces:

Runnable, ReadyRunnable

Direct Known Subclasses:

NodeDiscoveryBridge, NodeDiscoveryCdp, NodeDiscoveryIpNetToMedia, NodeDiscoveryIsis, NodeDiscoveryLldp, NodeDiscoveryOspf

public abstract class NodeDiscovery
extends Object
implements ReadyRunnable

This class is designed to collect the necessary SNMP information from the target address and store the collected information. When the class is initially constructed no information is collected. The SNMP Session creating and collection occurs in the main run method of the instance. This allows the collection to occur in a thread if necessary.

m_linkd

protected final EnhancedLinkd m_linkd

Constructor Detail

NodeDiscovery

public NodeDiscovery(EnhancedLinkd linkd,
             LinkableSnmpNode node)

Constructs a new SNMP collector for a node using the passed interface as the collection point. The collection does not occur until the run method is invoked.

Parameters:

nodeid -

config - The SnmpPeer object to collect from.

Method Detail

run

public void run()

Performs the collection for the targeted IP address. The success or failure of the collection should be tested via the failed method.

No synchronization is performed, so if this is used in a separate thread context synchronization must be added.

Specified by:

run in interface Runnable

runCollection

protected abstract void runCollection()

getScheduler

public Scheduler getScheduler()

getScheduler

Returns:

a Scheduler object.

setScheduler

public void setScheduler(Scheduler scheduler)

setScheduler

Parameters:

scheduler - a Scheduler object.

schedule
