All Implemented Interfaces:

Runnable, ReadyRunnable

public final class DiscoveryLink
extends Object
implements ReadyRunnable

This class is designed to discover link among nodes using the collected and the necessary SNMP information. When the class is initially constructed no information is used.

Constructor Detail

DiscoveryLink

public DiscoveryLink()

Constructs a new DiscoveryLink object . The discovery does not occur until the run method is invoked.

Method Detail

run

public void run()

Performs link discovery for the Nodes and save info in DatalinkInterface table on DataBase

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

Specified by:

run in interface Runnable

getScheduler

public Scheduler getScheduler()

Return the Scheduler

Returns:

setScheduler

public void setScheduler(Scheduler scheduler)

Set the Scheduler

Parameters:

scheduler -

schedule

public void schedule()

This Method is called when DiscoveryLink is initialized

Specified by:

schedule in interface ReadyRunnable

getInitialSleepTime

public long getInitialSleepTime()

Returns:

Returns the initial_sleep_time.

setInitialSleepTime

public void setInitialSleepTime(long initial_sleep_time)

Parameters:

initial_sleep_time - The initial_sleep_timeto set.

isReady

public boolean isReady()

Description copied from interface: ReadyRunnable

setSnmpPollInterval

public void setSnmpPollInterval(long interval)

Parameters:

interval - The discovery_link_interval to set.

getSnmpPollInterval

public long getSnmpPollInterval()

Returns:
