Method Details

discover

public abstract void discover()
                       throws InterruptedException

Perform the driver discovery. This method runs in its own separate thread.

To notify the client that a new driver is discovered, the newConnection(DriverConnectionInfo) method must be called.

Throws:

InterruptedException - if the thread running this method is still alive when the component that started it (a JPPF client or driver) is closed or shut down.

newConnection

protected void newConnection(E info)

Notify that a new driver was discovered.

Parameters:

info - encapsulates the driver connection information and configuration,

shutdown

public void shutdown()

Shut this discovery down. This method is intended to be overriden in subclasses to allow user-defined cleanup operations.

Caution: this method is called in a different thread from the one that runs the discover() method.
