Class LinkListener

java.lang.Object
  java.lang.Thread
      com.bbn.openmap.layer.link.LinkListener

All Implemented Interfaces:

LinkPropertiesConstants, java.lang.Runnable

public class LinkListener
extends java.lang.Thread
implements LinkPropertiesConstants

The Link Listener is the object listening from input from the link server, asynchronously. It is launched within its own thread to handle a specific link layer.

Field Detail

linkManager

protected LinkManager linkManager

The Link to use to talk to the client.

layer

protected LinkLayer layer

The LinkLayer to use to do the work.

currentGenerator

protected OMGridGenerator currentGenerator

The generator to use with LinkGrid objects.

listening

protected boolean listening

Used by outsiders to find out if the listener should be started.

Constructor Detail

LinkListener

public LinkListener(LinkManager linkManager,
                    LinkLayer layer,
                    OMGridGenerator generator)

Create child thread that will handle the client.

Parameters:

linkManager - the LinkManager to communicate over.

layer - the LinkLayer to do the work.

generator - the OMGridGenerator.

Method Detail

isListening

public boolean isListening()

A method used by outsiders to figure out if the LinkListener is listening to the server. If false, start() may need to be called to get the listener listening.

setListening

protected void setListening(boolean value)

getListener

protected LinkListener getListener()

startUp

public void startUp()

Use a SwingWorker to launch the listener. Calls start() on the LinkListener from a new thread.

run

public void run()

From the Runnable interface. The thread starts here...

Specified by:

run in interface java.lang.Runnable

Overrides:

run in class java.lang.Thread

listen

public void listen()
            throws java.io.IOException

listen is a method that listens to the server and responds to requests that are made.

Throws:

java.io.IOException
