Class SwingWorker<T>

java.lang.Object
  com.bbn.openmap.util.SwingWorker<T>

All Implemented Interfaces:

ISwingWorker<T>

public abstract class SwingWorker<T>
extends java.lang.Object
implements ISwingWorker<T>

This is the 3rd version of SwingWorker (also known as SwingWorker 3), an abstract class that you subclass to perform GUI-related work in a dedicated thread. For instructions on using this class, see: http://java.sun.com/docs/books/tutorial/uiswing/misc/threads.html Note that the API changed slightly in the 3rd version: You must now invoke start() on the SwingWorker after creating it.

Constructor Summary

SwingWorker()
Start a thread that will call the construct method and then exit.

Method Summary

abstract T	construct() Compute the value to be returned by the get method.
void	execute() For compatibility with old versions of SwingWorker, calls start().
void	finished() Called on the event dispatching thread (not on the worker thread) after the construct method has returned.
T	get() Return the value created by the construct method.
protected java.lang.Object	getValue() Get the value produced by the worker thread, or null if it hasn't been constructed yet.
void	interrupt() A new method that interrupts the worker thread.
boolean	isInterrupted()
void	start() Start the worker thread.

protected java.lang.Object getValue()

Get the value produced by the worker thread, or null if it hasn't been constructed yet.

construct

public abstract T construct()

Compute the value to be returned by the get method.

Called on the event dispatching thread (not on the worker thread) after the construct method has returned.

Specified by:

finished in interface ISwingWorker<T>

interrupt

public void interrupt()

A new method that interrupts the worker thread. Call this method to force the worker to stop what it's doing.

interrupt in interface ISwingWorker<T>

isInterrupted

public boolean isInterrupted()

Specified by:

isInterrupted in interface ISwingWorker<T>

get

public T get()

Return the value created by the construct method. Returns null if either the constructing thread or the current thread was interrupted before a value was produced.

Specified by:

get in interface ISwingWorker<T>

Returns:

the value created by the construct method

start

public void start()

Start the worker thread.

Specified by:

start in interface ISwingWorker<T>

execute

public void execute()

For compatibility with old versions of SwingWorker, calls start().
