All Implemented Interfaces:

java.lang.Runnable

---

public abstract class SwingWorkerParam

extends java.lang.Object

implements java.lang.Runnable

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/products/jfc/swingdoc-current/threads2.html * Allow parameters for the construct method. * @see com.xerox.VTM.engine.SwingWorker

private  java.util.Vector	param
private  java.lang.Thread	thread
private  SwingWorkerParam.ThreadVar	threadVar
private  java.lang.Object	value

 

Constructor Summary

SwingWorkerParam(java.util.Vector constructParameters)           Start a thread that will call the construct method * and then exit.

 

Method Summary
abstract  java.lang.Object	construct(java.util.Vector p)           * Compute the value to be returned by the get method.
void	finished()           Called on the event dispatching thread (not on the worker thread) * after the construct method has returned.
java.lang.Object	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.
void	run()           This method will be called by whoever wishes to run your class implementing Runnable.
private  void	setValue(java.lang.Object x)           * Set the value produced by worker thread
