      com.monkeycoder.monkeyfractal.base.FractalThreadManager

All Implemented Interfaces:

java.lang.Runnable

public class FractalThreadManager
extends java.util.Observable
implements java.lang.Runnable

This is a manager class that provides threading control for FractalPlugins. For a plugin to function properly under this manager in the multi-threaded environment it provides, there are a few optional things that should be added into the code.

Originally part of the MonkeyFractal project.

public FractalThreadManager()

Constructs a new FractalThreadManager.

FractalThreadManager

public FractalThreadManager(FractalPlugin inFp)

Constructs a new FractalThreadManager with the specified FractalPlugin to manage.

Parameters:

inFp - The FractalPlugin to manage in a threaded fashion.

Method Detail

setFractalPlugin

public void setFractalPlugin(FractalPlugin inFp)

Sets a new FractalPlugin to manage.

Parameters:

inFp - The FractalPlugin to manage in a threaded fashion.

run

public void run()

This manages the process of generating the fractal. This method is called automatically when start() is called on its containing Thread.

Specified by:

run in interface java.lang.Runnable

See Also:

Thread.start()

sendUpdate

public void sendUpdate(UpdateMessage inMessage)

Relays an UpdateMessage to whatever is observing this class.

Parameters:

inMessage - The update that will be sent to observers.

getFractalBuffer

public FractalBuffer getFractalBuffer()

This function returns the generated FractalBuffer. Calling this method prior to receiving an UpdateMessage.UPDATE_FRACTAL_COMPLETE will result in receiving an unknown FractalBuffer. It may contain prior renders or be null.

Returns:

The FractalBuffer that was returned by generateFractal() on the FractalPlugin.
