Package nl.colorize.multimedialib.renderer.java2d

Class Java2DRenderer

java.lang.Object

nl.colorize.multimedialib.renderer.java2d.Java2DRenderer

All Implemented Interfaces:

Renderer

Direct Known Subclasses:

HeadlessRenderer

public class Java2DRenderer
extends java.lang.Object
implements Renderer

Implementation of a renderer that uses APIs from the Java standard library. Graphics are displayed using Java 2D, AWT is used to create windows and capture keyboard events, and Java Sound is used to play audio.

The renderer will use two different threads: the rendering thread is used to update the graphics, while the Swing thread is used to listen for user input.

Method Detail

attach

public void attach(RenderCallback callback)

Specified by:

attach in interface Renderer

start

public void start()

Specified by:

start in interface Renderer

initializeWindow

protected javax.swing.JFrame initializeWindow(WindowOptions windowOptions)

getSupportedGraphicsMode

public GraphicsMode getSupportedGraphicsMode()

Specified by:

getSupportedGraphicsMode in interface Renderer

getCanvas

public Canvas getCanvas()

Specified by:

getCanvas in interface Renderer

getStage

public Stage getStage()

Specified by:

getStage in interface Renderer

drawFrame

protected void drawFrame(java.awt.Graphics2D g2)

prepareCanvas

protected void prepareCanvas()

prepareWindowBuffer

protected java.awt.image.BufferStrategy prepareWindowBuffer()

Prepares the window buffer for the current frame. This buffer will be used to display the graphics once the entire frame has been rendered.

blitGraphicsContext

protected void blitGraphicsContext(java.awt.image.BufferStrategy windowBuffer)

Updates the window graphics with the contents of the buffer.

getInputDevice

public InputDevice getInputDevice()

Specified by:

getInputDevice in interface Renderer

getMediaLoader

public MediaLoader getMediaLoader()

Specified by:

getMediaLoader in interface Renderer

getApplicationData

public ApplicationData getApplicationData(java.lang.String appName)

Specified by:

getApplicationData in interface Renderer

getInternetAccess

public InternetAccess getInternetAccess()

Specified by:

getInternetAccess in interface Renderer

takeScreenshot

public java.lang.String takeScreenshot()

Description copied from interface: Renderer

Takes a screenshots of the renderer's current graphics, and saves it to an image. The image is returned as a data URL for a PNG image.

Specified by:

takeScreenshot in interface Renderer

getPlatform

public nl.colorize.util.PlatformFamily getPlatform()

Specified by:

getPlatform in interface Renderer

terminate

public void terminate()

getCallbacks

protected NestedRenderCallback getCallbacks()
