public Class OGLRenderQueue

extends RenderQueue
Class Inheritance
Imports
sun.awt.util.ThreadGroupUtils, sun.java2d.pipe.RenderBuffer, .RenderQueue
OGL-specific implementation of RenderQueue. This class provides a single (daemon) thread that is responsible for periodically flushing the queue, thus ensuring that only one thread communicates with the native OpenGL libraries for the entire process.

Method Summary

Modifier and TypeMethod and Description
public static void
disposeGraphicsConfig(long pConfigInfo)

Disposes the native memory associated with the given native graphics config info pointer on the single queue flushing thread.

public void
flushAndInvokeNow(Runnable r)

Implements abstract sun.java2d.pipe.RenderQueue.flushAndInvokeNow.

Immediately processes each operation currently pending on the buffer, and then invokes the provided task.

public void
flushNow()

Implements abstract sun.java2d.pipe.RenderQueue.flushNow.

Immediately processes each operation currently pending on the buffer.

public static synchronized OGLRenderQueue
getInstance()

Returns the single OGLRenderQueue instance.

public static boolean
isQueueFlusherThread()

Returns true if the current thread is the OGL QueueFlusher thread.

public static void
sync()

Flushes the single OGLRenderQueue instance synchronously.

public static void disposeGraphicsConfig(long pConfigInfo)

Disposes the native memory associated with the given native graphics config info pointer on the single queue flushing thread.

public void flushAndInvokeNow(Runnable r)

Implements abstract sun.java2d.pipe.RenderQueue.flushAndInvokeNow.

Doc from sun.java2d.pipe.RenderQueue.flushAndInvokeNow.

Immediately processes each operation currently pending on the buffer, and then invokes the provided task. This method will block until the entire buffer has been flushed and the provided task has been executed. The queue lock must be acquired before calling this method.

public void flushNow()

Implements abstract sun.java2d.pipe.RenderQueue.flushNow.

Doc from sun.java2d.pipe.RenderQueue.flushNow.

Immediately processes each operation currently pending on the buffer. This method will block until the entire buffer has been flushed. The queue lock must be acquired before calling this method.

getInstanceback to summary
public static synchronized OGLRenderQueue getInstance()

Returns the single OGLRenderQueue instance. If it has not yet been initialized, this method will first construct the single instance before returning it.

isQueueFlusherThreadback to summary
public static boolean isQueueFlusherThread()

Returns true if the current thread is the OGL QueueFlusher thread.

syncback to summary
public static void sync()

Flushes the single OGLRenderQueue instance synchronously. If an OGLRenderQueue has not yet been instantiated, this method is a no-op. This method is useful in the case of Toolkit.sync(), in which we want to flush the OGL pipeline, but only if the OGL pipeline is currently enabled. Since this class has few external dependencies, callers need not be concerned that calling this method will trigger initialization of the OGL pipeline and related classes.
