OGLRenderQueue

extends RenderQueue

java.lang.Object
↳	sun.java2d.pipe.RenderQueue
	↳	sun.java2d.opengl.OGLRenderQueue

Class Overview

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.

Inherited Methods

From class sun.java2d.pipe.RenderQueue

final void	addReference(Object ref) Adds the given Object to the set of hard references, which will prevent that Object from being disposed until the queue has been flushed completely.
final void	ensureAlignment(int first8ByteValueOffset) Inserts a 4-byte NOOP token when necessary to ensure that all 8-byte parameters for the following operation are added to the underlying buffer with an 8-byte memory alignment.
final void	ensureCapacity(int opsize) Ensures that there will be enough room on the underlying buffer for the following operation.
final void	ensureCapacityAndAlignment(int opsize, int first8ByteValueOffset) Convenience method that is equivalent to calling ensureCapacity() followed by ensureAlignment().
abstract void	flushAndInvokeNow(Runnable task) Immediately processes each operation currently pending on the buffer, and then invokes the provided task.
void	flushNow(int position) Updates the current position of the underlying buffer, and then flushes the queue immediately.
abstract void	flushNow() Immediately processes each operation currently pending on the buffer.
final RenderBuffer	getBuffer() Returns the encapsulated RenderBuffer object.
final void	lock() Locks the queue for read/write access.
final boolean	tryLock() Attempts to lock the queue.
final void	unlock() Unlocks the queue.

From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Public Methods

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)

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 ()

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.

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.

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. 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.
