Class Overview

The proxy class contains the logic for when to replace a SurfaceData with a cached OGL Texture and the code to create the accelerated surfaces.

Inherited Methods

From class sun.java2d.SurfaceDataProxy

void	activateDisplayListener() This method should be called from subclasses which create cached SurfaceData objects that depend on the current properties of the display.
void	displayChanged() Invoked when the display mode has changed.
boolean	flush(boolean deaccelerated) Flush all cached resources as per the FlushableCacheData interface.
synchronized void	flush() Actively flushes (drops and invalidates) the cached surface so that it can be reclaimed quickly.
StateTracker	getRetryTracker(SurfaceData srcData) If the subclass is unable to validate or create a cached SurfaceData then this method will be used to get a StateTracker object that will indicate when to attempt to validate the surface again.
void	invalidate() Sets the valid state to false so that the next time this proxy is fetched to generate a replacement SurfaceData, the code in SurfaceData knows to replace the proxy first.
boolean	isAccelerated() Returns true iff this SurfaceData proxy is still valid and if it has a currently cached replacement that is also valid and current.
static boolean	isCachingAllowed()
abstract boolean	isSupportedOperation(SurfaceData srcData, int txtype, CompositeType comp, Color bgColor) Determine if an alternate form for the srcData is needed and appropriate from the given operational parameters.
boolean	isValid() Returns true iff this SurfaceData proxy is still the best way to control caching of the given source on the given destination.
void	paletteChanged() Invoked when the palette has changed.
SurfaceData	replaceData(SurfaceData srcData, int txtype, CompositeType comp, Color bgColor) This method attempts to replace the srcData with a cached version.
void	updateSurfaceData(SurfaceData srcData, SurfaceData dstData, int w, int h) This is the default implementation for updating the cached SurfaceData from the source (primary) SurfaceData.
void	updateSurfaceDataBg(SurfaceData srcData, SurfaceData dstData, int w, int h, Color bgColor) This is an alternate implementation for updating the cached SurfaceData from the source (primary) SurfaceData using a background color for transparent pixels.
abstract SurfaceData	validateSurfaceData(SurfaceData srcData, SurfaceData cachedData, int w, int h) Construct an alternate form of the given SurfaceData.

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 Constructors

public OGLSurfaceDataProxy (OGLGraphicsConfig oglgc, int transparency)

Public Methods

public static SurfaceDataProxy createProxy (SurfaceData srcData, OGLGraphicsConfig dstConfig)

public boolean isSupportedOperation (SurfaceData srcData, int txtype, CompositeType comp, Color bgColor)

Determine if an alternate form for the srcData is needed and appropriate from the given operational parameters.

public SurfaceData validateSurfaceData (SurfaceData srcData, SurfaceData cachedData, int w, int h)

Construct an alternate form of the given SurfaceData. The contents of the returned SurfaceData may be undefined since the calling code will take care of updating the contents with a subsequent call to updateSurfaceData.

If the method returns null then there was a problem with allocating the accelerated surface. The getRetryTracker() method will be called to track when to attempt another revalidation.
