BufImgSurfaceManager

extends SurfaceManager

java.lang.Object
↳	sun.awt.image.SurfaceManager
	↳	sun.awt.image.BufImgSurfaceManager

Class Overview

This SurfaceManager variant manages the default (software) surface of a BufferedImage. All rendering to the image will use the software surface as the destination. This is one of the more minimalist implementations of SurfaceManager.

Summary

Fields
protected BufferedImage	bImg	A reference to the BufferedImage whose contents are being managed.
protected SurfaceData	sdDefault	The default (software) surface containing the contents of the BufferedImage.

Public Constructors
	BufImgSurfaceManager(BufferedImage bImg)

Public Methods
SurfaceData	getPrimarySurfaceData() Returns the main SurfaceData object that "owns" the pixels for this SurfaceManager.
SurfaceData	restoreContents() Called from platform-specific SurfaceData objects to attempt to auto-restore the contents of an accelerated surface that has been lost.

Inherited Methods

From class sun.awt.image.SurfaceManager

void	acceleratedSurfaceLost() Notification that any accelerated surfaces associated with this manager have been "lost", which might mean that they need to be manually restored or recreated.
synchronized void	flush() Releases system resources in use by ancillary SurfaceData objects, such as surfaces cached in accelerated memory.
Object	getCacheData(Object key) Return an arbitrary cached object for an arbitrary cache key.
ImageCapabilities	getCapabilities(GraphicsConfiguration gc) Returns an ImageCapabilities object which can be inquired as to the specific capabilities of this Image.
static SurfaceManager	getManager(Image img) Returns the SurfaceManager object contained within the given Image.
abstract SurfaceData	getPrimarySurfaceData() Returns the main SurfaceData object that "owns" the pixels for this SurfaceManager.
abstract SurfaceData	restoreContents() Restores the primary surface being managed, and then returns the replacement surface.
void	setAccelerationPriority(float priority) Called when image's acceleration priority is changed.
void	setCacheData(Object key, Object value) Store an arbitrary cached object for an arbitrary cache key.
static void	setImageAccessor(SurfaceManager.ImageAccessor ia)
static void	setManager(Image img, SurfaceManager mgr)

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.

Fields

protected BufferedImage bImg

A reference to the BufferedImage whose contents are being managed.

protected SurfaceData sdDefault

The default (software) surface containing the contents of the BufferedImage.

Public Constructors

public BufImgSurfaceManager (BufferedImage bImg)

Public Methods

public SurfaceData getPrimarySurfaceData ()

Returns the main SurfaceData object that "owns" the pixels for this SurfaceManager. This SurfaceData is used as the destination surface in a rendering operation and is the most authoritative storage for the current state of the pixels, though other versions might be cached in other locations for efficiency.

public SurfaceData restoreContents ()

Called from platform-specific SurfaceData objects to attempt to auto-restore the contents of an accelerated surface that has been lost.
