• java.lang.Object

Fields Summary
private HardwareRenderer	mRenderer
private com.android.internal.util.VirtualRefBasePtr	mFinalizer

Constructors Summary
private HardwareLayer(HardwareRenderer renderer, long deferredUpdater) if (renderer == null || deferredUpdater == 0) { throw new IllegalArgumentException("Either hardware renderer: " + renderer + " or deferredUpdater: " + deferredUpdater + " is invalid"); } mRenderer = renderer; mFinalizer = new VirtualRefBasePtr(deferredUpdater);

Methods Summary
static android.view.HardwareLayer	adoptTextureLayer(HardwareRenderer renderer, long layer) return new HardwareLayer(renderer, layer);
public boolean	copyInto(android.graphics.Bitmap bitmap) Copies this layer into the specified bitmap. param bitmap The bitmap to copy they layer into return True if the copy was successful, false otherwise return mRenderer.copyLayerInto(this, bitmap);
public void	destroy() Destroys resources without waiting for a GC. if (!isValid()) { // Already destroyed return; } mRenderer.onLayerDestroyed(this); mRenderer = null; mFinalizer.release(); mFinalizer = null;
public void	detachSurfaceTexture() Indicates that this layer has lost its texture. mRenderer.detachSurfaceTexture(mFinalizer.get());
public long	getDeferredLayerUpdater() return mFinalizer.get();
public long	getLayerHandle() return mFinalizer.get();
public boolean	isValid() Indicates whether this layer can be rendered. return True if the layer can be rendered into, false otherwise return mFinalizer != null && mFinalizer.get() != 0;
private static native int	nGetTexName(long layerUpdater)
private static native boolean	nPrepare(long layerUpdater, int width, int height, boolean isOpaque)
private static native void	nSetLayerPaint(long layerUpdater, long paint)
private static native void	nSetSurfaceTexture(long layerUpdater, android.graphics.SurfaceTexture surface, boolean isAlreadyAttached)
private static native void	nSetTransform(long layerUpdater, long matrix)
private static native void	nUpdateRenderLayer(long layerUpdater, long displayList, int left, int top, int right, int bottom)
private static native void	nUpdateSurfaceTexture(long layerUpdater)
public boolean	prepare(int width, int height, boolean isOpaque) Update the layer's properties. Note that after calling this isValid() may return false if the requested width/height cannot be satisfied param width The new width of this layer param height The new height of this layer param isOpaque Whether this layer is opaque return true if the layer's properties will change, false if they already match the desired values. return nPrepare(mFinalizer.get(), width, height, isOpaque);
public void	setLayerPaint(android.graphics.Paint paint) Update the paint used when drawing this layer. param paint The paint used when the layer is drawn into the destination canvas. see View#setLayerPaint(android.graphics.Paint) nSetLayerPaint(mFinalizer.get(), paint.mNativePaint); mRenderer.pushLayerUpdate(this);
public void	setSurfaceTexture(android.graphics.SurfaceTexture surface) nSetSurfaceTexture(mFinalizer.get(), surface, false); mRenderer.pushLayerUpdate(this);
public void	setTransform(android.graphics.Matrix matrix) Sets an optional transform on this layer. param matrix The transform to apply to the layer. nSetTransform(mFinalizer.get(), matrix.native_instance); mRenderer.pushLayerUpdate(this);
public void	updateSurfaceTexture() nUpdateSurfaceTexture(mFinalizer.get()); mRenderer.pushLayerUpdate(this);
