Method Summary

Modifier and Type	Method	Description
protected void	deallocate()	Override this method to invoke de-allocation of the underlying resource.
void	flush()
ImageInfo	getImageInfo()	Returns an ImageInfo describing the Surface.
static @SharedPtr GraniteSurface	make(RecordingContext rc, ImageInfo info, boolean budgeted, boolean mipmapped, boolean approxFit, int surfaceOrigin, String label)
@SharedPtr GraniteImage	makeImageCopy(Rect2ic subset, boolean mipmapped)
static @SharedPtr GraniteSurface	makeRenderTarget(RecordingContext rc, ImageInfo info, boolean mipmapped, int surfaceOrigin, String label)	While clients hold a ref on a Surface, the backing gpu object does not count against the budget.
protected boolean	onCopyOnWrite(int changeMode)	If the surface is about to change, we call this so that our subclass can optionally fork their backend (copy-on-write) in case it was being shared with the cachedImage.
protected RecordingContext	onGetRecordingContext()
protected Canvas	onNewCanvas()	Allocate a canvas that will draw into this surface.
protected Image	onNewImageSnapshot(Rect2ic subset)	Allocate an Image that represents the current contents of the surface.

Method Details

make

@Nullable
@SharedPtr
public static @SharedPtr GraniteSurface make(RecordingContext rc,
 ImageInfo info,
 boolean budgeted,
 boolean mipmapped,
 boolean approxFit,
 int surfaceOrigin,
 String label)

makeRenderTarget

@Nullable
@SharedPtr
public static @SharedPtr GraniteSurface makeRenderTarget(RecordingContext rc,
 @Nonnull
 ImageInfo info,
 boolean mipmapped,
 int surfaceOrigin,
 @Nullable
 String label)

While clients hold a ref on a Surface, the backing gpu object does not count against the budget. Once a Surface is freed, the backing gpu object may or may not become a scratch (i.e., reusable) resource but, if it does, it will be counted against the budget.

deallocate

protected void deallocate()

Description copied from class: RefCnt

Override this method to invoke de-allocation of the underlying resource.

Overrides:

deallocate in class Surface

flush

public void flush()

getImageInfo

@Nonnull
public ImageInfo getImageInfo()

Description copied from class: Surface

Returns an ImageInfo describing the Surface.

Specified by:

getImageInfo in class Surface

onNewCanvas

protected Canvas onNewCanvas()

Description copied from class: Surface

Allocate a canvas that will draw into this surface. We will cache this canvas, to return the same object to the caller multiple times. We take ownership, and will call unref() on the canvas when we go out of scope.

Specified by:

onNewCanvas in class Surface

onNewImageSnapshot

@Nullable
protected Image onNewImageSnapshot(@Nullable
 Rect2ic subset)

Description copied from class: Surface

Allocate an Image that represents the current contents of the surface. This needs to be able to outlive the surface itself (if need be), and must faithfully represent the current contents, even if the surface is changed after this called (e.g. it is drawn to via its canvas).

If a subset is specified, the impl must make a copy, rather than try to wait on copy-on-write.

Specified by:

onNewImageSnapshot in class Surface

onCopyOnWrite

protected boolean onCopyOnWrite(int changeMode)

Description copied from class: Surface

If the surface is about to change, we call this so that our subclass can optionally fork their backend (copy-on-write) in case it was being shared with the cachedImage.

Returns false if the backing cannot be un-shared.

Specified by:

onCopyOnWrite in class Surface

makeImageCopy

@Nullable
@SharedPtr
public @SharedPtr GraniteImage makeImageCopy(@Nullable
 Rect2ic subset,
 boolean mipmapped)

onGetRecordingContext

protected RecordingContext onGetRecordingContext()

Overrides:

onGetRecordingContext in class Surface
