GLFrameBufferRenderer

public final void execute(@NonNull Runnable runnable)

Queue a Runnable to be executed on the GL rendering thread. Note it is important this Runnable does not block otherwise it can stall the GL thread.

public final int getBufferFormat()

Returns the HardwareBufferFormat of the buffers that are being rendered into by this GLFrameBufferRenderer

public final @NonNull GLRenderer getGLRenderer()

Returns the GLRenderer used for issuing requests to render into the underlying buffers with OpenGL.

public final int getMaxBuffers()

Returns the number of buffers within the swap chain used for rendering with this GLFrameBufferRenderer

public final @NonNull SyncStrategy getSyncStrategy()

Returns the SyncStrategy used for determining when to create SyncFenceCompat objects in order to handle synchronization. The SyncFenceCompat instance created according to the algorithm specified in the provided SyncStrategy will be passed to the corresponding SurfaceControlCompat.Transaction.setBuffer call in order to ensure the underlying buffer is not presented by the display until the fence signals.

public final long getUsageFlags()

Returns the current usage flag hints of the buffers that are being rendered into by this GLFrameBufferRenderer

public final boolean isValid()

Determines whether or not the GLFrameBufferRenderer is in a valid state. That is the release method has not been called. If this returns false, then subsequent calls to render, and release are ignored

public final void release(boolean cancelPending, Function0<Unit> onReleaseCallback)

Release resources associated with the GLFrameBufferRenderer. After this method is invoked, the GLFrameBufferRenderer is in an invalid state and can no longer handle rendering content.

public final void render()

Render content to a buffer and present the result to the display.

If this GLFrameBufferRenderer has been released, that is isValid returns false, this call is ignored.
