Method Details

create

public static EglThread create(@Nullable
 EglThread.ReleaseMonitor releaseMonitor,
 @Nullable
 EglBase.Context sharedContext,
 int[] configAttributes,
 @Nullable
 RenderSynchronizer renderSynchronizer)

create

public static EglThread create(@Nullable
 EglThread.ReleaseMonitor releaseMonitor,
 @Nullable
 EglBase.Context sharedContext,
 int[] configAttributes)

release

public void release()

createEglBaseWithSharedConnection

public EglBase createEglBaseWithSharedConnection()

Creates an EglBase instance with the EglThread's EglConnection. This method can be called on any thread, but the returned EglBase instance should only be used on this EglThread's Handler.

getHandler

public android.os.Handler getHandler()

Returns the Handler to interact with Gl/EGL on. Callers need to make sure that their own EglBase is current on the handler before running any graphics operations since the EglThread can be shared by multiple clients.

addExceptionCallback

public void addExceptionCallback(Runnable callback)

Adds a callback that will be called on the EGL thread if there is an exception on the thread.

removeExceptionCallback

public void removeExceptionCallback(Runnable callback)

Removes a previously added exception callback.

scheduleRenderUpdate

public void scheduleRenderUpdate(EglThread.RenderUpdate update)

Schedules a render update (like swapBuffers) to be run in sync with other updates on the next open render window. If the render window is currently open the update will run immediately. This method must be called on the EglThread during a render pass.

onRenderWindowOpen

public void onRenderWindowOpen()

Specified by:

onRenderWindowOpen in interface RenderSynchronizer.Listener

onRenderWindowClose

public void onRenderWindowClose()

Specified by:

onRenderWindowClose in interface RenderSynchronizer.Listener
