public javax.microedition.khronos.egl.EGLConfig chooseConfig(javax.microedition.khronos.egl.EGL10 egl,
                                                             javax.microedition.khronos.egl.EGLDisplay display,
                                                             javax.microedition.khronos.egl.EGLContext sharedContext)

chooseConfig

public javax.microedition.khronos.egl.EGLConfig chooseConfig(javax.microedition.khronos.egl.EGL10 egl,
                                                             javax.microedition.khronos.egl.EGLDisplay display)

doChooseConfig

public javax.microedition.khronos.egl.EGLConfig doChooseConfig(javax.microedition.khronos.egl.EGL10 egl,
                                                               javax.microedition.khronos.egl.EGLDisplay display,
                                                               javax.microedition.khronos.egl.EGLConfig[] configs)

getGL

public javax.microedition.khronos.opengles.GL getGL()

releaseSurface

public void releaseSurface(javax.microedition.khronos.egl.EGLSurface eglSurface)

Destroys the specified surface. Note the EGLSurface won't actually be destroyed if it's still current in a context.

createWindowSurface

public javax.microedition.khronos.egl.EGLSurface createWindowSurface(java.lang.Object surface)

Creates an EGL surface associated with a Surface.

If this is destined for MediaCodec, the EGLConfig should have the "recordable" attribute.

createOffscreenSurface

public javax.microedition.khronos.egl.EGLSurface createOffscreenSurface(int width,
                                                                        int height)

Creates an EGL surface associated with an offscreen buffer.

_makeCurrent

public void _makeCurrent(javax.microedition.khronos.egl.EGLSurface eglSurface)

Makes our EGL context current, using the supplied surface for both "draw" and "read".

_makeCurrent

public void _makeCurrent(javax.microedition.khronos.egl.EGLSurface drawSurface,
                         javax.microedition.khronos.egl.EGLSurface readSurface)

Makes our EGL context current, using the supplied "draw" and "read" surfaces.

_swapBuffers

protected boolean _swapBuffers(javax.microedition.khronos.egl.EGLSurface eglSurface)

Calls eglSwapBuffers. Use this to "publish" the current frame.

Returns:

false on failure

_setPresentationTime

protected void _setPresentationTime(javax.microedition.khronos.egl.EGLSurface eglSurface,
                                    long nsecs)

Sends the presentation time stamp to EGL. Time is expressed in nanoseconds.

_isCurrent

protected boolean _isCurrent(javax.microedition.khronos.egl.EGLSurface eglSurface)

Returns true if our context and the specified surface are current.

_querySurface

protected int _querySurface(javax.microedition.khronos.egl.EGLSurface eglSurface,
                            int what)

Performs a simple surface query.
