Method Detail

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.

makeNothingCurrent

public void makeNothingCurrent()

Makes no context current.

swapBuffers

public boolean swapBuffers(javax.microedition.khronos.egl.EGLSurface eglSurface)

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

Returns:

false on failure

setPresentationTime

public void setPresentationTime(javax.microedition.khronos.egl.EGLSurface eglSurface,
                                long nsecs)

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

isCurrent

public boolean isCurrent(javax.microedition.khronos.egl.EGLSurface eglSurface)

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

querySurface

public int querySurface(javax.microedition.khronos.egl.EGLSurface eglSurface,
                        int what)

Performs a simple surface query.

queryString

public java.lang.String queryString(int what)

Queries a string value.

getGlVersion

public int getGlVersion()

Returns the GLES version this context is configured for (currently 2 or 3).

logCurrent

public void logCurrent(java.lang.String msg)

Writes the current display, context, and surface to the log.

getCurrentSurface

public javax.microedition.khronos.egl.EGLSurface getCurrentSurface()

release

public void release()
