public class GLDebugHelper
extends Object

A helper class for debugging OpenGL ES applications. Wraps the supplied GL interface with a new GL interface that adds support for error checking and logging.

Field Summary

static int	CONFIG_CHECK_GL_ERROR Check glError() after every call.
static int	CONFIG_CHECK_THREAD Check if all calls are on the same thread.
static int	CONFIG_LOG_ARGUMENT_NAMES Print argument names when logging GL Calls.
static int	ERROR_WRONG_THREAD The Error number used in the GLException that is thrown if CONFIG_CHECK_THREAD is enabled and you call OpenGL ES on the a different thread.

Constructor Summary

GLDebugHelper()

wrap

public static javax.microedition.khronos.egl.EGL wrap(javax.microedition.khronos.egl.EGL egl,
                                                      int configFlags,
                                                      Writer log)

Wrap an existing EGL interface in a new EGL interface that adds support for error checking and/or logging.

Parameters:

egl - the existing GL interface. Must implement EGL and EGL10. May optionally implement EGL11 as well.

configFlags - A bitmask of error checking flags.

log - - null to disable logging, non-null to enable logging.

Returns:

the wrapped EGL interface.
