public class GLDebugHelper
extends Object

java.lang.Object
   ↳ android.opengl.GLDebugHelper


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.

Summary

Constants

int CONFIG_CHECK_GL_ERROR

Check glError() after every call.

int CONFIG_CHECK_THREAD

Check if all calls are on the same thread.

int CONFIG_LOG_ARGUMENT_NAMES

Print argument names when logging GL Calls.

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.

Public constructors

Inherited methods

Object clone()

Creates and returns a copy of this object.

boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

void finalize()

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.

final Class<?> getClass()

Returns the runtime class of this Object.

int hashCode()

Returns a hash code value for the object.

final void notify()

Wakes up a single thread that is waiting on this object's monitor.

final void notifyAll()

Wakes up all threads that are waiting on this object's monitor.

String toString()

Returns a string representation of the object.

final void wait(long timeoutMillis, int nanos)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait(long timeoutMillis)

Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

final void wait()

Causes the current thread to wait until it is awakened, typically by being notified or interrupted.
