 /**
+ * @brief Creates a new Alpha discard effect
+ *
  * Alpha discard effect is used to discard fragments when the alpha colour value is below a threshold.
  * This is useful for stenciling.
  *
  * Usage example:
  *
  *   ImageActor actor = ImageActor::New( Image( EXAMPLE_IMAGE_PATH ) );
- *   AlphaDiscardEffect alphaDiscardEffect = AlphaDiscardEffect::New();
+ *   ShaderEffect alphaDiscardEffect = CreateAlphaDiscardEffect();
  *   actor.SetShaderEffect( alphaDiscardEffect );
+ *
+ * @return A handle to a newly allocated ShaderEffect.
