All Implemented Interfaces:

java.lang.AutoCloseable, NativeResource, Pointer
```
public class BGFXCallbackInterface
extends Struct
implements NativeResource
```
Callback interface to implement application specific behavior.
Cached items are currently used for OpenGL and Direct3D 12 binary shaders.

fatal and trace_vargs callbacks can be called from any thread. Other callbacks are called from the render thread.
