```
public final class ContextAttribs
extends Object
```
This class represents the context attributes passed to CreateContextAttribs of the ARB_create_context extension.
The attributes supported are described in the following extensions:
Use of this class is optional. If an OpenGL context is created without passing an instance of this class (or ARB_create_context is not supported), the old context creation code will be used. Support for debug and forward compatible mobes is not guaranteed by the OpenGL implementation. Developers may encounter debug contexts being the same as non-debug contexts or forward compatible contexts having support for deprecated functionality.
If the CONTEXT_FORWARD_COMPATIBLE_BIT_ARB flag is used, LWJGL will not load the deprecated functionality (as defined in the OpenGL 3.0 specification), even if the driver exposes the corresponding entry points.
This extension is not supported on MacOS X. However, in order to enable the GL 3.2 context on MacOS X 10.7 or newer, an instance of this class must be passed to LWJGL. The only valid configuration is ContextAttribs(3, 2, CONTEXT_CORE_PROFILE_BIT_ARB), anything else will be ignored.
