Public Member Functions | |
IndexBuffer (Context *context, bool forceHeadless=false) | |
Construct. Optionally force headless (no GPU-side buffer) operation. | |
virtual | ~IndexBuffer () |
Destruct. | |
virtual void | OnDeviceLost () |
Mark the buffer destroyed on graphics context destruction. May be a no-op depending on the API. | |
virtual void | OnDeviceReset () |
Recreate the buffer and restore data if applicable. May be a no-op depending on the API. | |
virtual void | Release () |
