    Member documentation

    • m_nSize – sSet to sizeof( DriverDirectMode_FrameTiming )
    • m_nNumFramePresents – number of times frame was presented
    • m_nNumMisPresented – number of times frame was presented on a vsync other than it was originally predicted to
    • m_nNumDroppedFrames – number of additional times previous frame was scanned out (i.e. compositor missed vsync)

      • DriverDirectModeFrameTiming

        public DriverDirectModeFrameTiming​(java.nio.ByteBuffer container)
        Creates a DriverDirectModeFrameTiming instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

        The created instance holds a strong reference to the container object.
