Examples of sun.java2d.SurfaceData.invalidate()

sun.java2d.SurfaceData.invalidate()
Sets this SurfaceData object to the invalid state. All Graphics objects must get a new SurfaceData object via the refresh method and revalidate their pipelines before continuing.

            surfaceDataSw = null;
            surfaceData = getSurfaceDataSw();
            // Now, invalidate the old hardware-based surfaceData
            SurfaceData oldData = surfaceDataHw;
            surfaceDataHw = null;
            oldData.invalidate();
        }
        // If we were created by a Component, get the new GC
        // associated with that object.  Then we won't return
        // IMAGE_INCOMPATIBLE from our next validate() call.
        // 4636548: We need to reset graphicsConfig every time
