sun.java2d.pipe.RenderBuffer
The RenderBuffer class is a simplified, high-performance, Unsafe wrapper used for buffering rendering operations in a single-threaded rendering environment. It's functionality is similar to the ByteBuffer and related NIO classes. However, the methods in this class perform little to no alignment or bounds checks for performance reasons. Therefore, it is the caller's responsibility to ensure that all put() calls are properly aligned and within bounds: - int and float values must be aligned on 4-byte boundaries - long and double values must be aligned on 8-byte boundaries This class only includes the bare minimum of methods to support single-threaded rendering. For example, there is no put(double[]) method because we currently have no need for such a method in the STR classes.

        try {
            // make sure we make the context associated with the given
            // GraphicsConfig current before disposing the native resources
            OGLContext.setScratchSurface(pConfigInfo);


            RenderBuffer buf = rq.getBuffer();
            rq.ensureCapacityAndAlignment(12, 4);
            buf.putInt(DISPOSE_CONFIG);
            buf.putLong(pConfigInfo);


            // this call is expected to complete synchronously, so flush now
            rq.flushNow();
        } finally {
            rq.unlock();
