public class AbstractFramedStreamSinkConduit extends AbstractStreamSinkConduit<StreamSinkConduit>
When a write takes place all frames are attempted to be written out at once via a gathering write. Frames can be
queued via queueFrame(io.undertow.conduits.AbstractFramedStreamSinkConduit.FrameCallBack, java.nio.ByteBuffer...)
.
