All Implemented Interfaces:

StreamChannel, java.io.Closeable, java.io.DataOutput, java.io.Flushable, java.lang.AutoCloseable, java.nio.channels.Channel, java.nio.channels.WritableByteChannel

public final class ChannelBufferUnsafeFramedOutputStream
extends ChannelBufferUnsafeDataOutputStream

Extension of ChannelBufferUnsafeDataOutputStream to write in frames i.e. write the size of frame at the start. This is like TFramedTransport but the max frame size will be limited to the buffer size so that we never create/allocate large buffers and the frame size is only a hint to the receiving server to stop waiting for more data and start processing it.

gfxd 1.1
