SpinningSocketWriter

public SpinningSocketWriter(SocketConnection connection,
                            ILogger logger,
                            IOOutOfMemoryHandler oomeHandler,
                            SocketWriterInitializer initializer)

Method Detail

write

public void write(OutboundFrame frame)

Description copied from interface: SocketWriter

Offers a Frame to be written to the socket. No guarantees are made that the frame is going to be written or received by the other side.

Specified by:

write in interface SocketWriter

Parameters:

frame - the Frame to write.

bytesPending

public long bytesPending()

priorityBytesPending

public long priorityBytesPending()

totalFramesPending

public int totalFramesPending()

Description copied from interface: SocketWriter

Returns the total number of packets (urgent and non normal priority) pending to be written to the socket.

Specified by:

totalFramesPending in interface SocketWriter

Returns:

total number of pending packets.

lastWriteTimeMillis

public long lastWriteTimeMillis()

Description copied from interface: SocketWriter

Returns the last Clock.currentTimeMillis() that a write to the socket completed. Writing to the socket doesn't mean that data has been send or received; it means that data was written to the SocketChannel. It could very well be that this data is stuck somewhere in an io-buffer.

Specified by:

lastWriteTimeMillis in interface SocketWriter

Returns:

the last time something was written to the socket.

initWriteHandler

public void initWriteHandler(WriteHandler writeHandler)

Specified by:

initWriteHandler in interface SocketWriter

getWriteHandler

public WriteHandler getWriteHandler()

Description copied from interface: SocketWriter

Gets the WriteHandler that belongs to this SocketWriter. This method exists for the TextReadHandler, but probably should be deleted.

Specified by:

getWriteHandler in interface SocketWriter

Returns:

the WriteHandler

setProtocol

public void setProtocol(String protocol)

Description copied from interface: SocketWriter

Sets the protocol this SocketWriter should use. This should be called only once at the beginning of the connection. See Protocols

Specified by:

setProtocol in interface SocketWriter

Parameters:

protocol - the protocol

initOutputBuffer

public void initOutputBuffer(ByteBuffer outputBuffer)

Specified by:

initOutputBuffer in interface SocketWriter

close

public void close()

Description copied from interface: SocketWriter

Closes this SocketWriter. This method can be called from an arbitrary thread, and should only be called once. This should be coordinated through the TcpIpConnection.close(String, Throwable) method.

Specified by:

close in interface SocketWriter

write

public void write()
           throws Exception

Throws:

Exception
