Method Detail

run

public void run()

processBuffer

protected void processBuffer(SocketChannel socketChannel,
                             ByteBuffer socketBuffer)
                      throws InterruptedException,
                             IOException

Process the contents that have been read into the buffer. Allow sub-classes to override this behavior.

Parameters:

socketChannel - the channel the data was read from

socketBuffer - the buffer the data was read into

Throws:

InterruptedException - if interrupted when queuing events

IOException

getDelimiter

public byte getDelimiter()

Specified by:

getDelimiter in class SocketChannelHandler<E extends Event<SocketChannel>>

Returns:

the byte used as the delimiter between messages for the given handler
