Method Detail

onRead

public void onRead(ByteBuffer src)
            throws Exception

Description copied from interface: ReadHandler

A callback to indicate that data is available in the ByteBuffer to be processed.

Specified by:

onRead in interface ReadHandler

Parameters:

src - the ByteBuffer containing the data to read. The ByteBuffer is already in reading mode and when completed, should not be converted to write-mode using clear/compact. That is a task of the SocketReader.

Throws:

Exception - if something fails while reading data from the ByteBuffer or processing the data (e.g. when a Packet fails to get processed). When an exception is thrown, the TcpIpConnection is closed. There is no point continuing with a potentially corrupted stream.

handlePacket

protected void handlePacket(Packet packet)
