public MessageType decodeSingleMessage(ByteBuffer buffer)

Description copied from interface: ProtocolMessageHandler

Converts data from a ByteBuffer into a message for processing by handleMessage. Implementations *must* ensure that buffer.position() reflects the data consumed before returning. Do *not* make synchronous NIO calls from this method (or do anything else long-running).

Specified by:

decodeSingleMessage in interface ProtocolMessageHandler<MessageType>

Parameters:

buffer - The buffer

Returns:

A message for handleMessage to process, or null if the buffer does not contain a complete message

handleMessage

public void handleMessage(Object message)

Description copied from interface: ProtocolMessageHandler

Does application-level processing of a message.

Specified by:

handleMessage in interface ProtocolMessageHandler<MessageType>

Parameters:

message - The message, previously returned by a call to decodeSingleMessage
