Description copied from interface: Persister

This is to be used to store the protocol-id on Messages. Messages are stored on their bare format. The protocol manager will be responsible to code or decode messages. The caveat here is that the first short-sized bytes need to be this constant.

Specified by:

getID in interface Persister<Message>

getEncodeSize

public int getEncodeSize(Message record)

Specified by:

getEncodeSize in interface Persister<Message>

encode
