Class AbstractFixPSequenceExtractor

java.lang.Object

uk.co.real_logic.artio.fixp.AbstractFixPSequenceExtractor

public abstract class AbstractFixPSequenceExtractor
extends java.lang.Object

Class to implement by FIXP implementations in order to correctly index sequence numbers. Some FIXP protocols (eg: iLink3) put sequence numbers inside messages, whilst others (eg: BinaryEntrypoint) use implicit sequence numbers. This provides an abstract where different implementations can implement their choice. It's safe to assume that usage is single threaded.
