All Implemented Interfaces:

FIXSession, ExtendedFIXSession, com.epam.fixengine.session.SessionStateListenSupport

public abstract class BackupFIXSession
extends InitiatorFIXSession

The BackupFIXSession provides ability to switch the connection from the primary host to backup and vice versa.
The backup session should configured by engine.properties and default.properties configuration files.
