Class DynamicAcceptorSessionProvider

java.lang.Object

quickfix.mina.acceptor.DynamicAcceptorSessionProvider

All Implemented Interfaces:

AcceptorSessionProvider

public class DynamicAcceptorSessionProvider
extends Object
implements AcceptorSessionProvider

Dynamically defines sessions for an acceptor. This can be useful for applications like simulators that want to accept any connection and dynamically create an associated session. For more complex situations, you can use this class as a starting point for implementing your own AcceptorSessionProvider.

Constructor Detail

DynamicAcceptorSessionProvider

public DynamicAcceptorSessionProvider(SessionSettings settings,
                                      SessionID templateID,
                                      Application application,
                                      MessageStoreFactory messageStoreFactory,
                                      LogFactory logFactory,
                                      MessageFactory messageFactory)

Parameters:

settings - session settings

templateID - this is a session ID for a session definition in the session settings that will be used for default dynamic session values. The BeginString, SenderCompID, and TargetCompID settings will be replaced with those in the received logon message.

application - application for the dynamic sessions

messageStoreFactory - message store factory for the dynamic sessions

logFactory - log factory for the dynamic sessions

messageFactory - message factory for the dynamic sessions

DynamicAcceptorSessionProvider

public DynamicAcceptorSessionProvider(SessionSettings settings,
                                      List<DynamicAcceptorSessionProvider.TemplateMapping> templateMappings,
                                      Application application,
                                      MessageStoreFactory messageStoreFactory,
                                      LogFactory logFactory,
                                      MessageFactory messageFactory)

Parameters:

settings - session settings

templateMappings - this is a list of session ID patterns mapped to session IDs in the settings file. The session IDs represent the template for a specified session ID pattern. The template is used to dynamically create acceptor sessions. Use "*" to represent a wildcard for a pattern element. For example, new SessionID("FIX.4.2", "*", "*") would match for any FIX 4.2 session ID. This allows separate template session configurations for FIX versions (or CompIDs) being accepted dynamically on a single TCP port.

application - application for the dynamic sessions

messageStoreFactory - message store factory for the dynamic sessions

logFactory - log factory for the dynamic sessions

messageFactory - message factory for the dynamic sessions
