Class ApplicationExtendedFunctionalAdapter

java.lang.Object

quickfix.ApplicationFunctionalAdapter

quickfix.ApplicationExtendedFunctionalAdapter

All Implemented Interfaces:

Application, ApplicationExtended

public class ApplicationExtendedFunctionalAdapter
extends ApplicationFunctionalAdapter
implements ApplicationExtended

This is an adapter implementation of ApplicationExtended interface that transforms the usage into more functional style. It breaks down each interface method into a number of single-method interfaces, which can be supplied with lambda expressions. Each single-method interface has its own add and remove listener method.

1. Support multiple listeners of the same operation, e.g. onLogon. The method of the listeners will be invoked in the same order of when add method was invoked, i.e. FIFO
2. Support fail fast evaluation of canLogOn listeners. False will be returned for the first false value returned from the predicate of canLogOn. Otherwise return true.
3. Provides a thread-safe way to delegate to, add and remove listeners under the assumption that adding and removing listeners are rare.

Method Summary

Modifier and Type	Method and Description
void	addCanLogOnPredicate(Predicate<SessionID> canlogon) Add a Predicate of Session to the canLogon evaluation.
void	addOnBeforeSessionResetListener(Consumer<SessionID> onBeforeSessionReset) Add a Consumer of SessionID to listen to onBeforeSessionReset operation.
boolean	canLogon(SessionID sessionID) If returns false, the session logon is aborted, without sending any logon.
void	onBeforeSessionReset(SessionID sessionID) This method is called before reset a session to allow business application to do some actions(typically sending notification message to client before end of day)
void	removeBeforeSessionResetListener(Consumer<SessionID> onBeforeSessionReset) Remove a Consumer of SessionID from onBeforeSessionReset operation.
void	removeCanLogOnPredicate(Predicate<SessionID> canlogon) Remove a Predicate of Session from the canLogon evaluation.

Method Detail

addCanLogOnPredicate

public void addCanLogOnPredicate(Predicate<SessionID> canlogon)

Add a Predicate of Session to the canLogon evaluation.

Parameters:

canlogon - the Predicate of Session to the canLogon evaluation.

removeCanLogOnPredicate

public void removeCanLogOnPredicate(Predicate<SessionID> canlogon)

Remove a Predicate of Session from the canLogon evaluation.

Parameters:

canlogon - the Predicate of Session to the canLogon evaluation.

addOnBeforeSessionResetListener

public void addOnBeforeSessionResetListener(Consumer<SessionID> onBeforeSessionReset)

Add a Consumer of SessionID to listen to onBeforeSessionReset operation.

Parameters:

onBeforeSessionReset - the Consumer of SessionID to listen to onBeforeSessionReset operation.

removeBeforeSessionResetListener

public void removeBeforeSessionResetListener(Consumer<SessionID> onBeforeSessionReset)

Remove a Consumer of SessionID from onBeforeSessionReset operation.

Parameters:

onBeforeSessionReset - the Consumer of SessionID to listen to onBeforeSessionReset operation.

canLogon

public boolean canLogon(SessionID sessionID)

Description copied from interface: ApplicationExtended

If returns false, the session logon is aborted, without sending any logon.

Specified by:

canLogon in interface ApplicationExtended

Parameters:

sessionID - the session

Returns:

true if the session can be logged on normally

onBeforeSessionReset

public void onBeforeSessionReset(SessionID sessionID)

Description copied from interface: ApplicationExtended
