Map multiple events to trigger a command only when all events are received (in order if required)

usingCompoundCommandMap.as

// params: command, isOneShot, requireInOrder
compoundCommandMap.mapToEvents(SomeAwesomeCommand, true, true)
    .addRequiredEvent(SomeEvent.SOMETHING_HAPPENED, SomeEvent);
    .addRequiredEvent(SomeOtherEvent.SOMETHING_ELSE_HAPPENED, SomeOtherEvent, 'somethingElseHappened');
    .addRequiredEvent(SomeOtherEvent.STUFF_HAPPENED, SomeOtherEvent, 'stuffHappened');

// in the command itself

[Inject]
public var someEvent:SomeEvent;

[Inject(name='somethingElseHappened')]
public var somethingElseEvent:SomeOtherEvent;

[Inject(name='stuffHappened')]
public var stuffHappenedEvent:SomeOtherEvent;

// etc - but there's a common use case where you'd only be interested in the fact that all 3 signals have fired and wouldn't need the events at all, or would only need the last one.

 

usingCompoundSignalCommandMap.as

// params: command, isOneShot, requireInOrder
compoundSignalCommandMap.mapToSignals(SomeAwesomeCommand, true, true)
    .addRequiredSignal(UserLoadedSignal);
    .addRequiredSignal(AccountOptionsLoadedSignal);
    .addRequiredSignal(PreferencesLoadedSignal);

// in the command itself - most likely you'd need to use VOs so you don't have multiple
// injected values of the same type

[Inject]
public var userVO:UserVO;

[Inject]
public var accountOptionsVO:AccountOptionsVO;

// etc - but there's a use case where you'd only be interested in the fact that all 3 signals have fired and wouldn't need the payloads at all.

good plan
