AS3 Signals Changelog:

v0.8 – Maximilian – 2010-11-14

API Changes

• Signals are now MXML-friendly! Example:
  <signals:Signal id="nameChanged">{[String, uint]}</signals:Signal>
  • Constructors are now nullable.
  • valueClasses and eventClass are now writable.
  • Exceptions: NativeMappedSignal and NativeRelaySignal are not yet MXML-friendly.
• Renamed IDeluxeSignal to IPrioritySignal, a more functional name.
• New interfaces to grant access to methods that affect all listeners:
  • ISignalOwner: extends ISignal, IDispatcher, adds removeAll().
  • INativeSignalOwner: extends IPrioritySignal, INativeDispatcher, adds removeAll().
  • These 2 interfaces cannot be merged because dispatch(event:Event) conflicts with dispatch(…valueObjects).
  • Thanks to Brian Heylin for getting the ball rolling.

Fixes

• #24 – Changing NativeSignal.target wasn’t removing listeners from target.
• #32 – FIX: Setting NativeSignal.eventClass to null and dispatching causes null exception.

Build

• Added continuous integration and unit test execution Ant targets: “ci” and “test”.
• Updated AsUnit 4 SWC: test failure call stack is more concise and readable.
• Removed build-asunit.xml as its functionality has been merged into build.xml.

v0.7 – Bubblap – 2010-05-27

API Changes

• Added NativeMappedSignal class from Brian Heylin, with great test coverage.
  • Addresses #16 – Add ability to map native events to signals
• DeluxeSignal has a simpler way to continue bubbling without re-dispatching the event.
  • IBubbleEventHandler.onEventBubbled() now returns true/false to continue/cancel bubbling.
  • Thanks to secoif for the original code and dehash for helping with the merge.
• ISignal and IDeluxeSignal: add(), addOnce() and remove() now return the listener.
  • Thanks to sammyt for the contribution with unit tests.

Fixes

• Improved error message for Signal.dispatch() with too few arguments.

Test Changes

• The test suite is migrated to a newer version of AsUnit 4.
  • Tests now receive an IAsync using [Inject]. No more Asyncleton!
  • The migration pattern can be seen in commit f6878.
  • AllTestsRunner uses a new composition pattern instead of inheritance.
  • Many thanks to Luke Bayes and the Bay Area Computer Club.
• Added more tests for argument dispatching and consolidated in SignalDispatchArgsTest.

v0.6 – GreenDay – 2010-03-17

API Changes

• #15 – IDeluxeSignal and NativeSignal now have valueClasses property

Fixes

• #14 – NativeSignal.addOnce() can’t be reused after native event dispatched

Implementation Changes

• Optimized listeners array cloning to use slice(), which is faster than concat().
• Optimized dispatch() by moving the cloning of listeners to add(), addOnce(), and remove().
• Signal.removeAll() now uses remove() on every listener, instead of fast array clearing. This is intended to avoid possible issues with subclass overrides (as happened before with NativeRelaySignal.remove()).
• Renamed createListenerRelationship() to registerListener().
• Consolidated add() and addOnce() logic in registerListener().
• Removed onceListeners Dictionary from DeluxeSignal and NativeSignal.
• DeluxeSignal and NativeSignal are now more unified in their “once listeners” internal implementations.
• Removed an extra semicolon which made FDT cry (thanks vitch).

Test Changes

• Removed async [Test] metadata because AsUnit 4 no longer uses it.
• Updated the AsUnit 4 SWC to newer version which avoids slowdown of Timers in Flash Player 10.1.
• Added tests for ambiguous relationships in Signal.
• Added tests for adding a listener during a dispatch().

v0.5 – GlassHalfFull – 2010-02-08

• Added versioning to the Ant build, starting at 0.5.
