Release Notes — Waza API for Java

Latest Update: February 11, 2016.

Waza Application Programming Interface for Java


  • alpha 6
    • Fixed an issue where the Parallel construct could not throw exceptions that were raised in its child processes.
    • Added a new package which extends the waza package with concurrency elements for system input/output. This package includes GPIOInputChannel, GPIOOutputChannel, GPIOTriggeredInputChannel. See the javadoc documentation.
    • Updated the EventObserver. Call-channels and data-channels are clearer recognized.
  • alpha 5
    • Fixed a minor bug. This issue could cause the Choice to freeze.
  • alpha 4
    • Added new channel, guard and option constructors that support single services. These constructors simplify coding.
    • Refactoring channel classes. The call-channel is now the default channel. The channel base classes are UnbufferedChannel and BufferedChannel.
    • Some code improvements for better performance.
  • alpha 3
    • Improved performance of the channel.
    • Alpha 2 reduced the dependency of garbadge collecting. In this update, the unbuffered channel does not require garbage collecting. This independency is required for developing real-time and emdedded applications. Only the buffered channel requires garbage collecting.
    • A few classes are now invisible to the user. This makes the API simpler and smaller.
  • alpha 2
    • Added buffered call-channel and buffered data-channel.
    • Improved performance of channel communication.
    • Solved a race condition causing the Choice to select the wrong option.
    • Change of accept(InterfaceAccept.Sevices[] services, Interface instance) to accept(int[] services, Interface instance).
      The newly added InterfaceAccept.values() is used to specify the services that are to be accepted by the call-channel. For example, chan.accept(new InterfaceAccept.Sevices[] {InterfaceAccept.Services.doThis, InterfaceAccept.Sevices.doThat}, Interface instance) becomes chan.accept(InterfaceAccept.values(InterfaceAccept.Services.doThis, InterfaceAccept.Sevices.doThat), Interface instance). The InterfaceAccept.values() creates an integer array. The int[] services parameter which makes the channel internally a lot faster and the channel does not rely on garbadge collecting.
