My device

© Franck.Barbier@FranckBarbier.com

My device is a software case study, which is implemented in State Chart XML (SCXML) and PauWare. PauWare is a Java engine for executing Harel's Statecharts in general.

Application Programming Interface -API-: Javadoc.

This case study aims at illustrating complex behaviors based on orthogonality (i.e., parallel states) and event sending (e.g., event self-sending as follows: ^self.request h).

• My device SCXML document My_device.scxml . For editing purposes, you may use a simple editor SCXML-editor.jar  with associated execution statement: java -jar SCXML-editor.jar
• Java SE application (PauWare ver. 1.3 PauWare_Java_EE.zip ) as a Ant project My_device_JavaFX.zip 
• Java SE application (PauWare2) as a Maven project My_device.PauWare2Web.zip 

• This application has been designed and tested by means of PauWare ver. 2.0 (a.k.a. PauWare2, Sept. 2021). This application also reuses PauWare2Web, a PauWare2 add-on, which allows the dynamic simulation of Harel's Statecharts in a Web browser. While PauWare2 is based on Java 9, PauWare2Web requires Java 11.
• After downloading My_device.PauWare2Web.zip , PauWare2 PauWare2.zip  and PauWare2Web PauWare2Web.zip  must be made accessible as Maven dependencies. PauWare2Web itself requires third-party libraries that are downloaded by Maven:
  • Java API for Processing JSON software is linked to PauWare2Web as a runtime library.
  • PlantUML Java software is linked to PauWare2Web as a runtime library.
    • Graphviz software (required by PlantUML) is a priori installed on Windows.
    • Graphviz software on macOS may be installed using Homebrew (see also here…).
  • Tyrus Java software is linked to PauWare2Web as a runtime library.
• Note that PauWare2Web can be bypassed in the code (no Web visualization then) by commenting/removing in My_device.java what follows:

_My_device_state_machine = new com.pauware.pauware_engine.Core.StateMachine(… /*, new com.pauware.pauware2web.PauWare2Web_client()*/);
