Usage

From source file:com.github.woonsan.commons.scxml.examples.helloworld.Main.java

public static void main(String[] args) throws Exception {
    // evaluator instance which is used by SCXML engine to evaluate expressions in SCXML
    Evaluator evaluator = new JexlEvaluator();
    // engine to execute the scxml instance
    SCXMLExecutor executor = new SCXMLExecutor(evaluator, null, new SimpleErrorReporter());

    // parse SCXML URL into SCXML model
    SCXML scxml = SCXMLReader.read(SCXML);
    // set state machine (scxml instance) to execute
    executor.setStateMachine(scxml);//from w  ww .  j a  v a  2  s  .  c  om

    // create root context storing variables and being used by evaluator
    Context rootContext = evaluator.newContext(null);
    // set the root context for the engine
    executor.setRootContext(rootContext);

    // initiate the execution of the state machine
    executor.go();
