Example 1 with ClassDelegateCaseVariableListener

use of org.camunda.bpm.engine.impl.variable.listener.ClassDelegateCaseVariableListener in project camunda-bpm-platform by camunda.

the class CaseVariableListenerHandlerTest method testClassDelegateHandling.

@Test
public void testClassDelegateHandling() {
    ExtensionElements extensionElements = SpecUtil.createElement(modelInstance, caseTask, null, ExtensionElements.class);
    CamundaVariableListener variableListener = SpecUtil.createElement(modelInstance, extensionElements, null, CamundaVariableListener.class);
    CamundaField field = SpecUtil.createElement(modelInstance, variableListener, null, CamundaField.class);
    field.setCamundaName("fieldName");
    field.setCamundaStringValue("a string value");
    variableListener.setCamundaClass("a.class.Name");
    // when
    CmmnActivity activity = handler.handleElement(planItem, context);
    List<VariableListener<?>> listeners = activity.getVariableListenersLocal(CaseVariableListener.CREATE);
    Assert.assertEquals(1, listeners.size());
    ClassDelegateCaseVariableListener listener = (ClassDelegateCaseVariableListener) listeners.get(0);
    Assert.assertEquals("a.class.Name", listener.getClassName());
    Assert.assertEquals(1, listener.getFieldDeclarations().size());
    Assert.assertEquals("fieldName", listener.getFieldDeclarations().get(0).getName());
    Object fieldValue = listener.getFieldDeclarations().get(0).getValue();
    assertTrue(fieldValue instanceof Expression);
    Expression expressionValue = (Expression) fieldValue;
    assertEquals("a string value", expressionValue.getExpressionText());
    Assert.assertEquals(listener, activity.getVariableListenersLocal(CaseVariableListener.UPDATE).get(0));
    Assert.assertEquals(listener, activity.getVariableListenersLocal(CaseVariableListener.DELETE).get(0));
}

Example 2 with ClassDelegateCaseVariableListener

use of org.camunda.bpm.engine.impl.variable.listener.ClassDelegateCaseVariableListener in project camunda-bpm-platform by camunda.

the class ItemHandler method initializeVariableListener.

protected CaseVariableListener initializeVariableListener(CmmnElement element, CmmnActivity activity, CmmnHandlerContext context, CamundaVariableListener listener) {
    Collection<CamundaField> fields = listener.getCamundaFields();
    List<FieldDeclaration> fieldDeclarations = initializeFieldDeclarations(element, activity, context, fields);
    ExpressionManager expressionManager = context.getExpressionManager();
    String className = listener.getCamundaClass();
    String expression = listener.getCamundaExpression();
    String delegateExpression = listener.getCamundaDelegateExpression();
    CamundaScript scriptElement = listener.getCamundaScript();
    CaseVariableListener variableListener = null;
    if (className != null) {
        variableListener = new ClassDelegateCaseVariableListener(className, fieldDeclarations);
    } else if (expression != null) {
        Expression expressionExp = expressionManager.createExpression(expression);
        variableListener = new ExpressionCaseVariableListener(expressionExp);
    } else if (delegateExpression != null) {

        variableListener = new DelegateExpressionCaseVariableListener(delegateExp, fieldDeclarations);
    } else if (scriptElement != null) {
        ExecutableScript executableScript = initializeScript(element, activity, context, scriptElement);
        if (executableScript != null) {
            variableListener = new ScriptCaseVariableListener(executableScript);
        }
