Usage

From source file:org.apache.oozie.workflow.lite.LiteWorkflowValidator.java

private void checkForkTransitions(LiteWorkflowApp app, List<String> transitionsList, NodeDef node)
        throws WorkflowException {
    for (final String t : transitionsList) {
        NodeDef aNode = app.getNode(t);//  w  ww  .  j a  v  a  2 s .  c om
        // Now we have to figure out which node is the problem and what type of node they are (join and kill are ok)
        if (!(aNode instanceof JoinNodeDef) && !(aNode instanceof KillNodeDef)) {
            int count = CollectionUtils.cardinality(t, transitionsList);

            if (count > 1) {
                throw new WorkflowException(ErrorCode.E0744, node.getName(), t);
            }
