Examples of org.jbpm.graph.exe.Token.lock()

org.jbpm.graph.exe.Token.lock()
locks a process instance for further execution. A locked token cannot continue execution. This is a non-persistent operation. This is used to prevent tokens being propagated during the execution of actions. @see #unlock(String)

      // execute the action
      log.debug("executing " + action);
      String lockOwnerId = "token[" + token.getId() + "]";
      try {
        if (actionMustBeLocked) {
          token.lock(lockOwnerId);
        }


        if (UserCodeInterceptorConfig.userCodeInterceptor != null) {
          UserCodeInterceptorConfig.userCodeInterceptor.executeAction(action, executionContext);
        } else {
