camunda version ：7.14.0
I have a business scenario where I want to do different jump tests when the node is a main process task or a sub-process task.So, my question is, when the process runs to the 02-01-node, how do I tell if it is an embedded sub-process node or a main process node?What I want is a way to judge from the source code.If my above expression is not clear, I can raise your question.

Hello @top-polarbear, a one-liner approach that could maybe help is looking at the parent of the Task object that you are currently on, and checking whether the parent type is a process or a subprocess.
String parentElementTypeName = task.getParentElement().getElementType().getTypeName();
if (parentElementTypeName == "process") { ... }
I’m sure there are other (probably better too) ways of finding this out, but for the context of your question I hope this helps 
Thank you very much for your answer, but I don’t think it meets all the circumstances.I wrote an example. You can also make a suggestion.
