[RaghuVamseedhar]

Understanding Queues and Context is tricky. If you stick to some rules, mappings can be simplified to great extent. Below video has mapping logic for a common scenario.



Rules:-
- Put filter logic on Node elements.
- Map Leaf elements one - to - one.

Avoid:-
- Avoid removeContexts, collapseContexts, mapWithDefault on Node elements.
- Avoid context change of Leaf elements.

Do's:-
- Control the occurrence of Node elements by controlling the context of input element.
- Use mapWithDefault for Leaf elements, if required.
