Hierarchial Data API in qliksense

[Anonymous]

This is regarding Hierarchial Data API. With respect to this new API introduced , what are the benefits since we already have Hierarchy() and Hierarchybelongsto() functions..How to define GetHyperCubeTreeData method. What are the Parameters that are to be passed when defining this method.

What is qpath and how should it be defined? Can any one help me what are the above highlighted qTreenodes and how should they be defined?

And also once we get the response from engine API after executing this request where should this response be used as the response is in JSON format.
