How to get selected nodes from tree

[Sanket Thotange]

I am using 8.5.6 version of angular-tree-component.
I am trying to maintain the tree node selection in localStorage.

UPDATE
I am now able to get selectedNodes from tree using tree.treeModel.selectedLeafNodeIds

But I am unable to get all the selected nodes from tree.

This is resolved.

Also I want to set those selected nodes, next time I visit the same page.

What to do about it?
