There might be no necessary sort order of a tree.

So you first need to invent a usable sort order and set up the enumerator accordingly. An Enumerator can work on any sort order it only needs to be strict.
Regarding performance it is essential to use a sort order that allows for quickly finding the elements one after the other.
