Evaluator Question

[José Cornado]

Hello!

I am about to write a custom evaluator and I have a couple of questions:

When does the evaluate(Path) happen? after calling traverse(Node) or after getting the iterator?

Can the traverse descriptions be reused once generated? Are there any performance gains by reusing it other than the obvious reuse?

Thanks a lot!!

While getting the nodes from the iterator, lazily.

I'm not sure that it can be reused, because it contains a lot of concerns that actually hold state.

But it is cheap to create so you can just encapsulate it in a function.

Ok.

Thanks! It will leave the code as it is and will play with reuse later if it makes sense and it doesn't break.
