Search for implicit usages of Iterable.iterator() in for-each loop declarations

I have seen that the otherwise fantastic Find Usages in IntelliJ  does not find usages of a class that implements Iterable, and is used in a for-each style loop.

e.g

class IterateMe implements Iterable {
  public Iterator iterator() {
    retur new Iterator(){...}
  }
}


and used like this:

...
IterateMe iterMe = ...
for (Object o : iterMe) {
   ...
}


This for loop is not listed as a usage in my search result.

Anyone got any ideas on this one, or does it quialify as a bug?

Regards,
Olve

Hello Olve,

For performance reasons, our Find Usages functionality doesn't look for implicit
calls, such as implicit calls to toString() or, in this case, iterator().
You may consider it a bug, but we don't currently have any plans to change
this behavior.

e.g

 Iterable {
> public Iterator iterator() {
> retur new Iterator(){...}
> }
> }]]>

and used like this:

 IterateMe iterMe = ...
> for (Object o : iterMe) {
> ...
> }]]>

This for loop is not listed as a usage in my search result.

Ok, too bad. I just wondered, if you have no plans then it is not a bug :-)

Imho it should be a feature, if it is very slow, make it a(nother) check-box in the search field.

Is it possible to find these things in the structural search? I am not very familiar with that part of IntelliJ.

Best regards,
Olve
