Is there an Iterator that covers the navigation nodes?

looking for an Iterator that covers the navigation nodes, is there one?

for ( TObjectIterator < UAnyObjClass > It; It; ++It)
    /// ... do stuff

Doesn’t work on object types where its UClass* base is not loaded.

sweet thanks

Edit: Why would they not add the navigation pathnodes into a
Iterator? Epic?

Why would we want to have to scan every fricken object in the world to get the ones your after, to me that is a waste resources to have to scan all objects to get the ones i want. You can’t even add a fricken Iterator to world.h file. < broken.
