GenNodeLocationQuery::GenNodeNavigator< PAR > Class Template Reference

Description

template<class PAR>
class stage::interact::GenNodeLocationQuery::GenNodeNavigator< PAR >

Helper to navigate a tree topology represented as GenNode tree.

Basically this is a lib::IterSource<Literal> to encapsulate a sequence of sibling nodes. A "current element" representation is layered on top to allow to expand one level deeper on demand. This "child expansion" is triggered by invoking the expandChildren() function on the iterator front-end provided as LocationQuery::ChildIter
