ChildExpandableSource< VAL > Class Template Reference

#include "lib/iter-explorer.hpp"

Description

template<typename VAL>
class lib::iter_explorer::ChildExpandableSource< VAL >

Interface to indicate and expose the ability for child expansion.

This interface is used when packaging a IterExplorer pipeline opaquely into IterSource.

Remarks

the depth() call indicates the depth of the child expansion tree. This information can be used by a "downstream" consumer to react according to a nested scope structure.

Todo:

expandChildren() should not return the value pointer. This is just a workaround to cope with the design mismatch in IterSource; the fact that latter just passes around a pointer into the implementation is ugly, dangerous and plain silly. ////////////////////////////////////////////////////////////TICKET #1125 Incidentally, this is also the sole reason why this interface is templated with VAL
