Detailed Description

template<class T, typename index_type = int>
class Utils::NumeratedContainer< T, index_type >

Container for objects that are identified by a numeric id.

This class implements a container that holds T instances and references them by an integral index. New elements get the lowest free index and indexes are reused. The Container keeps a copy of the objects added.
