class ContextualFoldingSet

Declaration

template <class T, class Ctx>
class ContextualFoldingSet { /* full declaration omitted */ };

Description

ContextualFoldingSet - This template class is a further refinement of FoldingSet which provides a context argument when calling Profile on its nodes. Currently, that argument is fixed at initialization time. T must be a subclass of FoldingSetNode and implement a Profile function with signature void Profile(FoldingSetNodeID & , Ctx);
