class SubsetIterator

A SubsetIterator is similar to a MeshEntityIterator but iterates over a specified subset of the range of entities as specified by a MeshFunction that labels the entities.

SubsetIterator(const MeshFunction<std::size_t> &labels, std::size_t label)

Create iterator for given mesh function. The iterator visits all entities that match the given label.

SubsetIterator(const SubsetIterator &subset_iter)
