Detailed Description

template<typename ordinal_t>
class Stokhos::TotalOrderIndexSet< ordinal_t >::Iterator

Iterator class for iterating over elements of the index set.

Constructor & Destructor Documentation

template<typename ordinal_t >

Stokhos::TotalOrderIndexSet< ordinal_t >::Iterator::Iterator ( ordinal_type  max_order_, const multiindex_type &  index_  )

inline

Constructor.

max_order_ is the maximum order of the set (inclusive) and index_ is the starting multi-index.

Member Function Documentation

template<typename ordinal_t >

Iterator& Stokhos::TotalOrderIndexSet< ordinal_t >::Iterator::operator++ ( void  )

inline

Prefix increment, i.e., ++iterator.

No particular ordering of the indices is guaranteed. The current implementation produces multi-indices sorted lexographically backwards among the elements, e.g., [0 0], [1 0], [2 0], ... [0 1], [1 1], [2 1], ... but one shouldn't assume that. To obtain a specific ordering, one should implement a "less" functional and put the indices in a sorted container such as std::map<>.
