gsWeightMapper< T >::Iterator Struct Reference

Detailed Description

template<class T>
struct gismo::gsWeightMapper< T >::Iterator

The Iterator struct Provides fast read access to the mapper data. The implementation guarantees that no data is copied. Can only be constructed from an optimized gsWeightMapper (see gsWeightMapper::optimize() ) by calling fastTargetToSource or fastSourceToTarget.

Typical usage is Iterator myIter=fastTargetToSource(targetId); for( ; myIter ; ++myIter) { myIter.index(); // source index myIter.weight(); // corresponding weight }

It should be compatible with the std::algoriths. The end marker can be obtained with the end() function.

Note that any modification to the gsWeightMapper after the optimize call invalidates all iterators.
