Detailed Description

template<class size_type>
class Dune::Functions::FlatMultiIndex< size_type >

A multi-index class with only one level.

This class provides a multi-index interface in the sense that it has operator[] access to individual interfaces. However, since it only supports flat indices of exactly one level, it also has a cast of the multi-index to this index. This is obtianed by deriving from std::array<size_type,1> and adding this cast. Hence multi-indices of type FlatMultiIndex can be used like classic indices.

Constructor & Destructor Documentation

FlatMultiIndex()

template<class size_type >

Dune::Functions::FlatMultiIndex< size_type >::FlatMultiIndex ( std::initializer_list< size_type > const &  l )

inline

Construct from initializer_list.

This is needed because std::array does not have a constructor from initializer list. Instead the list initialization of an std::array is an aggregate initialization and hence not visible in the derived class.

Member Function Documentation

operator const size_type &()

template<class size_type >

Dune::Functions::FlatMultiIndex< size_type >::operator const size_type & ( ) const

inline

Const cast of multi-index to first entry.

Returns

The first (and only) index of this multi-index

operator size_type &()

template<class size_type >

Dune::Functions::FlatMultiIndex< size_type >::operator size_type & ( )

inline

Non-const cast of multi-index to first entry.

Returns

The first (and only) index of this multi-index
