Detailed Description

Function Documentation

forEachWhile() [1/2]

template<std::size_t... I, class F >

constexpr bool Dune::ACFem::forEachWhile ( F &&  f, IndexSequence< I... >  = IndexSequence<I...>{}  )

constexpr

Repeat until F returns false.

Obviously, this requires that F returns a boolean value.

Parameters

[in]	s	Integer sequence.
[in]	f	Functor. f has to return a boolean, the loop stops if f returns false. f is called in turn with the values of the integer sequence s. f is passed the loop index as st::integral_constant.

Returns

false if the loop as been terminated before reaching the end of s, otherwise true.

forEachWhile() [2/2]

template<std::size_t... I, class F >

constexpr bool Dune::ACFem::forEachWhile ( IndexSequence< I... >  , F &&  f  )

constexpr

Repeat until F returns false.

Obviously, this requires that F returns a boolean value.

Parameters

[in]	s	Integer sequence.
[in]	f	Functor. f has to return a boolean, the loop stops if f returns false. f is called in turn with the values of the integer sequence s. f is passed the loop index as st::integral_constant.

Returns

false if the loop as been terminated before reaching the end of s, otherwise true.
