Typedef Documentation

CondensedMask

template<std::size_t Super, std::size_t Sub>

using Dune::ACFem::CondensedMask = typedef IndexConstant<CondenseMaskHelper<IndexConstant<Super>, IndexConstant<Sub> >::value>

Transform the bit-mask given in Sub be removing all bit-positions of zeros in Super.

Sub is required to also only contain zeros at the removed positions.

This is, e.g., used in the model-code in order to compute argument lists for methods with deliberately ommitted parameters.

SubMaskSequence

template<std::size_t Mask, std::size_t RequiredMask = 0UL>

using Dune::ACFem::SubMaskSequence = typedef typename SubMaskSequenceHelper<IndexSequence<>, MaskSequence<Mask>, MaskSequence<RequiredMask> >::type

Generate a sequence of pair-wise distinct sub-bitmasks starting from a given bit-mask.

The generated sequence of bitmask is "ORed" with the value specified by RequiredMask.
