Detailed Description

template<int dim>
class internal::SubfaceCase< dim >

Constructor & Destructor Documentation

template<int dim>
internal::SubfaceCase< dim >::SubfaceCase ( const typename SubfacePossibilities< dim >::Possibilities  subface_possibility)

Constructor. Take and store a value indicating a particular subface possibility in the list of possible situations specified in the base class.

Member Function Documentation

template<int dim>
internal::SubfaceCase< dim >::operator std::uint8_t ( ) const

Return the numeric value stored by this class. While the presence of this operator might seem dangerous, it is useful in cases where one would like to have code like switch (subface_case)... case SubfaceCase::case_x: ... , which can be written as switch (static_cast<std::uint8_t>(subface_case). Another application is to use an object of the current type as an index into an array; however, this use is deprecated as it assumes a certain mapping from the symbolic flags defined in the SubfacePossibilities base class to actual numerical values (the array indices).

template<int dim>
static constexpr std::size_t internal::SubfaceCase< dim >::memory_consumption ( )
static

Return the amount of memory occupied by an object of this type.

Member Data Documentation

template<int dim>
std::uint8_t internal::SubfaceCase< dim >::value
private

Store the refinement case as a bit field with as many bits as are necessary in any given dimension.
