Detailed Description

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

A class that provides all possible cases a face (in the current space dimension dim) might be subdivided into subfaces.

Member Enumeration Documentation

Possibilities

template<int dim>

enum internal::SubfacePossibilities::Possibilities

inherited

Possible cases of faces being subdivided into subface.

Enumerator
case_none	Do not refine.
case_isotropic	Refine isotropically.

Constructor & Destructor Documentation

SubfaceCase()

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

operator std::uint8_t()

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).

memory_consumption()

template<int dim>

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

staticconstexpr

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

Member Data Documentation

value

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.
