Detailed Description

Unique label for each type of entities that can occur in DUNE grids.

This class has to be extended if a grid implementation with new entity types is added to DUNE.

GeometryType is a C++ "literal type" and can be used in constexpr context if created with a constexpr constructor.

Member Enumeration Documentation

◆ BasicType

enum Dune::GeometryType::BasicType

Each entity can be tagged by one of these basic types plus its space dimension.

Enumerator
simplex	Simplicial element in any nonnegative dimension.
cube	Cube element in any nonnegative dimension.
pyramid	Four sided pyramid in three dimensions.
prism	Prism element in three dimensions.
extended	Other, more general topology, representable as topologyId.
none	Even more general topology, cannot be specified by a topologyId. Two GeometryTypes with 'none' type are equal if and only if they have the same dimension.

Constructor & Destructor Documentation

Constructs the GeometryType object from a static topology representation.

Template Parameters

TopologyType A class providing public static unsigned int members TopologyType::dimension and TopologyType::id. You can e.g. use the Point, Prism and Pyramid structs from the Impl namespace.

Parameters

t	Any object of type TopologyType. The object t itself is ignored.

◆ GeometryType() [6/7]
