Query Methods | |
bool | isVertex () const |
Return true if entity is a vertex. | |
bool | isLine () const |
Return true if entity is a line segment. | |
bool | isTriangle () const |
Return true if entity is a triangle. | |
bool | isQuadrilateral () const |
Return true if entity is a quadrilateral. | |
bool | isTetrahedron () const |
Return true if entity is a tetrahedron. | |
bool | isPyramid () const |
Return true if entity is a pyramid. | |
bool | isPrism () const |
Return true if entity is a prism. | |
bool | isHexahedron () const |
Return true if entity is a hexahedron. | |
bool | isSimplex () const |
Return true if entity is a simplex of any dimension. | |
bool | isCube () const |
Return true if entity is a cube of any dimension. | |
bool | isNone () const |

Check for inequality. | |
bool | operator< (const GeometryType &other) const |
less-than operation for use with maps | |
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.
Member Enumeration Documentation
◆ BasicType
Each entity can be tagged by one of these basic types plus its space dimension.
Constructor & Destructor Documentation
◆ GeometryType() [1/2]
|
inline |
Constructor, using the topologyId (integer) and the dimension.
- Note
- the topologyId is a binary encoded representation of the TypologyType, users are encouraged to use the GeometryType(TopologyType t) constructor.
◆ GeometryType() [2/2]
template<class TopologyType >
|
inlineexplicit |
Constructor from static TopologyType class.
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 topologytypes.hh.
- Parameters
-
t Any object of type TopologyType. The object t itself is ignored.
Member Function Documentation
◆ makeFromVertices()
|
inline |
Construct the correct geometry type given the dimension and the number of vertices.
- Note
- This code only works up to dimension 3. In higher dimensions the number of vertices does not uniquely identify the type of polyhedron.
