is_unique()

template<typename vectorT >

bool is_unique

(

const vectorT &

vec

)

Check whether a std::vector does not contain duplicate entries.

---

This function returns true if the std::vector vec does not contain duplicates, and false if it contains duplicates.

Template Parameters

vectorT

Class template for vector.

Parameters

vec	General vector to be checked for duplicates.

Return values

is_unique

True if vector does not contain duplicates and false otherwise.

read_domain()

template<unsigned int hyEdge_dim, unsigned int space_dim, template< typename... > typename vectorT = std::vector, typename pointT = Point<space_dim, float>, typename hyEdge_index_t = unsigned int, typename hyNode_index_t = hyEdge_index_t, typename pt_index_t = hyNode_index_t>

DomainInfo<hyEdge_dim, space_dim, vectorT, pointT, hyEdge_index_t, hyNode_index_t, pt_index_t> read_domain

(

std::string

filename

)

General Function to read domain from input file.

---

At the moment, only self-defined .geo files are supported. These files are supposed to comprise hypergraphs consisting of hypercuboids only. Other versions have not yet been implemented.

Template Parameters

hyEdge_dim	The local dimension of a hyperedge.
space_dim	The dimension of the surrounding space.
vectorT	The typename of a large vector holding e.g. all points.
pointT	The typename of a point.
hyEdge_index_t	The index type for hyperedges. Default is unsigned int.
hyNode_index_t	The index type for hypernodes. Default is hyEdge_index_t.
pt_index_t	The index type for points. Default is hyNode_index_t.

Parameters

filename

Name of the .geo file to be read.

Return values

domain_info

Topological and geometrical information of hypergraph.
