class Edge

Parent class(es)

• MeshEntity

An Edge is a MeshEntity of topological dimension 1.

Edge(const Mesh &mesh, std::size_t index)

Create edge on given mesh

@param mesh (Mesh)

The mesh.

@param index (std::size_t)

Index of the edge.

Edge(MeshEntity &entity)

Create edge from mesh entity

@param entity (MeshEntity)

The mesh entity to create an edge from.

double length() const

Compute Euclidean length of edge

@return double

Euclidean length of edge.

@code{.cpp}

UnitSquare mesh(2, 2); Edge edge(mesh, 0); info(“%g”, edge.length());

@endcode

double dot(const Edge &edge) const

Compute dot product between edge and other edge

@param edge (Edge)

Another edge.

@return double

The dot product.

@code{.cpp}

UnitSquare mesh(2, 2); Edge edge1(mesh, 0); Edge edge2(mesh, 1); info(“%g”, edge1.dot(edge2));

@endcode
