inline

Gets the number of edges.

Returns: The number of edges.

◆ get_edge()

Index get_edge	(	Index	f,
		Index	lv
	)		const

inline

Gets the edge index corresponding to (f, lv) – (f, lv+1).

Parameters

[in]	f	Facet index.
[in]	lv	Local vertex index [0, get_vertex_per_facet()[.

Returns: The edge.
