Detailed Description

template<typename T>
struct DGtal::concepts::CUndirectedSimpleLocalGraph< T >

Aim: Represents the concept of local graph: each vertex has neighboring vertices, but we do not necessarily know all the vertices.

Description of concept 'CUndirectedSimpleLocalGraph'

Refinement of

Associated types

Size: an integral type to count the number of vertices.
Vertex: the type for the vertices of the graph (a model of boost::DefaultConstructible, boost::Assignable, boost::CopyConstructible).
VertexSet: the type for storing a set of vertices.
VertexMap: a rebinding structure to associate Value to vertices of model CVertexMap.

Notation

X : A type that is a model of CUndirectedSimpleLocalGraph
x : object of type X
v : object of type Vertex
out : an output iterator of type OutputIterator (model of boost::OutputIterator).
p : a predicate on vertex of type VertexPredicate (model of CVertexPredicate).

Definitions

Valid expressions and semantics

Name	Expression	Return type	Semantics
Degree	x.degree(v)	Size	Returns the degree of vertex `v`
Capacity	x.bestCapacity()	Size	Returns the approximate number of neighbors to be expected. Useful to prepare data structures.
Neighbourhood	x.writeNeighbors<OutputIterator>( out, v )		Writes with the output iterator `out` the neighboring vertices of `v`.
Neighborhood	x.writeNeighbors<OutputIterator,VertexPredicate>( out, v, p )		Writes with the output iterator `out` the neighboring vertices of `v` that satisfy the predicate `p`.
