Detailed Description

template<typename TDigitalSurfaceContainer> struct DGtal::DigitalSurface< TDigitalSurfaceContainer >::Edge

An edge is a unordered pair of vertices. To make comparisons easier, the smallest vertex is stored before the greatest vertex. Note that loops are legal.

◆ Edge()

template<typename TDigitalSurfaceContainer>
 DGtal::DigitalSurface< TDigitalSurfaceContainer >::Edge::Edge ( const Vertex & v1, const Vertex & v2 )
inline

Constructor from vertices.

Parameters
 v1 the first vertex. v2 the second vertex.

202  if ( v1 <= v2 )
203  {
204  vertices[ 0 ] = v1;
205  vertices[ 1 ] = v2;
206  }
207  else
208  {
209  vertices[ 0 ] = v2;
210  vertices[ 1 ] = v1;
211  }
212  }
Vertex vertices[2]
The two vertices.

◆ operator<()

221  || ( ( vertices[ 0 ] == other.vertices[ 0 ] )
222  && ( vertices[ 1 ] < other.vertices[ 1 ] ) );
223  }
Vertex vertices[2]
