Detailed Description

template<class G, class VP, class EP, class VM = IdentityMap, class EM = IdentityMap>
class Dune::Amg::PropertiesGraph< G, VP, EP, VM, EM >

Member Typedef Documentation

◆ EdgeMap

template<class G , class VP , class EP , class VM = IdentityMap, class EM = IdentityMap>
typedef EM Dune::Amg::PropertiesGraph< G, VP, EP, VM, EM >::EdgeMap

The type of the map for converting the EdgeDescriptor to std::size_t.

Has to provide the following method: std::size_t operator[](const EdgeDescriptor& vertex)

The following condition has to be met: Let e1 and e2 be two edge descriptors, e1 < e2, and map be the index map. Then map[v1]<map[v2] has to hold.

◆ VertexMap

template<class G , class VP , class EP , class VM = IdentityMap, class EM = IdentityMap>
typedef VM Dune::Amg::PropertiesGraph< G, VP, EP, VM, EM >::VertexMap

The type of the map for converting the VertexDescriptor to std::size_t.

Has to provide the following method: std::size_t operator[](const VertexDescriptor& vertex)

The following condition has to be met: Let v1 and v2 be two vertex descriptors with v1 < v2 and map be the index map. Then map[v1]<map[v2] has to hold.
