Member Function Documentation

◆ areNeighbors()

bool MR::Graph::areNeighbors ( VertId a,
VertId b ) const
inlinenodiscard

returns true if the vertices a and b are neighbors

◆ checkValidity()

MRMESH_API bool MR::Graph::checkValidity ( ) const

verifies that all internal data structures are valid

◆ construct()

MRMESH_API void MR::Graph::construct ( NeighboursPerVertex neighboursPerVertex,
EndsPerEdge endsPerEdge )

constructs the graph from all valid vertices and edges

◆ edgeSize()

size_t MR::Graph::edgeSize ( ) const
inlinenodiscard

returns the number of edge records, including invalid ones

◆ ends()

const EndVertices & MR::Graph::ends ( EdgeId e) const
inlinenodiscard

returns the ends of given edge

◆ findEdge()

MRMESH_API EdgeId MR::Graph::findEdge ( VertId a,
VertId b ) const
nodiscard

finds and returns edge between vertices a and b; returns invalid edge otherwise

◆ merge()

MRMESH_API void MR::Graph::merge ( VertId remnant,
VertId dead,
std::function< void(EdgeId remnant, EdgeId dead)> onMergeEdges )

unites two vertices into one (deleting the second one), which leads to deletion and merge of some edges, for which callback is called

◆ neighbours()

const Neighbours & MR::Graph::neighbours ( VertId v) const
inlinenodiscard

returns all edges adjacent to given vertex

◆ valid() [1/2]

bool MR::Graph::valid ( EdgeId e) const
inlinenodiscard

returns true if given edge is valid

◆ valid() [2/2]

bool MR::Graph::valid ( VertId v) const
inlinenodiscard

returns true if given vertex is valid

◆ validEdges()

const EdgeBitSet & MR::Graph::validEdges ( ) const
inlinenodiscard

returns all valid edges in the graph

◆ validVerts()

const VertBitSet & MR::Graph::validVerts ( ) const
inlinenodiscard

returns all valid vertices in the graph

◆ vertSize()

size_t MR::Graph::vertSize ( ) const
inlinenodiscard

returns the number of vertex records, including invalid ones
