Detailed Description

An edge consists of pointers to two vertices, an index into the edge list, and a flag that indicates whether the edge is marked or not. There are also some neuron-related values for when the graph is used to define a neural network.

Constructor & Destructor Documentation

CEdge()

CEdge::CEdge	(	CVertex *	p0,
		CVertex *	p1,
		UINT	index
	)

The edge constructor creates an edge between two vertices.

Parameters

p0	Pointer to vertex incident with edge.
p1	Pointer to vertex incident with edge.
index	Index of edge.

Definition at line 38 of file Graph.cpp.

Member Function Documentation

GetIndex()

UINT CEdge::GetIndex

(

)

Reader function for the index.

Returns

The index of this edge in the edge list.

Definition at line 56 of file Graph.cpp.

GetNextVertex()

CVertex * CEdge::GetNextVertex

(

CVertex *

p

)

Get vertex at other end of edge from a vertex. Returns nullptr if this edge is not incident on the given vertex.

Parameters

p	Pointer to a vertex.

Returns

Pointer to the vertex at the other end of the edge.

Definition at line 47 of file Graph.cpp.

GetVertexIndices()

void CEdge::GetVertexIndices	(	UINT &	i0,
		UINT &	i1
	)

Get a pair of vertex indices.

Parameters

i0	[out] Index of a vertex incident with this edge.
i1	[out] Index of the other vertex incident with this edge.

Definition at line 78 of file Graph.cpp.

Mark()

void CEdge::Mark

(

bool

b = true

)

Set or unset the mark flag.

Parameters

b	true to set mark flag (default), false to unset it

Definition at line 63 of file Graph.cpp.

Marked()

bool CEdge::Marked

(

)

Reader function for the mark flag.

Returns

true if marked, false if unmarked.

Definition at line 70 of file Graph.cpp.
