Class Edge

Namespace

NetTopologySuite.Planargraph

Assembly

NetTopologySuite.dll

Represents an undirected edge of a {PlanarGraph}. An undirected edge in fact simply acts as a central point of reference for two opposite DirectedEdges. Usually a client using a PlanarGraph will subclass Edge to add its own application-specific data and methods.

Constructors

Edge()

Constructs an Edge whose DirectedEdges are not yet set. Be sure to call SetDirectedEdges(DirectedEdge, DirectedEdge).

public Edge()

Edge(DirectedEdge, DirectedEdge)

Constructs an Edge initialized with the given DirectedEdges, and for each DirectedEdge: sets the Edge, sets the symmetric DirectedEdge, and adds this Edge to its from-Node.

public Edge(DirectedEdge de0, DirectedEdge de1)

Parameters

de0 DirectedEdge

de1 DirectedEdge

Fields

dirEdge

The two DirectedEdges associated with this Edge.

protected DirectedEdge[] dirEdge

Field Value

DirectedEdge[]

Properties

IsRemoved

Tests whether this component has been removed from its containing graph.

public override bool IsRemoved { get; }

Property Value

bool

Methods

GetDirEdge(Node)

Returns the DirectedEdge that starts from the given node, or null if the node is not one of the two nodes associated with this Edge.

public DirectedEdge GetDirEdge(Node fromNode)

Parameters

fromNode Node

Returns

DirectedEdge

GetDirEdge(int)

Returns one of the DirectedEdges associated with this Edge.

public DirectedEdge GetDirEdge(int i)

Parameters

i int

0 or 1.

Returns

DirectedEdge

GetOppositeNode(Node)

If node is one of the two nodes associated with this Edge, returns the other node; otherwise returns null.

public Node GetOppositeNode(Node node)

Parameters

node Node

Returns

Node

SetDirectedEdges(DirectedEdge, DirectedEdge)

Initializes this Edge's two DirectedEdges, and for each DirectedEdge: sets the Edge, sets the symmetric DirectedEdge, and adds this Edge to its from-Node.

public void SetDirectedEdges(DirectedEdge de0, DirectedEdge de1)

Parameters

de0 DirectedEdge

de1 DirectedEdge
