Methods

Add(EdgeEnd)

Adds a node for the start point of this EdgeEnd (if one does not already exist in this map). Adds the EdgeEnd to the (possibly new) node.

public void Add(EdgeEnd e)

Parameters

e EdgeEnd

An EdgeEnd

AddNode(Coordinate)

This method expects that a node has a coordinate value.

public Node AddNode(Coordinate coord)

Parameters

coord Coordinate

A Coordinate

Returns

Node

The Node for the provided Coordinate coord

AddNode(Node)

Adds a Node to this NodeMap. If a Node with the same Coordinate is already present in this NodeMap, their Labels are merged.

public Node AddNode(Node n)

Parameters

n Node

The Node to add

Returns

Node

Either n or a Node with merged Labels

Find(Coordinate)

Searches for a Node at coord position.

public Node Find(Coordinate coord)

Parameters

coord Coordinate

A Coordinate

Returns

Node

The node if found; null otherwise.

GetBoundaryNodes(int)

public IList<Node> GetBoundaryNodes(int geomIndex)

Parameters

geomIndex int

Returns

IList<Node>

GetEnumerator()

public IEnumerator<Node> GetEnumerator()

Returns

IEnumerator<Node>

Write(StreamWriter)

public void Write(StreamWriter outstream)

Parameters

outstream StreamWriter
