Syntax

public class NodeMap

Constructors

NodeMap(NodeFactory)

Creates an instance of this class using the provided NodeFactory.

Declaration

public NodeMap(NodeFactory nodeFact)

Parameters

Type	Name	Description
NodeFactory	nodeFact	A factory to create Nodes

Properties

Values

Declaration

public IList<Node> Values { get; }

Property Value

Type	Description
IList<Node>

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.

Declaration

public void Add(EdgeEnd e)

Parameters

Type	Name	Description
EdgeEnd	e	An EdgeEnd

AddNode(Coordinate)

This method expects that a node has a coordinate value.

Declaration

public Node AddNode(Coordinate coord)

Parameters

Type	Name	Description
Coordinate	coord	A Coordinate

Returns

Type	Description
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.

Declaration

public Node AddNode(Node n)

Parameters

Type	Name	Description
Node	n	The Node to add

Returns

Type	Description
Node	Either n or a Node with merged Labels

Find(Coordinate)

Searches for a Node at coord position.

Declaration

public Node Find(Coordinate coord)

Parameters

Type	Name	Description
Coordinate	coord	A Coordinate

Returns

Type	Description
Node	The node if found; null otherwise.

GetBoundaryNodes(Int32)

Declaration

public IList<Node> GetBoundaryNodes(int geomIndex)

Parameters

Type	Name	Description
Int32	geomIndex

Returns

Type	Description
IList<Node>

GetEnumerator()

Declaration

public IEnumerator<Node> GetEnumerator()

Returns

Type	Description
IEnumerator<Node>

Write(StreamWriter)

Declaration

public void Write(StreamWriter outstream)

Parameters

Type	Name	Description
StreamWriter	outstream
