Member Function Documentation

void NetTopologySuite.GeometriesGraph.Node.Add

(

EdgeEnd

e

)

Add the edge to the list of edges at this node.

Parameters

e

override void NetTopologySuite.GeometriesGraph.Node.ComputeIM ( IntersectionMatrix  im )

virtual

Basic nodes do not compute IMs.

Parameters

im

Implements NetTopologySuite.GeometriesGraph.GraphComponent.

Reimplemented in NetTopologySuite.Operation.Relate.RelateNode.

Location NetTopologySuite.GeometriesGraph.Node.ComputeMergedLocation	(	Label	label2,
		int	eltIndex
	)

The location for a given eltIndex for a node will be one of { Null, Interior, Boundary }. A node may be on both the boundary and the interior of a point; in this case, the rule is that the node is considered to be in the boundary. The merged location is the maximum of the two input values.

Parameters

label2
eltIndex

void NetTopologySuite.GeometriesGraph.Node.MergeLabel

(

Node

n

)

Parameters

n

void NetTopologySuite.GeometriesGraph.Node.MergeLabel

(

Label

label2

)

To merge labels for two nodes, the merged location for each LabelElement is computed. The location for the corresponding node LabelElement is set to the result, as long as the location is non-null.

Parameters

label2

void NetTopologySuite.GeometriesGraph.Node.SetLabel	(	int	argIndex,
		Location	onLocation
	)

Parameters

argIndex
onLocation

void NetTopologySuite.GeometriesGraph.Node.SetLabelBoundary

(

int

argIndex

)

Updates the label of a node to BOUNDARY, obeying the mod-2 boundaryDetermination rule.

Parameters

argIndex

override string NetTopologySuite.GeometriesGraph.Node.ToString

(

)

Returns

void NetTopologySuite.GeometriesGraph.Node.Write

(

TextWriter

outstream

)

Parameters

outstream
