Class IteratedNoder

Nodes a set of ISegmentStrings completely. The set of ISegmentStrings is fully noded; i.e. noding is repeated until no further intersections are detected.

Iterated noding using a Floating precision model is not guaranteed to converge, due to round off error. This problem is detected and an exception is thrown. Clients can choose to rerun the noding using a lower precision model.

Syntax

public class IteratedNoder : INoder

Constructors

IteratedNoder(PrecisionModel)

Initializes a new instance of the IteratedNoder class.

Declaration

public IteratedNoder(PrecisionModel pm)

Parameters

Type	Name	Description
PrecisionModel	pm

Fields

MaxIterations

Declaration

public const int MaxIterations = 5

Field Value

Type	Description
Int32

Properties

MaximumIterations

Gets/Sets the maximum number of noding iterations performed before the noding is aborted. Experience suggests that this should rarely need to be changed from the default. The default is MaxIterations.

Declaration

public int MaximumIterations { get; set; }

Property Value

Type	Description
Int32

Methods

ComputeNodes(IList<ISegmentString>)

Fully nodes a list of ISegmentStrings, i.e. performs noding iteratively until no intersections are found between segments. Maintains labelling of edges correctly through the noding.

Declaration

public void ComputeNodes(IList<ISegmentString> segStrings)

Parameters

Type	Name	Description
IList<ISegmentString>	segStrings	A collection of SegmentStrings to be noded.

Exceptions

Type	Condition
TopologyException	If the iterated noding fails to converge.

GetNodedSubstrings()

Returns a IList of fully noded ISegmentStrings. The ISegmentStrings have the same context as their parent.

Declaration

public IList<ISegmentString> GetNodedSubstrings()

Returns

Type	Description
IList<ISegmentString>
