Class MCIndexNoder

Nodes a set of ISegmentStrings using a index based on MonotoneChains and a ISpatialIndex<T>. The ISpatialIndex<T> used should be something that supports envelope (range) queries efficiently (such as a Quadtree" or HPRtree<T>.

The noder supports using an overlap tolerance distance. This allows determining segment intersection using a buffer for uses involving snapping with a distance tolerance.

Syntax

public class MCIndexNoder : SinglePassNoder, INoder

Constructors

MCIndexNoder()

Initializes a new instance of the MCIndexNoder class.

Declaration

public MCIndexNoder()

MCIndexNoder(ISegmentIntersector)

Initializes a new instance of the MCIndexNoder class.

Declaration

public MCIndexNoder(ISegmentIntersector si)

Parameters

Type	Name	Description
ISegmentIntersector	si	The ISegmentIntersector to use.

MCIndexNoder(ISegmentIntersector, double)

Initializes a new instance of the MCIndexNoder class.

Declaration

public MCIndexNoder(ISegmentIntersector si, double overlapTolerance)

Parameters

Type	Name	Description
ISegmentIntersector	si	The ISegmentIntersector to use.
double	overlapTolerance	The expansion distance for overlap tests

Properties

Index

Declaration

public ISpatialIndex<MonotoneChain> Index { get; }

Property Value

Type	Description
ISpatialIndex<MonotoneChain>

MonotoneChains

Declaration

public IList<MonotoneChain> MonotoneChains { get; }

Property Value

Type	Description
IList<MonotoneChain>

Methods

ComputeNodes(IList<ISegmentString>)

Computes the noding for a collection of ISegmentStrings. Some Noders may add all these nodes to the input ISegmentStrings; others may only add some or none at all.

Declaration

public override void ComputeNodes(IList<ISegmentString> inputSegStrings)

Parameters

Type	Name	Description
IList<ISegmentString>	inputSegStrings

Overrides

SinglePassNoder.ComputeNodes(IList<ISegmentString>)

GetNodedSubstrings()

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

Declaration

public override IList<ISegmentString> GetNodedSubstrings()

Returns

Type	Description
IList<ISegmentString>

Overrides

SinglePassNoder.GetNodedSubstrings()

Implements

INoder
