org.locationtech.jts.noding.snapround.MCIndexSnapRounder

All Implemented Interfaces:

Noder

@Deprecated
public class MCIndexSnapRounder
extends java.lang.Object
implements Noder

Deprecated.

Not robust. Use SnapRoundingNoder instead.

Uses Snap Rounding to compute a rounded, fully noded arrangement from a set of SegmentStrings. Implements the Snap Rounding technique described in papers by Hobby, Guibas & Marimont, and Goodrich et al. Snap Rounding assumes that all vertices lie on a uniform grid; hence the precision model of the input must be fixed precision, and all the input vertices must be rounded to that precision.

This implementation uses a monotone chains and a spatial index to speed up the intersection tests.

KNOWN BUGS

This implementation is not fully robust.

Method Detail

getNodedSubstrings

public java.util.Collection getNodedSubstrings()

Deprecated.

Description copied from interface: Noder

Returns a Collection of fully noded SegmentStrings. The SegmentStrings have the same context as their parent.

Specified by:

getNodedSubstrings in interface Noder

Returns:

a Collection of SegmentStrings

computeNodes

public void computeNodes(java.util.Collection inputSegmentStrings)

Deprecated.

Description copied from interface: Noder

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

Specified by:

computeNodes in interface Noder

Parameters:

inputSegmentStrings - a collection of SegmentStrings to node

computeVertexSnaps

public void computeVertexSnaps(java.util.Collection edges)

Deprecated.

Snaps segments to all vertices.

Parameters:

edges - the list of segment strings to snap together
