Class BasicSegmentString

java.lang.Object

org.locationtech.jts.noding.BasicSegmentString

All Implemented Interfaces:

SegmentString

public class BasicSegmentString
extends Object
implements SegmentString

Represents a read-only list of contiguous line segments. This can be used for detection of intersections or nodes. SegmentStrings can carry a context object, which is useful for preserving topological or parentage information.

If adding nodes is required use NodedSegmentString.

Version:

1.7
