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.
