Class BasicSegmentString

  • All Implemented Interfaces:
    SegmentString

    public class BasicSegmentString
    extends java.lang.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.
