Interface SegmentString

  • All Known Subinterfaces:
    NodableSegmentString
    All Known Implementing Classes:
    BasicSegmentString, NodedSegmentString
    public interface SegmentString
    An interface for classes which represent a sequence of contiguous line segments. SegmentStrings can carry a context object, which is useful for preserving topological or parentage information.
