Class BasicSegmentString

  • All Implemented Interfaces:
    SegmentString 

    public class BasicSegmentString
extends Object
implements SegmentString
    Represents a list of contiguous line segments, and supports noding the segments. The line segments are represented by an array of Coordinates. Intended to optimize the noding of contiguous segments by reducing the number of allocated objects. SegmentStrings can carry a context object, which is useful for preserving topological or parentage information. All noded substrings are initialized with the same context object.

        public BasicSegmentString(Coordinate[] pts,
                          Object data)
        Creates a new segment string from a list of vertices.
        Parameters:
        pts - the vertices of the segment string
        data - the user-defined data of this segment string (may be null)
