Interface SegmentSetMutualIntersector

  • All Known Implementing Classes:
    MCIndexSegmentSetMutualIntersector, SimpleSegmentSetMutualIntersector 

    public interface SegmentSetMutualIntersector
    An intersector for the red-blue intersection problem. In this class of line arrangement problem, two disjoint sets of linestrings are intersected.

    Implementing classes must provide a way of supplying the base set of segment strings to test against (e.g. in the constructor, for straightforward thread-safety).

    In order to allow optimizing processing, the following condition is assumed to hold for each set:

    • the only intersection between any two linestrings occurs at their endpoints.
    Implementations can take advantage of this fact to optimize processing (i.e by avoiding testing for intersections between linestrings belonging to the same set).

      • process

        void process(Collection segStrings,
             SegmentIntersector segInt)
        Computes the intersections with a given set of SegmentStrings, using the supplied SegmentIntersector.
        Parameters:
        segStrings - a collection of SegmentStrings to node
        segInt - the intersection detector to either record intersection occurences or add intersection nodes to the input segment strings.
