java.lang.Object

public class EdgeIntersectionList extends Object
A list of edge intersections along an Edge. Implements splitting an edge with intersections into multiple resultant edges.

  • Constructor Details

    • EdgeIntersectionList

      public EdgeIntersectionList(Edge edge)

  • Method Details

    • add

      public EdgeIntersection add(Coordinate intPt, int segmentIndex, double dist)
      Adds an intersection into the list, if it isn't already there. The input segmentIndex and dist are expected to be normalized.
      Parameters:
      intPt - Point of intersection
      segmentIndex - Index of the containing line segment in the parent edge
      dist - Edge distance of this point along the containing line segment
      Returns:
      the EdgeIntersection found or added

    • iterator

      public Iterator iterator()
      Returns an iterator of EdgeIntersections
      Returns:
      an Iterator of EdgeIntersections

    • isIntersection

      public boolean isIntersection(Coordinate pt)
      Tests if the given point is an edge intersection
      Parameters:
      pt - the point to test
      Returns:
      true if the point is an intersection

    • addEndpoints

      public void addEndpoints()
      Adds entries for the first and last points of the edge to the list

    • addSplitEdges

      public void addSplitEdges(List edgeList)
      Creates new edges for all the edges that the intersections in this list split the parent edge into. Adds the edges to the input list (this is so a single list can be used to accumulate all split edges for a Geometry).
      Parameters:
      edgeList - a list of EdgeIntersections

    • print

      public void print(PrintStream out)
