Class InteriorIntersectionFinder

    java.lang.Object
      com.vividsolutions.jts.noding.InteriorIntersectionFinder

All Implemented Interfaces:
  SegmentIntersector

public class InteriorIntersectionFinder
extends java.lang.Object
implements SegmentIntersector

Finds an interior intersection in a set of `SegmentString`s, if one exists. Only the first intersection found is reported.

Version:
  1.7

Constructor Summary
`InteriorIntersectionFinder(LineIntersector li)` Creates an intersection finder which finds an interior intersection if one exists

Method Summary
`Coordinate` `getInteriorIntersection()` Gets the computed location of the intersection.
`Coordinate[]` `getIntersectionSegments()` Gets the endpoints of the intersecting segments.
`boolean` `hasIntersection()` Tests whether an intersection was found.
`boolean` `isDone()` Reports whether the client of this class needs to continue testing all intersections in an arrangement.
`void` `processIntersections(SegmentString e0, int segIndex0, SegmentString e1, int segIndex1)` This method is called by clients of the `SegmentIntersector` class to process intersections for two segments of the `SegmentStrings` being intersected.
`void` `setCheckEndSegmentsOnly(boolean isCheckEndSegmentsOnly)` Sets whether only end segments should be tested for interior intersection.

Constructor Detail

### InteriorIntersectionFinder

    public InteriorIntersectionFinder(LineIntersector li)

  Creates an intersection finder which finds an interior intersection if one exists

Parameters:
  `li` - the LineIntersector to use

Method Detail

### setCheckEndSegmentsOnly

    public void setCheckEndSegmentsOnly(boolean isCheckEndSegmentsOnly)

  Sets whether only end segments should be tested for interior intersection. This is a performance optimization that may be used if the segments have been previously noded by an appropriate algorithm. It may be known that any potential noding failures will occur only in end segments.

  Parameters:
    `isCheckEndSegmentsOnly` - whether to test only end segments

### hasIntersection

    public boolean hasIntersection()

  Tests whether an intersection was found.

  Returns:
    true if an intersection was found

### getInteriorIntersection

    public Coordinate getInteriorIntersection()

  Gets the computed location of the intersection. Due to round-off, the location may not be exact.

  Returns:
    the coordinate for the intersection location

### getIntersectionSegments

    public Coordinate[] getIntersectionSegments()

  Gets the endpoints of the intersecting segments.

  Returns:
    an array of the segment endpoints (p00, p01, p10, p11)

### processIntersections

    public void processIntersections(SegmentString e0,
                                     int segIndex0,
                                     SegmentString e1,
                                     int segIndex1)

  This method is called by clients of the `SegmentIntersector` class to process intersections for two segments of the `SegmentStrings` being intersected. Note that some clients (such as `MonotoneChain`s) may optimize away this call for segment pairs which they have determined do not intersect (e.g. by an disjoint envelope test).

  Specified by:
    `processIntersections` in interface `SegmentIntersector`

### isDone

    public boolean isDone()

  Description copied from interface: `SegmentIntersector`
  Reports whether the client of this class needs to continue testing all intersections in an arrangement.

  Specified by:
    `isDone` in interface `SegmentIntersector`
  Returns:
    true if there is no need to continue testing segments
