Class FastSegmentSetIntersectionFinder

Hierarchy: Object , FastSegmentSetIntersectionFinder

public class FastSegmentSetIntersectionFinder

Finds if two sets of SegmentStrings intersect. Uses indexing for fast performance and to optimize repeated tests against a target set of lines. Short-circuited to return as soon an intersection is found. Immutable and thread-safe.

public FastSegmentSetIntersectionFinder(Collection baseSegStrings)

Creates an intersection finder against a given set of segment strings.

Parameters:: baseSegStrings - baseSegStrings the segment strings to search for intersections

public SegmentSetMutualIntersector getSegmentSetIntersector()

Gets the segment set intersector used by this class. This allows other uses of the same underlying indexed structure.

Returns:: the segment set intersector used

public boolean intersects(Collection segStrings)

Tests for intersections with a given set of target SegmentStrings.

Parameters:: segStrings - segStrings the SegmentStrings to test

Returns:: true if an intersection is found

public boolean intersects(Collection segStrings, SegmentIntersectionDetector intDetector)

Tests for intersections with a given set of target SegmentStrings. using a given SegmentIntersectionDetector.

Parameters:: segStrings - segStrings the SegmentStrings to test; intDetector - intDetector the intersection detector to use

Returns:: true if the detector reports intersections
