Constructor Details

MCIndexSegmentSetMutualIntersector

public MCIndexSegmentSetMutualIntersector(Collection baseSegStrings)

Constructs a new intersector for a given set of SegmentStrings.

Parameters:

baseSegStrings - the base segment strings to intersect

MCIndexSegmentSetMutualIntersector

 double overlapTolerance)

Method Details

getIndex

public SpatialIndex getIndex()

Gets the index constructed over the base segment strings. NOTE: To retain thread-safety, treat returned value as immutable!

Returns:

the constructed index

process

public void process(Collection segStrings,
 SegmentIntersector segInt)

Calls SegmentIntersector.processIntersections(SegmentString, int, SegmentString, int) for all candidate intersections between the given collection of SegmentStrings and the set of indexed segments.

Specified by:

process in interface SegmentSetMutualIntersector

Parameters:

segStrings - set of segments to intersect

segInt - segment intersector to use
