Interface RectangleIntersector

public interface RectangleIntersector

An interface for determining which rectangles in a collection intersect a given rectangle.

Method Summary

void	execute(jdsl.core.api.ObjectIterator oi) Initializes the RectangleIntersector with the given set of Rectangle2Ds.
jdsl.core.api.ObjectIterator	getIntersected(jdsl.geomobj.api.Rectangle2D rect) Finds rectangles that intersect the given rectangle.

Method Detail

execute

public void execute(jdsl.core.api.ObjectIterator oi)
             throws java.lang.ClassCastException

Initializes the RectangleIntersector with the given set of Rectangle2Ds.

Parameters:

oi - an iterator over the set of Rectangle2Ds.

Throws:

java.lang.ClassCastException - if an object in the iterator is not a Rectangle2D.

getIntersected

public jdsl.core.api.ObjectIterator getIntersected(jdsl.geomobj.api.Rectangle2D rect)
                                            throws java.lang.IllegalStateException

Finds rectangles that intersect the given rectangle. Rectangles sharing only a point or edge are not considered intersecting.

Parameters:

rect - the query rectangle.

Returns:

an iterator over the set of intersected rectangles.

Throws:

java.lang.IllegalStateException - if execute() was not called first.
