overlapAreaThenAreaIncreaseThenAreaComparator

public static <T extends HasGeometry> Comparator<HasGeometry> overlapAreaThenAreaIncreaseThenAreaComparator(Rectangle r,
                                                                                                            List<T> list)

areaIncreaseThenAreaComparator

public static <T extends HasGeometry> Comparator<HasGeometry> areaIncreaseThenAreaComparator(Rectangle r)

ascendingDistance

public static <T,S extends Geometry> Comparator<Entry<T,S>> ascendingDistance(Rectangle r)

Returns a comparator that can be used to sort entries returned by search methods. For example:

search(100).toSortedList(ascendingDistance(r))

Type Parameters:

T - the value type

S - the entry type

Parameters:

r - rectangle to measure distance to

Returns:

a comparator to sort by ascending distance from the rectangle
