cutthecrap.utils.striterators

Class Sorter

java.lang.Object

cutthecrap.utils.striterators.FilterBase

cutthecrap.utils.striterators.Sorter

All Implemented Interfaces:

IFilter, IPropertySet, Serializable, Cloneable, Comparator

public abstract class Sorter
extends FilterBase
implements Comparator

Used with Sorterator by Striterator to sort iterations.

Cannot be instantiated directly since an implementation of the compare method is required.

It should be noted, that the resulting sorting iterator cannot be produced incrementally since it must access all objects to complete the sort. For this reason care should be taken for sets that may be very large.
