All Implemented Interfaces:

Sortter

Direct Known Subclasses:

BiDirBubbleSort, BubbleSort, QuickSort

public abstract class AbstractSort

extends java.lang.Object

implements Sortter

The abstract base class for the generic sorting routines. You will need to define a comparison method using the Compare interface and set the comparer before calling sort. If this is not done, then an IllegalArgumentException will be thrown. A default swapper is implemented so that it is not necessary to define an instance of the Swapper interface.
