Class DefaultComparator

java.lang.Object

rs.baselib.util.DefaultComparator

All Implemented Interfaces:

Comparator<Object>

public class DefaultComparator
extends Object
implements Comparator<Object>

Default comparator for objects. The comparator compares NULL-safe and evaluates interfaces that help when comparing, such as Comparable, IDisplayProvider and IDisplayable. If none of these interfaces are implemented then the Object.toString() values will be ignore with String.compareToIgnoreCase(String).
