Class ComparatorHasIDComparable<IDTYPE extends Comparable<? super IDTYPE>,DATATYPE extends IHasID<IDTYPE>>

java.lang.Object

com.phloc.commons.compare.AbstractComparator<DATATYPE>

com.phloc.commons.compare.AbstractPartComparatorComparable<DATATYPE,IDTYPE>

com.phloc.commons.id.ComparatorHasIDComparable<IDTYPE,DATATYPE>

Type Parameters:

IDTYPE - The type of the ID

DATATYPE - The type of elements to be compared.

All Implemented Interfaces:

Serializable, Comparator<DATATYPE>

Direct Known Subclasses:

ComparatorHasIDInteger, ComparatorHasIDString, ComparatorTreeItemIDComparable

public class ComparatorHasIDComparable<IDTYPE extends Comparable<? super IDTYPE>,DATATYPE extends IHasID<IDTYPE>>
extends AbstractPartComparatorComparable<DATATYPE,IDTYPE>

This is a collation Comparator for objects that implement the IHasID interface with a class that implements Comparable.
