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

java.lang.Object

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

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

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

Type Parameters:

DATATYPE - The type of elements to be compared.

IDTYPE - The type of the ID of data type

All Implemented Interfaces:

ISerializableComparator<DATATYPE>, Serializable, Comparator<DATATYPE>

Direct Known Subclasses:

ComparatorHasIDInteger, ComparatorHasIDString, ComparatorTreeItemIDComparable

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

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

Description copied from class: AbstractPartComparatorComparable

Implement this method to extract the part to compare from the original object.

Specified by:

getPart in class AbstractPartComparatorComparable<DATATYPE extends IHasID<IDTYPE>,IDTYPE extends Comparable<? super IDTYPE>>

Parameters:

aObject - The object to be compared. Never null.

Returns:

The part of the source object to be compared with the part comparator provided in the constructor. May be null.
