Interface IComparator<DATATYPE>

Type Parameters:

DATATYPE - The data type to be compared

All Superinterfaces:

Comparator<DATATYPE>, Serializable

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@NotThreadSafe
 @FunctionalInterface
public interface IComparator<DATATYPE>
extends Comparator<DATATYPE>, Serializable

A special interface that combines Comparator and Serializable for easier reuse since Comparators should be Serializable.
