Interface CardComparator

All Superinterfaces:

java.util.Comparator<Card>

All Known Implementing Classes:

DefaultCardComparator, WarCardComparator

public interface CardComparator
extends java.util.Comparator<Card>

Comparison of 2 cards based on their suits and values.

This interface is essentially an extension of Comparator<Card>, Comparator<CardSuit>, Comparator<CardValue>. In fact, the 2 methods declared in this interface are those that would be declared by the last 2 comparators.

Although a Java interface can extend multiples interfaces, it cannot extend the same interface with different parametric types.
