Field Detail

public static final Card UNKNOWN_CARD

Constructor Detail

Card

public Card(Face face,
            Suit suit)

Method Detail

getSuit

public Suit getSuit()

getFace

public Face getFace()

isFaceUp

public boolean isFaceUp()

Determines whether it's known what suit and face this card is. The server only notifies us the suit and face if we can see it, hence it will be "face up".

Returns:

true iff face != UNKNOWN_FACE and suit != UNKNOWN_SUIT.

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Taken from the example on p.39 of Effective Java by Joshua Bloch. A better solution would be not to implement equals() and hashCode() and to instead make the constructors private and provide a static getCard() method that returns the appropriate card from a static set of cards since cards are a finite set. However, we also have to think about what happens when there are two decks in the game and what that means for equality.

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
