Interface IGuiCard

All Known Implementing Classes:

GuiCard, GuiCardProxy

public interface IGuiCard

This interface must be implemented by cards that will be used in the compsci108 Solitaire package. There are only two methods required for a card class to be used in the compsci 108 gui Solitaire package: one that provides a card's ID, ane one that indicates whether a card is face up.

The interface method getCardID must be implemented to return a lower-case string such as "as", "ah", "ac", "ad", ... "4h", "5h", and so on where the rank is the first character and it's one of "a23456789tjqk" and the suit is a single character from "shcd".

To facilitate returning appropriate IDs implementers are urged to use this interface's constant String arrays for accessing appropriate strings, e.g., IGuiCard.rankPrefixes[0] returns the appropriate string for an ace -- "a" and IGuiCard.rankPrefixes[12] returns the appropriate string for a king -- "k".

Note that for accessing these constants that "ace" is 0, "two" is 1, and "king" is 12. However, the actual rank of a card representing an ace can be 14 or 1 or any number, e.g., when returned by a card's getRank method if there is such a method. The two methods in this interface are used in the GUI, but not as part of any game (though they could be so used).

Method Detail

getCardId

java.lang.String getCardId()

Return a value used in the compsci108 gui Solitaire package, the returned value must obey a contract: it's a two character lowercase string with first character the rank, the second the suit. The rank characters are from "a23456789tjqk" and the suit characters are from "shcd".

Returns:

a card's id according to the contract specified in this class

isFaceUp

boolean isFaceUp()

Return true when the card is face up, and false otherwise.

Returns:

true if and only if the card is face up

equals

boolean equals(IGuiCard other)
