numberOfCardsNeededForSet

This method should return an Integer value how many cards are needed for a complete set. Due to the reason MemoSetCard is an abstract class, it is the subclasses' responsibility to implement this method.

isGameCardClass

should return true if the class is a "real" card class

instance creation

createSetWithAllCards

This is not a normal implementation of instance creation, because you do not need only one card and you don't know which cards really exist outside. So here the method returns all possible cards in a set.Due to the reason MemoSetCard is an abstract class, it is the subclasses' responsibility to implement this method.

instance

accessing

clickedByUser

select or deselect the card and test if the user has marked a set. Do some simple verification.

container

a simple acces method to the container slot

container: aGameOrUser

a simple acces method to the container slot

delesectByAllUsers

deselects the card by all users

numberOfCardsNeededForSet

just an interface to ask the class

scoreForSet: aSet

should return the score for a given set. Due to the reason MemoSetCard is an abstract class, it is the subclasses' responsibility to implement this method.

selectedBy

returns a Collection with the users which currently selected this card

default

defaultViewClass

return the view class for this kind of card. Due to the reason MemoSetCard is an abstract class, it is the subclasses' responsibility to implement this method.

testing

isASet: aList

The method gets a list with self class numberOfCardsNeededForSet (see 2.1.1) elements and decide if it is a valid set. Due to the reason MemoSetCard is an abstract class, it is the subclasses' responsibility to implement this method.

isSelected

returns true if self selectedBy is empty (see 2.1.2).

private accessing

deselectByUser: aUser

deselects the card for a given MemoSetUser.

selectByUser: aUser

selects the card for a given MemoSetUser.
