软件介绍
Design Patterns 是如何使用常用设计模式及示例。
示例：
class MoneyPile { let value: Int
var quantity: Int
var nextPile: MoneyPile? init(value: Int, quantity: Int, nextPile: MoneyPile?) { self.value = value self.quantity = quantity self.nextPile = nextPile
} func canWithdraw(var v: Int) -> Bool { func canTakeSomeBill(want: Int) -> Bool { return (want / self.value) > 0
} var q = self.quantity while canTakeSomeBill(v) { if (q == 0) { break
}
v -= self.value
q -= 1
} if v == 0 { return true
} else if let next = self.nextPile { return next.canWithdraw(v)
} return false
}
}class ATM {
private var hundred: MoneyPile
private var fifty: MoneyPile
private var twenty: MoneyPile
private var ten: MoneyPile
private var startPile: MoneyPile { return self.hundred
} init(hundred: MoneyPile,
fifty: MoneyPile,
twenty: MoneyPile,
ten: MoneyPile) { self.hundred = hundred self.fifty = fifty self.twenty = twenty self.ten = ten
} func canWithdraw(value: Int) -> String { return "Can withdraw: \(self.startPile.canWithdraw(value))"
}
}
