Scala:元组的并行赋值

发布于 2024-08-20 01:16:03 字数 418 浏览 9 评论 0原文

是否可以在 Scala 中并行分配元组成员。如果没有,是否有另一种技术可以完成类似的事情?

val players = List(
    new Player("Django Reinhardt", 42), 
    new Player("Sol Hoopii", 57),
    new Player("Marc Ribot", 64)
)

val winners, losers = players.partition(p => p.score > 50)

// winners = List(Player name:Sol Hoopii score: 57, Player name:Marc Ribot score: 64)
// losers = List(Player name:Django Reinhardt score: 42)

Is it possible to assign tuple members in parallel in Scala. if not is there another technique to accomplish something similar?

val players = List(
    new Player("Django Reinhardt", 42), 
    new Player("Sol Hoopii", 57),
    new Player("Marc Ribot", 64)
)

val winners, losers = players.partition(p => p.score > 50)

// winners = List(Player name:Sol Hoopii score: 57, Player name:Marc Ribot score: 64)
// losers = List(Player name:Django Reinhardt score: 42)

val winners, losers = players.partition(p => p.score > 50)

将 (List, List) 元组分配给两个变量。如果你想解压元组,你必须使用

val (winners, losers) = players.partition(p => p.score > 50)

Which 完全符合你的要求。 :-)

val winners, losers = players.partition(p => p.score > 50)

Assignes the (List, List) tuple to two variables. If you want to unpack the tuple you have to use

val (winners, losers) = players.partition(p => p.score > 50)

Which does exactly what you want. :-)
