问题描述
与JodaTime一起工作，尝试将List [LocalDate]转换为Tuple2 [JodaTime，JodaTime]，以便我可以像这样进行多重协助:
Working with JodaTime, trying to convert a List[LocalDate] to Tuple2[JodaTime, JodaTime] so I can do multi-assigment like so:
val(expire, now) =
List(row.expireDate, new JodaDate) zip (_.toDateTimeAtStartOfDay.getMillis)
当然不会编译.有没有类似的简洁方法可以完成上述操作?我知道我可以手动完成:
which of course does not compile. Is there a similarly concise way to do the above? I know I can just do it manually:
val(expire, now) =
(row.expireDate.toDateTimeAtStartOfDay.getMillis,
new JodaDate().toDateTimeAtStartOfDay.getMillis)
但这有点难看
推荐答案
val Seq(expire, now) =
Seq(row.expireDate, new JodaDate).map(_.toDateTimeAtStartOfDay.getMillis)
