inits 方法(或屬性)屬於 scala.collection.mutable.AbstractIterable 類(class),其相關用法說明如下。 用法: def inits: Iterator[Iterable[A]] 迭代這個可迭代集合的 inits。第一個值將是這個可迭代集合,最後一個值將是一個空的可迭代集合,中間值是 init 連續應用的結果。 注意:即使應用於視圖或惰性集合,它...
When you write the same thing in a trait, however, the method implementation to invoke for the super call is undefined when you define the trait. REFERENCE stackoverflow: Scala特质 vs 抽象类,抽象类和特质的区别, andScala编程: 用特质,还是不用特质?
