Scala.collection.TraversableLike
Traversable[A] 유형의 순회 가능한 컬렉션에 대한 템플릿 특성입니다.
Methods
map
def map[B, That](f: A => B)(implicit bf: CanBuildFrom[Repr, B, That]): That = {
def builder = { // extracted to keep method size under 35 bytes, so that it can be JIT-inlined
val b = bf(repr)
b.sizeHint(this)
b
}
val b = builder
for (x <- this) b += f(x)
b.result
}
flatMap
def flatMap[B, That](f: A => GenTraversableOnce[B])(implicit bf: CanBuildFrom[Repr, B, That]): That = {
def builder = bf(repr) // extracted to keep method size under 35 bytes, so that it can be JIT-inlined
val b = builder
for (x <- this) b ++= f(x).seq
b.result
}
