Concrete methods

def empty[A : ClassTag]: ArraySeq[A]

Attributes

Source:
ArraySeq.scala
override def fill[A : ClassTag](n: Int)(elem: => A): ArraySeq[A]

Produces a immutable array containing the results of some element computation a number of times.

Produces a immutable array containing the results of some element computation a number of times.

Attributes

elem

the element computation

n

the number of elements contained in the immutable array.

Returns:

A immutable array that contains the results of n evaluations of elem.

override def tabulate[A : ClassTag](n: Int)(f: Int => A): ArraySeq[A]

Produces a immutable array containing values of a given function over a range of integer values starting from 0.

Produces a immutable array containing values of a given function over a range of integer values starting from 0.

Attributes

f

n

def unsafeWrapArray[T](x: Array[T]): ArraySeq[T]

Wrap an existing Array into an ArraySeq of the proper primitive specialization type without copying.

Wrap an existing Array into an ArraySeq of the proper primitive specialization type without copying. Any changes to wrapped array will break the expected immutability.

Note that an array containing boxed primitives can be wrapped in an ArraySeq without copying. For example, val a: Array[Any] = Array(1) is an array of Object at runtime, containing Integers. An ArraySeq[Int] can be obtained with a cast: ArraySeq.unsafeWrapArray(a).asInstanceOf[ArraySeq[Int]]. The values are still boxed, the resulting instance is an ArraySeq.ofRef. Writing ArraySeq.unsafeWrapArray(a.asInstanceOf[Array[Int]]) does not work, it throws a ClassCastException at runtime.
