Method Summary
def apply (xs : Int*) : Array[Int]
def apply (xs : Char*) : Array[Char]
def apply (xs : Short*) : Array[Short]
def apply (xs : Boolean*) : Array[Boolean]
def apply (xs : Unit*) : Array[Unit]
def apply (xs : Double*) : Array[Double]
def apply (xs : Float*) : Array[Float]
def apply (xs : Byte*) : Array[Byte]
def apply [A <: AnyRef](xs : A*) : Array[A]
Create an array with given elements.
def apply (xs : Long*) : Array[Long]
def concat [T](xs : Seq[T]*) : Array[T]
Concatenate all argument sequences into a single array.
def copy (src : AnyRef, srcPos : Int, dest : AnyRef, destPos : Int, length : Int) : Unit
Copy one array to another. Equivalent to System.arraycopy(src, srcPos, dest, destPos, length), except that this works also for polymorphic and boxed arrays.
def fromFunction [A](f : (Int) => A)(n : Int) : Array[A]
Create an array containing the values of a given function f over given range [0..n)
def fromFunction [A](f : (Int, Int) => A)(n1 : Int, n2 : Int) : Array[Array[A]]
Create an array containing the values of a given function f over given range [0..n1, 0..n2)
def fromFunction [A](f : (Int, Int, Int) => A)(n1 : Int, n2 : Int, n3 : Int) : Array[Array[Array[A]]]
Create an array containing the values of a given function f over given range [0..n1, 0..n2, 0..n3)

Create an array containing the values of a given function f over given range [0..n1, 0..n2, 0..n3, 0..n4, 0..n5)
def fromFunction [A](f : (Int, Int, Int, Int) => A)(n1 : Int, n2 : Int, n3 : Int, n4 : Int) : Array[Array[Array[Array[A]]]]
Create an array containing the values of a given function f over given range [0..n1, 0..n2, 0..n3, 0..n4)
def make [A](n : Int, elem : A) : Array[A]
Create an array containing several copies of an element.
def range (start : Int, end : Int) : Array[Int]
Create a an array containing of successive integers.
def unapplySeq [A](x : Array[A]) : Option[Seq[A]]
This method is called as a result of a pattern match { case Array(...) => } or val Array(...) = ....
