Method Summary
override def ++ [B >: A](that : Iterable[B]) : Array[B]
Returns an array consisting of all elements of this array followed by all elements of the argument iterable.
def apply (i : Int) : A
The element at given index.

Indices start a 0; xs.apply(0) is the first element of array xs.

Note the indexing syntax xs(i) is a shorthand for xs.apply(i).

def deepEquals (that : Any) : Boolean

Returns true if the two specified arrays are deeply equal to one another.

Two array references are considered deeply equal if both are null, or if they refer to arrays that contain the same number of elements and all corresponding pairs of elements in the two arrays are deeply equal.

See also method deepEquals in the Java class java.utils.Arrays

def deepMkString (sep : String) : String
Returns a string representation of this array object. The string representations of elements (w.r.t. the method deepToString()) are separated by the string sep.
def deepMkString (start : String, sep : String, end : String) : String

Returns a string representation of this array object. The resulting string begins with the string start and is finished by the string end. Inside, the string representations of elements (w.r.t. the method deepToString()) are separated by the string sep. For example:

Array(Array(1, 2), Array(3)).deepMkString("[", "; ", "]") = "[[1; 2]; [3]]"

def deepToString : String
override def drop (n : Int) : Array[A]
Returns this array without its n first elements If this array has less than n elements, the empty array is returned.
override def dropWhile (p : (A) => Boolean) : Array[A]
Returns the longest suffix of this array whose first element does not satisfy the predicate p.
override def elements : Iterator[A]
An iterator returning the elements of this array, starting from 0.
override def filter (p : (A) => Boolean) : Array[A]
Returns an array consisting of all elements of this array that satisfy the predicate p. The order of the elements is preserved.
override def flatMap [B](f : (A) => Iterable[B]) : Array[B]
Applies the given function f to each element of this array, then concatenates the results.
def indices : Array[Int]
Returns an array that contains all indices of this array
def length : Int
The length of the array
override def map [B](f : (A) => B) : Array[B]
Returns the array resulting from applying the given function f to each element of this array.
override def reverse : Array[A]
A array consisting of all elements of this array in reverse order.
override def slice (from : Int, end : Int) : Array[A]
A sub-array of len elements starting at index from
def subArray (from : Int, end : Int) : Array[A]
override def take (n : Int) : Array[A]
Returns an array consisting only over the first n elements of this array, or else the whole array, if it has less than n elements.
override def takeWhile (p : (A) => Boolean) : Array[A]
Returns the longest prefix of this array whose elements satisfy the predicate p.
override def update (i : Int, x : A) : Unit

Update the element at given index.

Indices start a 0; xs.apply(0) is the first element of array xs.

Note the indexing syntax xs(i) = x is a shorthand for xs.update(i, x).

def zip [B](that : Array[B]) : Array[(A, B)]
Returns an array formed from this array and the specified array that by associating each element of the former with the element at the same position in the latter. If one of the two arrays is longer than the other, its remaining elements are ignored.
def zipWithIndex : Array[(A, Int)]
Returns an array that pairs each element of this array with its index, counting from 0.
