Method Details

def length : Int

The length of the array

def apply(i : Int) : T

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).

Parameters: i - the index
Throws: ArrayIndexOutOfBoundsException - if i < 0 or length <= i

def update(i : Int, x : T) : 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).

Parameters: i - the index; x - the value to be written at index i
Throws: ArrayIndexOutOfBoundsException - if i < 0 or length <= i
