Method Detail

toIntArray

public int[] toIntArray()

toArray

public static int[] toArray(List<Integer> integers)

Converts a list of Integer objects to an array of primitive ints.

Parameters:

integers - List of Integer objects

Returns:

Array of primitive ints

asList

public static List<Integer> asList(int[] args)

Returns a list backed by an array of primitive int values.

The behavior is analogous to Arrays.asList(Object[]). Changes to the list are reflected in the array. The list cannot be extended.

Parameters:

args - Array of primitive int values

Returns:

List backed by array

asImmutable

public ImmutableIntList asImmutable()
