Method Details

toByteArray

public <E> byte[] toByteArray(Iterable<E> iterable,
 int n,
 Function<E,Byte> byteMapper)

The time complexity of this method is O(n) if the given iterable contains n elements.

Specified by:

toByteArray in interface IArrayMapper

Type Parameters:

E - the type of the elements of the given iterable

Parameters:

iterable - the mapped iterable, is considered to be empty when is null

n -

byteMapper -

Returns:

a new array with the first n bytes the given byteMapper maps from the elements of the given iterable, mapping null elements to 0

toDoubleArray

public <E> double[] toDoubleArray(Iterable<E> iterable,
 int n,
 ToDoubleFunction<E> doubleMapper)

The time complexity of this method is O(n) if the given iterable contains n elements.

Specified by:

toDoubleArray in interface IArrayMapper

Type Parameters:

E - the type of the elements of the given iterable

Parameters:

iterable - the mapped iterable, is considered to be empty when is null

n -

doubleMapper -

Returns:

a new array with the first n doubles the given doubleMapper maps from the elements of the given iterable, mapping null elements to 0.0

toIntArray

public <E> int[] toIntArray(Iterable<E> iterable,
 int n,
 ToIntFunction<E> intMapper)

The time complexity of this method is O(n) if the given iterable contains n elements.

Specified by:

toIntArray in interface IArrayMapper

Type Parameters:

E - the type of the elements of the given iterable

Parameters:

iterable - the mapped iterable, is considered to be empty when is null

n -

intMapper -

Returns:

a new array with the first n ints the given intMapper maps from the elements of the given iterable, mapping null elements to 0
