Method Details

to

<T> ExtendedIterable<T> to(Function<E,T> mapper)

Type Parameters:

T - is the type of the elements the given mapper maps from the elements of the current Mappable.

Parameters:

mapper -

Returns:

a new ExtendedIterable with the elements the given mapper maps from the elements of the current Mappable.

Throws:

RuntimeException - if the given mapper is null

RuntimeException - if one of the elements of the current Mappable is null.

toMultiples

<T> ExtendedIterable<T> toMultiples(Function<E, ExtendedIterable<T>> multipleMapper)

Type Parameters:

T - is the type of the elements of the ExtendedIterables the given multipleMapper maps from the elements of the current Mappable.

Parameters:

multipleMapper -

Returns:

a new ExtendedIterable with the elements of the ExtendedIterables the given multipleMapper maps from the elements of the current Mappable.

Throws:

RuntimeException - if the given multipleMapper is null

RuntimeException - if one of the elements of the current Mappable is null.

toNumbers

<N extends Number> ExtendedIterable<N> toNumbers(Function<E,N> numberMapper)

Type Parameters:

N - is the type of the Numbers the given numberMapper maps from the elements of the current Mappable.

Parameters:

numberMapper -

Returns:

a new ExtendedIterable with the Numbers the given numberMapper maps from the elements of the current Mappable. Maps null elements to 0.0.

Throws:

RuntimeException - if the given numberMapper is null.

toStrings

ExtendedIterable<String> toStrings()

Returns:

a new ExtendedIterable with the String representations of the elements of the current ExtendedIterable.

toWithOneBasedIndex

<T> ExtendedIterable<T> toWithOneBasedIndex(BiFunction<Integer,E,T> mapper)

Type Parameters:

T - is the type of the elements the given mapper maps from the elements of the current Mappable and from the one-based index of these elements.

Parameters:

mapper -

Returns:

a new ExtendedIterable with the elements the given mapper maps from the elements of the current Mappable and from the one-based index of these elements.

Throws:

RuntimeException - if the given mapper is null

RuntimeException - if one of the elements of the current Mappable is null.
