noOpTransformer

public static <T> TransformerUtils.Transformer<T,T> noOpTransformer()

toListTransformer

public static <T> TransformerUtils.Transformer<List<T>,Iterable<T>> toListTransformer()

toSetTransformer

public static <T> TransformerUtils.Transformer<Set<T>,Iterable<T>> toSetTransformer()

toSetTransformer

public static <OUT,IN> TransformerUtils.Transformer<Set<OUT>,Iterable<IN>> toSetTransformer(Class<OUT> type)

constant

public static <T,U> TransformerUtils.Transformer<T,U> constant(T value)

configureInPlace

public static <T> TransformerUtils.Transformer<T,T> configureInPlace(Action<? super T> action)

flatTransformEach

public static <OUT,IN> TransformerUtils.Transformer<List<OUT>,Iterable<IN>> flatTransformEach(Transformer<? extends Iterable<OUT>,? super IN> mapper)

Adapts an flat element mapper to transform each elements individually of the collection. The result will apply a proper flatMap algorithm to the provided collection.

Type Parameters:

OUT - output element type resulting from the transform

IN - input element type to transform

Parameters:

mapper - an element mapper

Returns:

a TransformerUtils.Transformer instance to flat transform each the element of an iterable, never null.

transformEach

public static <OUT,IN> TransformerUtils.Transformer<List<OUT>,Iterable<IN>> transformEach(Transformer<? extends OUT,? super IN> mapper)

Adapts an element mapper to transform each elements individually of the collection. The result will apply a proper map algorithm to the provided collection.

Type Parameters:

OUT - output element type resulting from the transform

IN - input element type to transform

Parameters:

mapper - an element mapper

Returns:

a TransformerUtils.Transformer instance to transform each the element of an iterable, never null.

compose

public static <A,B,C> TransformerUtils.Transformer<C,A> compose(Transformer<C,B> g,
                                                                Transformer<? extends B,A> f)
