Method Summary

Modifier and Type	Method and Description
public static < the object type T> Transformer<T, T>	Returns: the `chained` transformer chainedTransformer(final Transformer<? super T, ? extends T>... the transformers to chain, copied, no nulls transformers) Factory method that performs validation and copies the parameter array.
public static < the object type T> Transformer<T, T>	Returns: the `chained` transformer chainedTransformer(final Collection<? extends Transformer<? super T, ? extends T>> a collection of transformers to chain transformers) Create a new Transformer that calls each transformer in turn, passing the result into the next transformer.
public Transformer<? super T, ? extends T>[]	Returns: a copy of the transformers getTransformers() Gets the transformers.
public T	Returns: the transformed result transform(T the input object passed to the first transformer object) Implements org.apache.commons.collections4.Transformer.transform. Transforms the input to result via each decorated transformer

chainedTransformer	back to summary
public static <T> Transformer<T, T> chainedTransformer(final Collection<? extends Transformer<? super T, ? extends T>> transformers) Create a new Transformer that calls each transformer in turn, passing the result into the next transformer. The ordering is that of the iterator() method on the collection. Parameters <T> the object type transformers:Collection<? extends Transformer<? super T, ? extends T>> a collection of transformers to chain Returns:Transformer<T, T> the `chained` transformer Exceptions NullPointerException: if the transformers collection is null if any transformer in the collection is null

public static <T> Transformer<T, T> chainedTransformer(final Collection<? extends Transformer<? super T, ? extends T>> transformers)

Create a new Transformer that calls each transformer in turn, passing the result into the next transformer. The ordering is that of the iterator() method on the collection.

Parameters

<T>: the object type
transformers:Collection<? extends Transformer<? super T, ? extends T>>: a collection of transformers to chain

Returns:Transformer<T, T>

the chained transformer

Exceptions

NullPointerException:

if the transformers collection is null
if any transformer in the collection is null
