public class CollectionTransformer<In,Out>
extends Object
implements ETransformer<Iterable<In>,EList<Out>>

CollectionTransformer enables succinct transformation of collections of objects utilising the ETransformer pattern. CollectionTransformers are stateless and can be instantiated directly and reused, or for convenience created using the static methods available on ETransformers. On top of the regular from(Iterable) override this class offers another method (from(Object...) which accepts varargs for convenience in invocation.
