public interface IterableCollection<T>
extends java.util.Collection<T>
Collection view of an Iterable, requiring only Iterable.iterator() to be implemented in
order to present a full Collection. This interface is thus a functional interface of Iterable's
Iterable.iterator() method. All methods are implemented through Iterator traversal of the underlying
Iterable. All methods are supported except add(Object) and addAll(Collection).| Modifier and Type | Method and Description |
