Streamable (Spring Data Core 2.0.0.M2 API)

All Superinterfaces:

Iterable<T>

All Known Subinterfaces:

Page<T>, Slice<T>

All Known Implementing Classes:

DefaultParameters, GeoPage, PageImpl, Parameters, PartTree, PartTree.OrPart, PersistentEntities, PropertyPath, Revisions, SliceImpl

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface Streamable<T>
extends Iterable<T>
```
Simple interface to ease streamability of Iterables.
