EmptyIterable (EclipseLink Hermes Parser 3.0.3 API)

java.lang.Object
- org.eclipse.persistence.jpa.jpql.tools.utility.iterable.EmptyIterable<E>

Type Parameters:

E - the type of elements returned by the iterable's iterator

All Implemented Interfaces:

Serializable, Iterable<E>
```
public final class EmptyIterable<E>
extends Object
implements Iterable<E>, Serializable
```
An EmptyIterable is just that. Maybe just a touch better-performing than Collections.EMPTY_SET since we don't create a new Iterator every time iterator() is called. (Not sure why they do that....)

Since:

2.5

Version:

2.5
