Class SingleElementListIterable<E>

java.lang.Object

org.eclipse.persistence.jpa.jpql.tools.utility.iterable.SingleElementListIterable<E>

Type Parameters:

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

All Implemented Interfaces:

Iterable<E>, ListIterable<E>

public class SingleElementListIterable<E>
extends Object
implements ListIterable<E>

A SingleElementListIterable returns a ListIterator that holds a single element and returns it with the first call to ListIterator.next(), at which point it will return false to any subsequent call to ListIterator.hasNext(). Likewise, it will return false to a call to ListIterator.hasPrevious() until a call to ListIterator.next(), at which point a call to ListIterator.previous() will return the single element.

A SingleElementListIterable is equivalent to the Iterable returned by: Collections.singletonList(Object).
