<E>
the type of elements returned by the list iterable's list iterator
Imports
java.util.ListIterator, org.eclipse.persistence.jpa.jpql.tools.utility.iterator.SingleElementListIterator, org.eclipse.persistence.jpa.jpql.utility.iterable.ListIterable
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: java.util.Collections#singletonList(Object).
