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:
- java.lang.Iterable<E>, ListIterable<E>
public class SingleElementListIterable<E>
- extends java.lang.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)
.
