Class 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).
