Enclosing class:
FloatIterators

public static class FloatIterators.EmptyIterator
extends AbstractFloatListIterator
implements Serializable, Cloneable

A class returning no elements and a type-specific iterator interface.

This class may be useful to implement your own in case you subclass a type-specific iterator.
