BidirectionalIterator<java.lang.Boolean>, BooleanBidirectionalIterator, BooleanIterator, BooleanListIterator, ObjectBidirectionalIterator<java.lang.Boolean>, ObjectIterator<java.lang.Boolean>, java.io.Serializable, java.lang.Cloneable, java.util.Iterator<java.lang.Boolean>, java.util.ListIterator<java.lang.Boolean>

Enclosing class:

BooleanIterators

public static class BooleanIterators.EmptyIterator
extends AbstractBooleanListIterator
implements java.io.Serializable, java.lang.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.
