Constructor Detail

SingleAtomicIterator

public SingleAtomicIterator(T value)

Private constructor: external classes should use the factory method

Parameters:

value - the item to iterate over

Method Detail

getReverseIterator

public SingleAtomicIterator<T> getReverseIterator()

Description copied from interface: ReversibleIterator

Get a new SequenceIterator that returns the same items in reverse order. If this SequenceIterator is an AxisIterator, then the returned SequenceIterator must also be an AxisIterator.

Specified by:

getReverseIterator in interface ReversibleIterator

Overrides:

getReverseIterator in class SingletonIterator<T extends AtomicValue>

Returns:

an iterator over the items in reverse order
