Method Detail

next

public AtomicValue next()

Get the next item.

Specified by:

next in interface SequenceIterator

Specified by:

next in interface AtomicIterator

Specified by:

next in interface UnfailingIterator

Overrides:

next in class EmptyIterator

Returns:

the next item. For the EmptyIterator this is always null.

getAnother

public EmptyIterator.OfAtomic getAnother()

Get another iterator over the same items, positioned at the start.

Specified by:

getAnother in interface AtomizedValueIterator

Specified by:

getAnother in interface SequenceIterator

Specified by:

getAnother in interface AtomicIterator

Specified by:

getAnother in interface UnfailingIterator

Overrides:

getAnother in class EmptyIterator

Returns:

another iterator over an empty sequence (in practice, it returns the same iterator each time)
