Method Detail

iterator

public java.util.Iterator<java.util.Collection<Q>> iterator()

Description copied from interface: QueueItemProvider

Generally returns this. QueueItemProviders are not generally reusable/resettable since the underlying message source will often not be reversible. Mashing the two interfaces together simplifies implementations a bit, and also supports any typical Iterable usage.
