All Implemented Interfaces:

Iterator

public class SemWebIterator
extends Object
implements Iterator

A Semantic Web Client Iterator which is returned from the find(TripleMatch pattern) method of the SemWebClientImpl. If the hasNext() method is called and there are no matching triples the Interator waits until new graphs are retrieved. If the retrieval is finished and there are no more matching triples the hasNext() method returns false.
