closein interfaceCloseableIteration<Statement>
-
hasNext
public boolean hasNext()
Description copied from interface:QueryResultReturnstrueif the query result has more elements. (In other words, returnstrueifQueryResult.next()would return an element rather than throwing aNoSuchElementException.)
-
next
public Statement next()
Description copied from interface:QueryResultReturns the next element in the query result.
-
getNamespaces
public Map<String,String> getNamespaces() throws QueryEvaluationException
Description copied from interface:GraphQueryResultRetrieves relevant namespaces from the query result.

- a Map<String, String> object containing (prefix, namespace) pairs.
