Method Detail

close
public void close()
Description copied from interface:CloseableIterationCloses this iteration, freeing any resources that it is holding. If the iteration has already been closed then invoking this method has no effect.- Specified by:
closein interfaceAutoCloseable- Specified by:
closein interfaceCloseableIteration<BindingSet,QueryEvaluationException>
-
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.)- Specified by:
hasNextin interfaceIteration<BindingSet,QueryEvaluationException>- Specified by:
hasNextin interfaceQueryResult<BindingSet>- Returns:
trueif the iteration has more elements.
-
next
public BindingSet next()
Description copied from interface:QueryResultReturns the next element in the query result.- Specified by:
nextin interfaceIteration<BindingSet,QueryEvaluationException>- Specified by:
nextin interfaceQueryResult<BindingSet>- Returns:
- the next element in the query result.
-
remove
public void remove()
Description copied from interface:IterationRemoves from the underlying collection the last element returned by the iteration (optional operation). This method can be called only once per call to next.- Specified by:
removein interfaceIteration<BindingSet,QueryEvaluationException>
-
getBindingNames
public List<String> getBindingNames() throws QueryEvaluationException
Description copied from interface:TupleQueryResultGets the names of the bindings, in order of projection.- Specified by:
getBindingNamesin interfaceTupleQueryResult- Returns:
- The binding names, in order of projection.
- Throws:
QueryEvaluationException
