Method Detail
-
getBindingNames
public List<String> getBindingNames() throws QueryEvaluationException
Description copied from interface:TupleQueryResult
Gets the names of the bindings, in order of projection.- Specified by:
getBindingNames
in interfaceTupleQueryResult
- Returns:
- The binding names, in order of projection.
- Throws:
QueryEvaluationException
-
iterator
public Iterator<BindingSet> iterator()
- Specified by:
iterator
in interfaceIterable<BindingSet>
- Specified by:
iterator
in interfaceQueryResult<BindingSet>
-
close
public void close() throws QueryEvaluationException
Description copied from interface:CloseableIteration
Closes 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:
close
in interfaceAutoCloseable
- Specified by:
close
in interfaceCloseableIteration<BindingSet,QueryEvaluationException>
- Throws:
QueryEvaluationException
-
hasNext
public boolean hasNext() throws QueryEvaluationException
Description copied from interface:QueryResult
Returnstrue
if the query result has more elements. (In other words, returnstrue
ifQueryResult.next()
would return an element rather than throwing aNoSuchElementException
.)- Specified by:
hasNext
in interfaceIteration<BindingSet,QueryEvaluationException>
- Specified by:
hasNext
in interfaceQueryResult<BindingSet>
- Returns:
true
if the iteration has more elements.- Throws:
QueryEvaluationException
- if an error occurs while executing the query.
-
next
public BindingSet next() throws QueryEvaluationException
Description copied from interface:QueryResult
Returns the next element in the query result.- Specified by:
next
in interfaceIteration<BindingSet,QueryEvaluationException>
- Specified by:
next
in interfaceQueryResult<BindingSet>
- Returns:
- the next element in the query result.
- Throws:
QueryEvaluationException
- if an error occurs while executing the query.
-
remove
public void remove() throws QueryEvaluationException
Description copied from interface:Iteration
Removes 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:
remove
in interfaceIteration<BindingSet,QueryEvaluationException>
- Throws:
QueryEvaluationException
-
stream
public Stream<BindingSet> stream()
Description copied from interface:QueryResult
Convert the result elements to a JavaStream
. Note that the consumer should take care to close the stream (by calling Stream#close() or using try-with-resource) if it is not fully consumed.- Specified by:
stream
in interfaceCloseableIteration<BindingSet,QueryEvaluationException>
- Specified by:
stream
in interfaceIteration<BindingSet,QueryEvaluationException>
- Specified by:
stream
in interfaceQueryResult<BindingSet>
- Returns:
- stream a
Stream
of query result elements.
-
forEach
public void forEach(Consumer<? super BindingSet> action)
- Specified by:
forEach
in interfaceIterable<BindingSet>
-
spliterator
public Spliterator<BindingSet> spliterator()
- Specified by:
spliterator
in interfaceIterable<BindingSet>
