Method Details

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 interface TupleQueryResult

Returns:

The binding names, in order of projection.

Throws:

QueryEvaluationException

iterator

public Iterator<BindingSet> iterator()

Specified by:

iterator in interface Iterable<BindingSet>

Specified by:

iterator in interface QueryResult<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 interface AutoCloseable

Specified by:

close in interface CloseableIteration<BindingSet,QueryEvaluationException>

Throws:

QueryEvaluationException

hasNext

public boolean hasNext()
                throws QueryEvaluationException

Description copied from interface: QueryResult

Returns true if the query result has more elements. (In other words, returns true if QueryResult.next() would return an element rather than throwing a NoSuchElementException.)

Specified by:

hasNext in interface Iteration<BindingSet,QueryEvaluationException>

Specified by:

hasNext in interface QueryResult<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 interface Iteration<BindingSet,QueryEvaluationException>

Specified by:

next in interface QueryResult<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 interface Iteration<BindingSet,QueryEvaluationException>

Throws:

QueryEvaluationException

stream

public Stream<BindingSet> stream()

Description copied from interface: QueryResult

Convert the result elements to a Java Stream. 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 interface CloseableIteration<BindingSet,QueryEvaluationException>

Specified by:

stream in interface Iteration<BindingSet,QueryEvaluationException>

Specified by:

stream in interface QueryResult<BindingSet>

Returns:

stream a Stream of query result elements.

forEach

public void forEach(Consumer<? super BindingSet> action)

Specified by:

forEach in interface Iterable<BindingSet>

spliterator

public Spliterator<BindingSet> spliterator()

Specified by:

spliterator in interface Iterable<BindingSet>
