Method Detail
-
getNamespaces
public Map<String,String> getNamespaces() throws QueryEvaluationException
Description copied from interface:GraphQueryResult
Retrieves relevant namespaces from the query result.
The contents of the Map may be modified after it is returned, as the initial return may be performed when the first RDF Statement is encountered.- Specified by:
getNamespaces
in interfaceGraphQueryResult
- Returns:
- a Map<String, String> object containing (prefix, namespace) pairs.
- Throws:
QueryEvaluationException
-
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<Statement,QueryEvaluationException>
- Throws:
QueryEvaluationException
-
hasNext
public boolean hasNext() throws QueryEvaluationException
Description copied from interface:Iteration
Returns true if the iteration has more elements. (In other words, returns true ifIteration.next()
would return an element rather than throwing a NoSuchElementException.)- Specified by:
hasNext
in interfaceIteration<Statement,QueryEvaluationException>
- Returns:
- true if the iteration has more elements.
- Throws:
QueryEvaluationException
-
next
public Statement next() throws QueryEvaluationException
Description copied from interface:Iteration
Returns the next element in the iteration.- Specified by:
next
in interfaceIteration<Statement,QueryEvaluationException>
- Returns:
- the next element in the iteration.
- Throws:
QueryEvaluationException
-
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<Statement,QueryEvaluationException>
- Throws:
QueryEvaluationException
-
stream
public Stream<Statement> stream()
Description copied from interface:Iteration
Convert the results to a Java 8 Stream. If this iteration implements CloseableIteration it should be closed (by calling Stream#close() or using try-with-resource) if it is not fully consumed.- Specified by:
stream
in interfaceIteration<Statement,QueryEvaluationException>
- Returns:
- stream
-
spliterator
public Spliterator<Statement> spliterator()
- Specified by:
spliterator
in interfaceIterable<Statement>
