public CleanerTupleQueryResult(TupleQueryResult delegate,
 ConcurrentCleaner cleaner)

Method Details

close

public void close()

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>

hasNext

public boolean hasNext()

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.

next

public BindingSet next()

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.

remove

public void remove()

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>

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
