Method Detail

getBindingNames

public List<String> getBindingNames()
                             throws StoreException

Description copied from interface: TupleResult

Gets the names of the bindings, in order of projection.

Specified by:

getBindingNames in interface TupleQueryResult

Specified by:

getBindingNames in interface TupleResult

Returns:

The binding names, in order of projection.

Throws:

StoreException

close

public void close()
           throws StoreException

Description copied from interface: Cursor

Closes this cursor, freeing any resources that it is holding. If the cursor has already been closed then invoking this method has no effect. After closing a cursor, any subsequent calls to Cursor.next() will return null.

Note to implementors: this method is also used to abort long running evaluations. It should be implemented in such a way that it can be called concurrently with Cursor.next() and that it stops evaluation as soon as possible. Calls to Cursor.next() that are already in progress are allowed to still return results, but after returning from Cursor.close() , the cursor must not produce any more results.

Specified by:

close in interface Cursor<BindingSet>

Throws:

StoreException

hasNext

public boolean hasNext()
                throws StoreException

Specified by:

hasNext in interface Result<BindingSet>

Throws:

StoreException

next

public BindingSet next()
                throws StoreException

Description copied from interface: Cursor

Returns the next element from this cursor.

Specified by:

next in interface Cursor<BindingSet>

Returns:

the next element from this cursor, or null if the cursor has no more elements.

Throws:

StoreException

singleResult

public BindingSet singleResult()
                        throws StoreException

Specified by:
