Method Detail

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<Statement,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<Statement,QueryEvaluationException>

Specified by:

hasNext in interface QueryResult<Statement>

Returns:

true if the iteration has more elements.

next

public Statement next()

Description copied from interface: QueryResult

Returns the next element in the query result.

Specified by:

next in interface Iteration<Statement,QueryEvaluationException>

Specified by:

next in interface QueryResult<Statement>

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<Statement,QueryEvaluationException>

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 interface GraphQueryResult

Returns:

a Map<String, String> object containing (prefix, namespace) pairs.

Throws:

QueryEvaluationException
