Examples of org.openrdf.query.GraphQueryResult

org.openrdf.query.GraphQueryResult
A representation of a query result as a sequence of {@link Statement}objects. Each query result consists of zero or more Statements and additionaly carries information about relevant namespace declarations. Note: take care to always close a GraphQueryResult after use to free any resources it keeps hold of. @author jeen
