Interface TupleQueryResult

All Superinterfaces:

public interface TupleQueryResult
extends QueryResult<BindingSet>

A representation of a variable-binding query result as a sequence of BindingSet objects. Each query result consists of zero or more solutions, each of which represents a single query solution as a set of bindings. Note: take care to always close a TupleQueryResult after use to free any resources it keeps hold of.
