public class SparqlTripleSource extends TripleSourceBase implements TripleSource
This triple source supports the SparqlEndpointConfiguration for defining whether ASK queries are to be used
for source selection.
The query result of getStatements(String, BindingSet, FilterValueExpr, QueryInfo) is wrapped in a
ConsumingIteration to avoid blocking behavior..
