Class RemoteSparql10QueryBuilder

java.lang.Object

com.bigdata.rdf.sparql.ast.service.RemoteSparql10QueryBuilder

All Implemented Interfaces:

IRemoteSparqlQueryBuilder

public class RemoteSparql10QueryBuilder
extends Object
implements IRemoteSparqlQueryBuilder

Utility class constructs a valid SPARQL query for a remote SPARQL 1.0 end point (no BINDINGS clause and does not support SELECT expressions or BIND()).

Note: This class functions by adding FILTER (sameTerm(?var,bound-value)) instances for each variable binding inside of the SERVICE's graph pattern.

Note: Unlike the RemoteSparql11QueryBuilder, this class does not need to impose a correlation on variables which are bound to the same blank node since we can communicate blank nodes within a FILTER.
