Interface RewritingWrapper

All Superinterfaces:
Wrapper
public interface RewritingWrapper extends Wrapper
This interface captures any type of wrapper that can be used to evaluate SPARQL query patterns by means of query rewriting into a query language supported by the wrapped federation member. More specifically, such a wrapper produces the result for a given SPARQL graph pattern by rewriting it into the query language of the wrapped federation member, requests the result for the rewritten query, and converts the retrieved result back into a SPARQL result (i.e., a sequence of solution mappings).
