withPrefixes

public static String withPrefixes(String str,
                                  org.apache.jena.rdf.model.Resource executable)

Gets a parsable SPARQL string based on a fragment and prefix declarations. Depending on the setting of the flag useGraphPrefixes, this either uses the prefixes from the Jena graph of the given executable, or strictly uses sh:prefixes.

Parameters:

str - the query fragment (e.g. starting with SELECT)

executable - the sh:SPARQLExecutable potentially holding the sh:prefixes

Returns:

the parsable SPARQL string
