Method Detail

transform

public static Query transform(Query query,
                              Map<Var,? extends Node> substitutions)

Transform a query based on a mapping from Var variable to replacement Node.

transformQuery

public static Query transformQuery(Query query,
                                   Map<String,? extends RDFNode> substitutions)

Transform a query based on a mapping from variable name to replacement RDFNode (a Resource (or blank node) or a Literal).

transform

public static Query transform(Query query,
                              ElementTransform transform,
                              ExprTransform exprTransform)

Transform a query using ElementTransform and ExprTransform. It is the responsibility of these transforms to transform to a legal SPARQL query.
