Class ExprTransformSubstituteWithArgument

java.lang.Object
org.apache.jena.sparql.expr.ExprTransformCopy
org.aksw.jena_sparql_api.algebra.expr.transform.ExprTransformSubstituteWithArgument
All Implemented Interfaces:
org.apache.jena.sparql.expr.ExprTransform
public class ExprTransformSubstituteWithArgument extends org.apache.jena.sparql.expr.ExprTransformCopy
Substitute unary function with its argument - i.e. f(x) -> x Used for example in the r2rml exporter, where explicit string conversions using the 'STR' functions are removed in order to build to r2rml uri template strings: concat('http://foo.bar/baz/', str(?intColumn)) -> "http://foo.bar/baz/{intColumn}"
