public class SHACLSPARQLARQFunction
extends SHACLARQFunction

An ARQ function that is based on a sh:SPARQLFunction. There are two ways of declaring such functions: - as sh:Function (similar to SPIN functions) - from constraint components that point at sh:SPARQLAskValidators This class has two constructors for those two cases.

Constructor Details

SHACLSPARQLARQFunction

public SHACLSPARQLARQFunction(SHConstraintComponent component,
 org.apache.jena.rdf.model.Resource askValidator)

Constructs a new SHACLSPARQLARQFunction based on a given sh:ConstraintComponent and a given validator (which must be a value of sh:nodeValidator, sh:propertyValidator etc.

Parameters:

component - the constraint component (defining the sh:parameters)

askValidator - the sh:SPARQLAskValidator resource

SHACLSPARQLARQFunction

public SHACLSPARQLARQFunction(SHSPARQLFunction shaclFunction)

Constructs a new SHACLSPARQLARQFunction based on a given sh:Function. The shaclFunction must be associated with the Model containing the triples of its definition.

Parameters:

shaclFunction - the SHACL function
