                                 Collection<org.apache.jena.rdf.model.RDFNode> results)

addValueNodes

public static void addValueNodes(org.apache.jena.rdf.model.RDFNode focusNode,
                                 org.apache.jena.rdf.model.Resource path,
                                 Collection<org.apache.jena.rdf.model.RDFNode> results)

appendPath

public static void appendPath(StringBuffer sb,
                              org.apache.jena.rdf.model.Resource path)

Renders a given path into a given StringBuffer, using the prefixes supplied by the Path's Model.

Parameters:

sb - the StringBuffer to write into

path - the path resource

clonePath

public static org.apache.jena.rdf.model.Resource clonePath(org.apache.jena.rdf.model.Resource path,
                                                           org.apache.jena.rdf.model.Model targetModel)

createPath

public static org.apache.jena.rdf.model.Resource createPath(org.apache.jena.sparql.path.Path path,
                                                            org.apache.jena.rdf.model.Model model)

Creates SHACL RDF triples for a given Jena Path (which may have been created using getJenaPath).

Parameters:

path - the Jena Path

model - the Model to create the triples in

Returns:

the (root) Resource of the SHACL path

getJenaPath

public static Object getJenaPath(String string,
                                 org.apache.jena.rdf.model.Model model)
                          throws org.apache.jena.query.QueryParseException

Attempts to parse a given string into a Jena Path. Throws an Exception if the string cannot be parsed.

Parameters:

string - the string to parse

model - the Model to operate on (for prefixes)

Returns:

a Path or a Resource if this is a URI

Throws:

org.apache.jena.query.QueryParseException

getPathString

public static String getPathString(org.apache.jena.rdf.model.Resource path)
