com.hp.hpl.jena.sparql.pfunction.PropFuncArg

All Implemented Interfaces:

PrintSerializable, Printable

public class PropFuncArg
extends PrintSerializableBase

Class representing an argument (subject or object position) of a property function. Such an argument can be a graph node (variable, IRI, literal). Blank nodes from the query will be seen as variables. Most implementations will want to work with the property function arguments after substitution from the current binding.
