Class PFuncSimple
java.lang.Object
com.hp.hpl.jena.sparql.pfunction.PropertyFunctionBase
com.hp.hpl.jena.sparql.pfunction.PropertyFunctionEval
com.hp.hpl.jena.sparql.pfunction.PFuncSimple
- All Implemented Interfaces:
- PropertyFunction
- Direct Known Subclasses:
- assign, blankNode, container, PathPropertyFunction, PFuncAssignToObject, PFuncAssignToSubject, str
public abstract class PFuncSimple
- extends PropertyFunctionEval
Common, simple case:
- arguments are not lists
- attempt to put values in for any bound variables
- call the implementation with one binding at a time
execEvaluated
public final QueryIterator execEvaluated(Binding binding,
PropFuncArg argSubject,
com.hp.hpl.jena.graph.Node predicate,
