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

Method Detail

execEvaluated

public final QueryIterator execEvaluated(Binding binding,
                          PropFuncArg argSubject,
                          Node predicate,
                          PropFuncArg argObject,

execEvaluated

public abstract QueryIterator execEvaluated(Binding binding,
                          Node subject,
                          Node predicate,
                          Node object,
                          ExecutionContext execCxt)

Parameters:

binding - Current solution from previous query stage

subject - Node in subject slot, after substitution if a bound variable in this binding

predicate - This predicate

object - Node in object slot, after substitution if a bound variable in this binding

execCxt - Execution context

Returns:

QueryIterator
