Class PFuncSimpleAndList

java.lang.Object

org.apache.jena.sparql.pfunction.PropertyFunctionBase

org.apache.jena.sparql.pfunction.PropertyFunctionEval

org.apache.jena.sparql.pfunction.PFuncSimpleAndList

All Implemented Interfaces:

PropertyFunction

Direct Known Subclasses:

concat, strSplit

public abstract class PFuncSimpleAndList
extends PropertyFunctionEval

Common, simple case:

• subject argument is not a list
• object is a list
• call the implementation with one binding at a time

Method Detail

execEvaluated

public QueryIterator execEvaluated(Binding binding,
                                   PropFuncArg argSubject,
                                   Node predicate,
                                   PropFuncArg argObject,
                                   ExecutionContext execCxt)

Specified by:

execEvaluated in class PropertyFunctionEval

Parameters:

binding - Current solution from previous query stage

argSubject - PropFuncArg, after substitution of any bound variables in this binding

predicate - This predicate

argObject - PropFuncArg, after substitution of any bound variables in this binding

execCxt - Execution context

Returns:

QueryIterator

execEvaluated

public abstract QueryIterator execEvaluated(Binding binding,
