Common, simple case:

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

execEvaluated

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

execEvaluated

public abstract QueryIterator execEvaluated(Binding binding,
                          Node subject,
                          Node predicate,
                          PropFuncArg 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 - List in object slot, after substitution if a bound variable in this binding

execCxt - Execution context

Returns:

QueryIterator
