fr.mines_stetienne.ci.sparql_generate.iterator.SPARQLExtIteratorFunction

All Implemented Interfaces:

IteratorFunction

public class SPARQLExtIteratorFunction
extends IteratorStreamFunctionBase

Iterator function iter:call-select takes as input a IRI to a SPARQL-Select document, runs it on the current Dataset, and binds the given variables to the output of the select query, in order.

• Param 1: (select) is the IRI to a SPARQL-Select document

Multiple variables may be bound: variable n is bound to the value of the n^th project variable of the select query.
