I think it's fine to restrict the API to only allow one iterator at a time. If the user has a use case that requires two active iterators at a time, he should think about his use case and eventually materialize in his code.
I'm going to approve the merge proposal. -- You received this bug notification because you are a member of Zorba Coders, which is the registrant for Zorba. https://bugs.launchpad.net/bugs/867262 Title: Ext func arg item seq can not be consumed 2 times Status in Zorba - The XQuery Processor: New Bug description: If one tried to consume an external function argument item sequence 2 times, the 2nd time no more item is returned: next returns false and the item is NULL. To reproduce, take any external module and in the "evaluate" implementation of a function do the following (make sure that the function receives a non non-empty sequence as the first parameter): Item item; Iterator_t iter = args->getIterator(); iter->open(); iter->next(item); iter->close(); // item is valid here iter = args->getIterator(); iter->open(); iter->next(item); iter->close(); // item is NULL here To manage notifications about this bug go to: https://bugs.launchpad.net/zorba/+bug/867262/+subscriptions -- Mailing list: https://launchpad.net/~zorba-coders Post to : email@example.com Unsubscribe : https://launchpad.net/~zorba-coders More help : https://help.launchpad.net/ListHelp
