[Zorba-coders] [Bug 867262] Re: Ext func arg item seq can not be consumed 2 times
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.

[Zorba-coders] [Bug 867262] Re: Ext func arg item seq can not be consumed 2 times
Gabriel, would it be ok with your use case if instead of calling getIterator() a second time, you reused the same iterator? Basically, the code would look something like this: Item item; Iterator_t iter = args[0] ->getIterator( ); iter->open(); iter->next(item); iter->close(); // iter = args[0] ->getIterator( ); iter->open(); iter->next(item); iter->close(); The only difference between the above code and your example is that I have commented-out the 2nd call to getIterator(). In general, it doesn't make sense to have more than one iterator on a ExtFuncArgItemSequence, unless the sequence is materialized, and then you would get a performance hit. -- 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.
