To me it looks like <tt style="background: #ebebeb; font-size: 13px;">auto i = new OrPostingIterator(iters); i->docId();</tt> will return 0 and <tt style="background: #ebebeb; font-size: 13px;">i->next()</tt> returns a valid docId. After that <tt style="background: #ebebeb; font-size: 13px;">i->docId();</tt> is also valid.<br />
Is this how iterators work? Naively I would expect <tt style="background: #ebebeb; font-size: 13px;">i->docId();</tt> to be valid after construction or both <tt style="background: #ebebeb; font-size: 13px;">i->docId();</tt> and <tt style="background: #ebebeb; font-size: 13px;">i->next()</tt> to be invalid.</p>
<p>I have to admit, it's very difficult to understand (and I don't, really) what baloo is doing here with all this iterating over vectors of inherited iterator classes, pointer-to-pointer stuff of which some might not even exist. My brain hurts, terribly! All I can presently do is ask some simple questions. Sorry, I'm of no help here. Please take my comments as a device for better understanding and I hope it's not to much of a bother.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R293 Baloo</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D11828">https://phabricator.kde.org/D11828</a></div></div><br /><div><strong>To: </strong>bruns, Baloo, michaelh<br /><strong>Cc: </strong>Frameworks, ashaposhnikov, michaelh, astippich, spoorun, ngraham, bruns, alexeymin<br /></div>
