\subsection{Detailed Description}
This class a basic iterator class for objects. 

Call \mbox{\hyperlink{class_qore_1_1_hash_iterator_ae1c8221cd1002edbb93ec41a333900ae}{Object\+Iterator\+::next()}} to iterate through the object; do not use the iterator if \mbox{\hyperlink{class_qore_1_1_hash_iterator_ae1c8221cd1002edbb93ec41a333900ae}{Object\+Iterator\+::next()}} returns \mbox{\hyperlink{group__boolean__constants_ga9da2b9a8003cd3788e48305f8a00540f}{False}}. An object can be iterated in reverse order by calling \mbox{\hyperlink{class_qore_1_1_hash_iterator_a9df83a19c89100056c875b2ca40f6ed3}{Object\+Iterator\+::prev()}} instead of \mbox{\hyperlink{class_qore_1_1_hash_iterator_ae1c8221cd1002edbb93ec41a333900ae}{Object\+Iterator\+::next()}}

\begin{DoxyNote}{Note}

\begin{DoxyItemize}
\item In general, the \mbox{\hyperlink{class_qore_1_1_object_iterator}{Object\+Iterator}} class is not designed to be accessed from multiple threads; it was created without locking for fast and efficient use when used from a single thread. For methods that would be unsafe to use in another thread, any use of such methods in threads other than the thread where the constructor was called will cause an {\ttfamily I\+T\+E\+R\+A\+T\+O\+R-\/\+T\+H\+R\+E\+A\+D-\/\+E\+R\+R\+OR} to be thrown.
