\doxysubsection{Detailed Description}
These functions manage iterators on containers. 

These functions allow accessing elements of a container in a generic way, without knowing which container is used (a bit like iterators in the C++ STL). Iterators only allow sequential access (that is, from one element to the next one). For random access, see \mbox{\hyperlink{group__Eina__Accessor__Group}{Accessor Functions}}.

Getting an iterator to access elements of a given container is done through the functions of that particular container. There is no function to create a generic iterator as iterators absolutely depend on the container. This means you won\textquotesingle{}t find an iterator creation function here, those can be found with the documentation of the container type you\textquotesingle{}re using. Though created with container specific functions iterators are always deleted with the same function\+: \mbox{\hyperlink{group__Eina__Iterator__Group_ga50da005e8d26c0a043d0d1c025bc9008}{eina\+\_\+iterator\+\_\+free()}}.

To get the data and iterate, use \mbox{\hyperlink{group__Eina__Iterator__Group_gad870f9b1d5fb8892cb9623ad0e7f75b2}{eina\+\_\+iterator\+\_\+next()}}. To call a function on all the elements of a container, use \mbox{\hyperlink{group__Eina__Iterator__Group_gaff9c1e02361afa3abcede2fd4056d286}{eina\+\_\+iterator\+\_\+foreach()}}.

Definition for the macro to iterate over all elements easily.

\mbox{\texttt{ in,out}}  & {\em itr} & The iterator to use. \\

\mbox{\texttt{ out}}  & {\em data} & Where to store $\ast$ data, must be a pointer support getting its address since $\ast$ \mbox{\hyperlink{group__Eina__Iterator__Group_gad870f9b1d5fb8892cb9623ad0e7f75b2}{eina\+\_\+iterator\+\_\+next()}} requires a pointer to pointer!\\

This macro is a convenient way to use iterators, very similar to \mbox{\hyperlink{group__Eina__List__Group_gac6efafc19f526d916cdb9757240a8773}{EINA\+\_\+\+LIST\+\_\+\+FOREACH()}}.

This macro can be used for freeing the data of a list, like in the following example. It has the same goal as the one documented in \mbox{\hyperlink{group__Eina__List__Group_gac6efafc19f526d916cdb9757240a8773}{EINA\+\_\+\+LIST\+\_\+\+FOREACH()}}, but using iterators\+:

\begin{DoxyNote}{Note}
This example is not optimal algorithm to release a list since it will walk the list twice, but it serves as an example. For optimized version use \mbox{\hyperlink{group__Eina__List__Group_gae27a2c686a0a11693f9b06957c9bba83}{EINA\+\_\+\+LIST\+\_\+\+FREE()}}
\end{DoxyNote}
\begin{DoxyWarning}{Warning}
The order in which the elements will be traversed depends on the underlying container and {\bfseries{shouldn\textquotesingle{}t}} be relied upon.

unless explicitly stated in functions returning iterators, do not modify the iterated object while you walk it, in this example using lists, do not remove list nodes or you might crash! This is not a limitation of iterators themselves, rather in the iterators implementations to keep them as simple and fast as possible.
