Eina provides a set of iterator functions to manipulate data types, such as arrays.
These functions allow access to container elements in a generic way, without knowing which container is used (similar to iterators in the C++ STL). Iterators only allow sequential access (that is, from one element to the next one). For random access, Eina provides 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. Note that
all iterators, regardless of the container type, are always deleted with the
To get the data and iterate, use the
eina_iterator_next() function. To
call a function on every single element of a container, use the
In addition to iterator functions, each data type also owns a set of macros
that provide the iterators, such as
