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.

In addition to iterator functions, each data type also owns a set of macros that provide the iterators, such as ``FOREACH`` or ``REVERSE_FOREACH``.
