29 * @brief These functions manage object providing pointer checking
30 * and memory repacking.
32 * Each Eina_Object is in fact only an ID and a generation count. This
33 * make it possible to check if the ID is allocated by checking that it
34 * is inside the boundary limit of the allocated range. The generation
35 * count, give the possibility to check that we use a valid alive pointer
36 * as generation is increased each time an object is allocated/destroyed.
37 * And finally it provide type checking against Eina_Class.
39 * It is also to define link between object, then when father get deleted
40 * all child will get deleted and their respective destructor will be called.
