/**

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