| 30 | + * Memory manager stores a list of generated objects to control them. |
| 31 | + * So container objects always have at least one reference and can't be automatically destroyed. |
| 32 | + * |
| 33 | + * This class is intended to be an userland proxy to memory container object. |
| 34 | + * It's not referenced by memory manager and class destructor is invoked immidiately after gouing |
| 35 | + * out of scope or unset operation. |
| 36 | + * |
| 37 | + * Class also provides Zend_Memory_Container_Interface interface and works as proxy for such cases. |
