Data Structures
class	Storage_Data
	A picture memorizing the data stored in a container (for example, in a file). A Storage_Data object represents either: persistent data to be written into a container, or persistent data which are read from a container. A Storage_Data object is used in both the storage and retrieval operations: Storage mechanism: create an empty Storage_Data object, then add successively persistent objects (roots) to be stored using the function AddRoot. When the set of data is complete, write it to a container using the function Write in your Storage_Schema storage/retrieval algorithm. Retrieval mechanism: a Storage_Data object is returned by the Read function from your Storage_Schema storage/retrieval algorithm. Use the functions NumberOfRoots and Roots to find the roots which were stored in the read container. The roots of a Storage_Data object may share references on objects. The shared internal references of a Storage_Data object are maintained by the storage/retrieval mechanism. Note: References shared by objects which are contained in two distinct Storage_Data objects are not maintained by the storage/retrieval mechanism: external references are not supported by Storage_Schema algorithm More...
