Data Structures
class	Storage_Schema
	Root class for basic storage/retrieval algorithms. A Storage_Schema object processes: writing of a set of persistent data into a container (store mechanism), reading of a container to extract all the contained persistent data (retrieve mechanism). A Storage_Schema object is based on the data schema for the persistent data of the application, i.e.: the list of all persistent objects which may be known by the application, the organization of their data; a data schema knows how to browse each persistent object it contains. During the store or retrieve operation, only persistent objects known from the data schema can be processed; they are then stored or retrieved according to their description in the schema. A data schema is specific to the object classes to be read or written. Tools dedicated to the environment in use allow a description of the application persistent data structure. Storage_Schema algorithms are called basic because they do not support external references between containers. More...
