Storage Class Reference

Storage package is used to write and read persistent objects. These objects are read and written by a retrieval or storage algorithm (Storage_Schema object) in a container (disk, memory, network ...). Drivers (FSD_File objects) assign a physical container for data to be stored or retrieved. The standard procedure for an application in reading a container is the following: More...

Detailed Description

Storage package is used to write and read persistent objects. These objects are read and written by a retrieval or storage algorithm (Storage_Schema object) in a container (disk, memory, network ...). Drivers (FSD_File objects) assign a physical container for data to be stored or retrieved. The standard procedure for an application in reading a container is the following:

• open the driver in reading mode,
• call the Read function from the schema, setting the driver as a parameter. This function returns an instance of the Storage_Data class which contains the data being read,
• close the driver. The standard procedure for an application in writing a container is the following:
• open the driver in writing mode,
• create an instance of the Storage_Data class, then add the persistent data to write with the function AddRoot,
• call the function Write from the schema, setting the driver and the Storage_Data instance as parameters,
• close the driver.
