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.

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.
