Workplace objects are icons representative of physical objects which users deal with in the Workplace. A Workplace object is implemented as an instance of a Workplace object class. Workplace object classes are System Object Model (SOM) object classes which are descendants of the predefined Workplace object class, WPObject. For more information about SOM object classes, see System Object Model Guide and Reference.

All Workplace objects are descendants of a Workplace object storage class. Workplace storage object classes are responsible primarily for storing and retrieving object class data for instances of objects which are descendants (subclasses) of that storage class.

The three predefined Workplace object storage classes are:

WPAbstract

Storage class for objects stored in the user profile (OS2.INI)
WPFileSystem
Storage class for objects stored as files in the file system
WPTransient
Storage class for non-persistent objects.
