Standard properties in the @baseclass class

The standard properties in the @baseclass class are by definition available for every object in the Pega Platform system. This table identifies several of these, in alphabetical order ignoring the first two characters of the name.

Many are optional or not applicable to specific applications. A few are essential control elements present in every instance of every class. Certain properties are maintained by internal facilities and are read-only to applications.
