persistent class %Library.CompiledClass extends %Library.Persistent

SQL Table Name: %Library.CompiledClass

Note: The class definition classes in the %Library package have been superceded by those in the %Dictionary package.

This class represents a specific, compiled class description contained within the Caché Dictionary. That is, it contains all class members, including those that are inherited from super classes.

Instances of this class are "read only"; to modify class definitions use the non-compiled class definition classes.

For more information on class definition classes, refer to About Class Definition Classes.
