Using Caché Objects - InterSystems Documentation

2. It resolves inheritance—it determines which methods, properties, and other class members
are inherited from super classes. It stores this inheritance information into the Class
Dictionary for later reference.
3. For persistent and serial classes, it determines the storage structure needed to store objects
in the database and creates the necessary runtime information needed for the SQL representation
of the class.
4. It executes any method generators defined (or inherited) by the class.
5. It creates one or more routines that contain the runtime code for the class. The Class
Compiler will group methods according to language (Caché ObjectScript and Basic) and
generates separate routines, each containing methods of one language or the other.
If you specify the “Keep Generated Source” option with the Class Compiler, you can
view the source for the routines using the View Other command within Studio.
6. It compiles all of the generated routines into executable code.
7. It create a class descriptor. This is a special data structure (stored as a routine) that contains
all the runtime dispatch information needed to support a class (names of properties,
locations of methods, etc.).
There are several ways to invoke the Class Compiler:
• From within Caché Studio using the option in the Build menu.
• From the Caché command line (terminal) using the Compile method of the %SYSTEM.OBJ
object:
Do $System.OBJ.Compile("MyApp.MyClass")
Class Compilation
Note that if you use SQL DDL statements to create a table, the Class Compiler will be automatically
invoked to compile the persistent class corresponding to the table.
