Class adds more functionality to classes; minimum stuff has already
|
|
|
52 |
been defined in Behavior and ClassDescription; this adds naming, categories etc.
|
|
|
53 |
|
|
|
54 |
Also change management and recompilation is defined here (since the superclasses
|
|
|
55 |
do not have enough symbolic information to support compilation).
|
|
|
56 |
|
|
168
|
57 |
For production code, the stc compiler is planned to (optionally) generate classes
|
|
|
58 |
as subclasses of Behavior - to excludes all name, source info etc.,
|
|
68
|
59 |
however, normally all classes are subclasses of Class.
|
|

|
|
|

168
|
70 |
|

71 |
classFilename <String> the file (or nil) where the classes

sources are found
