SystemEnvironment is an abstract base class for 'environments'
|
|
63 |
An 'environment' is an object that keeps track of classes and
|
|
64 |
methods and can be asked for those.
|
|
65 |
|
|
66 |
Its protocol is polymorph with protocol of Smalltalk and NameSpace
|
|
67 |
classes. I.e., wherever s code uses Smalltalk or NameSpace subclass to
|
|
68 |
get list of classes and/or methods ic can be interchanged with an
|
|
69 |
custom instance SystemEnvironment.
