object.h
|
|
|
|
Provides a primitive object framework to back objects
|
|
in higher level languages of QF so that they can share
|
|
objects. For example, Ruamoko and GIB would be able to
|
|
pass String objects to each other, even if the higher
|
|
-level implementations of String in each language differ.
