/*--------------------------------------------------------------------------
|
|
In SICS there is the to find out what an
|
|
object is capable of at runtime. If this has been done a general
|
|
way to access those capabilities is needed. In order to do all
|
|
this each SICS-object is required to carry an object descriptor
|
|
struct as first parameter in its class/object struct. Additionslly
|
|
it is required to initialize this struct to something sensible.
|
|
|
|
This file defines this struct. Additionally a few functions of
|
|
general use are prototyped.
