I am trying to find references to articles that deal with the problems of
dealing with and representing multiple inheritence in a compiled program.
I am also interested in any articles that deal with how large typical
object-oriented classes get (ie. how many features/routines does a typical
class define, how many classes are typically inherited from, how deep the
inheritence tree gets, how often a feature is renamed).
The only reference I have currently is "An Object Addressing Mechanism for
Statically Typed Languages with Multiple Inheritence" by R.C.H. Conner,
A. Dearle, R. Morrison, and A.L. Brown.
The reason for this request is that I am doing a project evaluating
modification of the "map" system presented in the above article, and would
like to compare the original "map" system and the modified one to any
other methods out there.
For example, assuming I had the following class structure:
B.c C.d (renamed from A's b)
D.g (renamed from C's c)
where: class A has the features a,b
class B has the features a,b,c,e
class C has the features a,d,c
class D has the features a,b,c,d,e,f,g
I am trying to find answers to the following questions:
a) What other schemes are there?
b) How is multiple inheritence handled (this includes what restrictions
the scheme forces on multiple inheritence)?
c) If an object is assigned to a variable that is of an inherited class
type, how is the object changed to allow correct addressing of the
fields/features/routines (eg. an object x of class D is assigned
to variable y of class C, how is y.c handled)?
d) Approximately how long would it take to do the assignment and/or
find a given feature in a variable?
e) How much space does the cheme take up?
Any references to articles would be greatly appreciated!
