# To each interface a set of caller functions exist, that take an instance
|
|
# of an object and then in turn call the implementation for the class of
|
|
# this object. If there is none within the class it looks into its
|
|
# parent class and so forth.
|
|
#
|
|
# This is somewhat similar to late binding in real OOP languages, but
|
|
# by far not so elaborated. This is not a real object oriented language
|
|
# and will surely never ever provide all features these have.
|
|
#
|
|
# That said it has proven very usefull for me to orgnize code and prevent
|
|
# code duplication.
