Hi R-community,
I'm very busy with a software project which I would like to development
completely with R.oo. Many of the object oriented aspects that I already
know from Java development seems to be in place with this library.
But...there is something that I'm really missing... *the super method call*
Just a little example that shall demonstrate what I mean:
Image we have the following class hierachie that I graped from another post
- thx to YuriWerewolf ;-).
*ClassA*
setConstructorS3("ClassA", function(A) {
extend(Object(), "ClassA",
.size = A
);
})
setMethodS3("print", "ClassA", function(this,...) {
print(paste('Class A:',this$.size));
})
*ClassB (inherits ClassA)*
setConstructorS3("ClassB", function(B=15) {
extend(ClassA(), "ClassB",
.something = B
);
})
# Now I would like to extend the behavior of the super$print() method. It is
not intended to
# get rid of the super$mehtods logic but to execute it too and add some more
specific commands.
setMethodS3("print", "ClassB", function(this,...) {
/super$print()/ # this kind of call is missing
print(paste('Class B:',this$.something));
})
Hopefully I could make clear what I mean.
Thanks and best regards,
Adam L.
