Ciao Christian,
This does not seem a good solution for my problem.
Method must be defined inside the object during the creation and should be
only a reference to a function assigned to the method values at object
creation. It must not be the function itself. I want to be able to:
- change the function and have it changed in all the objects created with
reference to this function
- have the 4/5 same instances of code in memory for 10.000 object which uses
the same code.
Example:
REBOL [
Tittle: "Array experiments"
version: "0.1"
]
func1: func [func_obj] [print func_obj/v1]
func2: func [func_obj] [print func_obj/v2]
tipo1: make object! [
v1: "val1"
v2: "val2"
f1: []
f2: func [obj] [print obj/v2] ;not meaningful
f3: does [f1 self]
f4: does [func1 self]
]
obj1: make tipo1
obj2: make tipo1 [f1: :func1]
I want to write, somewhere after obj2 creation, this line of code:
func1: :func2
And have f1 changed inside obj2 and f3 executing func2 instead of func1.
f4 seems to be a perfect solution but I don't know ho to change it to
f4: does [<my_preferred_function_for_this_object> self]
during the object creation.
Example:
obj2: make tipo1 [f4: ***********]
where ************ could be, in this particular situation: "does
[func2 self]"

One easy solution is to hand over the object itself to the functions as
an argument:
>> proto: make object! [value: none]
>> object-a: make proto [value: 1]
>> object-b: make proto [value: 2]
>> method: func [object] [probe object/value]
>> method object-a
1
== 1
>> method object-b
2
== 2
