[erlang-questions] parameterized modules and OO
Wed May 30 14:10:08 CEST 2007
I just read the very cool paper about "parameterized modules"
and cooked up a little experimental OO framework. This makes
it possible to write code, such as:
M = mstring:new("hello").
M:len(). => 5
M:append(" world"). => "hello world"
M:len() => 11
This code is using an ETS table to store the state, i.e boring...
(code can be found here: http://www.tornkvist.org/gitweb
look for the mobject project)
So I was thinking, would it be possible for a parameterized module
to modify its own module attributes ?
module_info(store, module_info(store) ++ Str).
This way, the ETS table could go away and we have a self-contained
object. One should even be able to add a simple inheritance mechanism.
So would this be possible to add without too much hassle ?
(NB: I'm not saying this is good or bad, I'm not even proposing
this, I'm just curious to hear if it would be easy/hard/impossible to
add this functionality.)
