All, I am looking at extending the multiple inheritance example
in “Programming In Lua” (ch. 16.3). I would like to support
method chaining, i.e. at the point marked by a call to “next” , the
next shadowed method on a “next-path” is searched and, when it is
found, it is mixed into the execution of the current method (i.e. executed in
the same scope and then execution of the original method continues). This is a
more generic version of a call to super() in a Java constructor. The idea for
this is taken from XOTCL http://media.wu-wien.ac.at/. My initial though is to have a root Object that handles the
message “next” (I would be aiming for the “next-path”
to be predictable (breadth first search), but any thoughts from more
experienced lua programmers would be appreciated. Regards, Martin |
