"Operation" A METHOD. _Notes:_ The object system supports multiple inheritance. An instance can inherit from 0 or more ancestors. In the case of multiple inherited operations with the same identity, the operation used is that from the first ancestor which contains it (in the ancestor `let'). An operation may be applied to any Scheme data object--not just instances. As code which creates instances is just code, there are no "classes" and no meta-ANYTHING. Method dispatch is by a procedure call a la CLOS rather than by `send' syntax a la Smalltalk. _Disclaimer:_ There are a number of optimizations which can be made. This implementation is expository (although performance should be quite reasonable). See the L&FP paper for some suggestions. automatically generated by info2www version 1.2.2.9 |
