Added new methods extension/1 and extensions/1 to + the library object "proto_hierarchy.lgt". + + Documented the concept of "parametric object proxy".

Proxies represent different instantiations of a parametric +object parameters. They may be stored on the database as Prolog facts. This +results in a very compact representation, which can be an advantage when +dealing with a large number of objects. However, this is also a fragile +solution as changes on the parametric object ancestors may imply changes to +the number and meaning of the parametric object parameters which, in turn, +may imply changes to all the Prolog facts used to represent the individual +objects. diff --git a/Logtalk/examples/proxies/SCRIPT b/Logtalk/examples/proxies/SCRIPT new file mode 100644 index 000000000..a8889de6a --- /dev/null +++ b/Logtalk/examples/proxies/SCRIPT @@ -0,0 +1,24 @@ +================================================================= +Logtalk - Object oriented extension to Prolog +Release 2.27.1 + +Copyright (c) 1998-2006 Paulo Moura.

These methods (with the possible exception of parameter/2) are translated to a single unification performed at compile time with a clause head context argument. Therefore, they can be freely used without worrying about performance penalties. When called from inside a category, these methods refer to the execution context of the object importing the category.

For instance, the error terms that are generated by some Logtalk built-in predicates assume that the Prolog built-ins behave as defined in the ISO standard regarding error conditions. In particular, if your Prolog compiler does not support a read_term/3 built-in predicate compliant with the ISO Prolog Standard definition, then the current version of the Logtalk preprocessor will not be able to detect misspell variables in your source code.

    Coding style guidlines

    + +

    +It is suggested that all code between an entity opening and closing directives be indented by one tab stop. When defining entity code, both directives and predicates, Prolog coding style guidelines may be applied. All Logtalk source files, examples, and standard library entities use four-space tabs for laying out code. Closed related entities should be defined in the same source file. Entities that might be useful in different contexts (such as library entities) are best defined in their own source files. +
