C++ Scripting System Using Expression Predicates EmilDotchevski@hotmail.com COMPILER COMPATIBILITY To best of my knowledge, this source code is ANSI C++ compliant. It has been explicitly tested with the following compilers: Microsoft C++ Compiler, version 12 and 13 (MSVC 6 and 7) Intel C++ Compiler, version 7.0 g++, version 3.2 Comeau Computing C++ Compiler, version 4.3.0.1 ADDITIONS TO THE ARTICLE MATERIAL This example source code is more advanced than the code snippets given in the article. Most notably, select_root and select_child templates are extended to produce valid results when used with types containing the const modifier. SUGGESTED IMPROVEMENTS The predicate system is independent of the container class used to store pointers. As mentioned in the article, using std::set is not ideal. I would recommend using a custom-designed container based on std::vector, with efficient usage of reserve(). It is a good idea to not store pointers in the sets used to process objects. For example, it is possible to use the so-called weak pointers. The C++ Boost library provides an excellent implementation of weak pointers (http://www.boost.org).
