Hi Everyone, Uploaded to the vault [0] is the implementation of the dispatcher library. If there is enough interest, I would like to propose this library for inclusion into the Boost C++ Library. The documentation is yet unfinished, though I am not very sure about the contents of the documentation. However, I have put enough documentation with regards to how the library is designed, and used. A synopsis on how it can be used can be summed up in the following example code: [start code] #include <boost/dispatch.hpp> using boost::dispatch; //... dispatcher<int()> d; d[0] = int_function_1; d[1] = int_function_2; d[0]() // calls `int_function_1' d[1]() // calls `inf_function_2' d.unset(1); try { d[1]() // throws an unregistered_handler exception } catch (unregistered_handler & e) { // .. do nothing }; dispatcher<int()>::invoke_ d; d[1] = int_function_2; d << 0 << 1 ; // calls d[0] and d[1] in specified order. [end code] It also supports multiple argument callback registration (ala Signals): [start code] dispatcher<int (double, int, std::string)> d; d[0] = function_returns_int_and_takes_double_int_and_string; [end code] It also allows for parameterized index type definition: [start code] dispatcher<int(int), std::string> d; d["zero"] = function_returns_int_and_takes_int; [end code] The included documentation (doc/html) contains more information on the uses of the library, while the unit test (test/dispatch_test.cpp) can be referred to regarding the actual details on the usage. The project is currently hosted in sourceforge [1] and has been tested/built against RC_1_34_0 using MSVC 8.0 -- this is configured to be built only with BBv2. Have a great day everyone! Your comments and insights will be most appreciated.
