The parameter types of the +// functions are used to control the parsing of the input. +// +// Implementation description +// ========================== +// +// When a function is registered, an 'invoker' template is instantiated with +// the function's type. The 'invoker' fetches a value from the 'arg_source' +// for each parameter of the function into a tuple and finally invokes the the +// function with these values as arguments. The invoker's entrypoint, which +// is a function of the callable builtin that describes the function to call and +// a reference to the 'arg_source', is partially bound to the registered +// function and put into a map so it can be found by name during parsing. + +#include <map> +#include <string> +#include <stdexcept> + +#include <boost/bind.hpp> +#include <boost/function.hpp> +#include <boost/range.hpp> + +#include <boost/lambda/lambda.hpp> + +#include <iostream> + +using boost::lambda::constant; +using boost::lambda::constant_ref; +using boost::lambda::var; + +/***************************************************************************** +* Output control +*****************************************************************************/ +#ifdef DEBUG_ON +using std::cout; +#else +static std::ostringstream cout; +#endif + +/***************************************************************************** +* Example data, functions, classes +*****************************************************************************/ +// sensing globals +static std::string gs; +static float gf; +static int gi; +static LLSD gl; + +void clear() +{ + gs.clear(); + gf = 0; + gi = 0; + gl = LLSD(); +} + +void abc(const std::string& message) +{ + cout << "abc('" << message << "')\n"; + gs = message; +} + +void def(float value, std::string desc) +{ + cout << "def(" << value << ", '" << desc << "')\n"; + gf = value; + gs = desc; +} + +void ghi(const std::string& foo, int bar) +{ + cout << "ghi('" << foo << "', " << bar << ")\n"; + gs = foo; + gi = bar; +} + +void jkl(const char* message) +{ + cout << "jkl('" << message << "')\n"; + gs = message; +} + +void somefunc(const LLSD& value) +{ + cout << "somefunc(" << value << ")\n"; + gl = value; +} + +class Dummy +{ +public: + Dummy(): _id("Dummy") {} + + void mno(const std::string& message) + { + cout << _id << "::mno('" << message << "')\n"; + s = message; + } + + void pqr(float value, std::string desc) + { + cout << _id << "::pqr(" << value << ", '" << desc << "')\n"; + f = value; + s = desc; + } + + void stu(const std::string& foo, int bar) + { + cout << _id << "::stu('" << foo << "', " << bar << ")\n"; + s = foo; + i = bar; + } + + void vwx(const char* message) + { + cout << _id << "::vwx('" << message << "')\n"; + s = message; + } + + static void yz1(const std::string& message) + { + cout << "Dummy::yz1('" << message << "')\n"; + // can't access sensing members... + gs = message; + } + + // sensing members + std::string s; + float f; + int i; + +private: + std::string _id; +}; + +/***************************************************************************** +* TUT +*****************************************************************************/ +namespace tut +{ + struct lleventdispatcher_data + { + WrapLL_ERRS redirect; + LLEventDispatcher work; + Dummy dummy; + + lleventdispatcher_data(): + work("test dispatcher", "op") + { + // This object is reconstructed for every test<n> method.
