| // A Tuple is a generic templatized container, similar in concept to std::pair. |
| // There are classes Tuple0 to Tuple6, cooresponding to the number of elements |
| // it contains. The convenient MakeTuple() function takes 0 to 6 arguments, |
| // and will construct and return the appropriate Tuple object. The functions |
| // DispatchToMethod and DispatchToFunction take a function pointer or instance |
| // and method pointer, and unpack a tuple into arguments to the call. |
| // |
| // Tuple elements are copied by value, and stored in the tuple. See the unit |
| // tests for more details of how/when the values are copied. |
| // |
| // Example usage: |
| // // These two methods of creating a Tuple are identical. |
| // Tuple2<int, const char*> tuple_a(1, "wee"); |
| // Tuple2<int, const char*> tuple_b = MakeTuple(1, "wee"); |
| // |
| // void SomeFunc(int a, const char* b) { } |
| // DispatchToFunction(&SomeFunc, tuple_a); // SomeFunc(1, "wee") |
| // DispatchToFunction( |
| // &SomeFunc, MakeTuple(10, "foo")); // SomeFunc(10, "foo") |
| // |
| // struct { void SomeMeth(int a, int b, int c) { } } foo; |
| // DispatchToMethod(&foo, &Foo::SomeMeth, MakeTuple(1, 2, 3)); |
| // // foo->SomeMeth(1, 2, 3); |
