deanm@google.com96aac0a2008-08-25 22:42:07 +0900[diff] [blame]5// A Tuple is a generic templatized container, similar in concept to std::pair.
ojan@google.com38355092008-10-10 06:58:05 +0900[diff] [blame]6// There are classes Tuple0 to Tuple6, cooresponding to the number of elements
7// it contains. The convenient MakeTuple() function takes 0 to 6 arguments,
deanm@google.com96aac0a2008-08-25 22:42:07 +0900[diff] [blame]8// and will construct and return the appropriate Tuple object. The functions
9// DispatchToMethod and DispatchToFunction take a function pointer or instance
10// and method pointer, and unpack a tuple into arguments to the call.
11//
12// Tuple elements are copied by value, and stored in the tuple. See the unit
13// tests for more details of how/when the values are copied.
14//
15// Example usage:
16// // These two methods of creating a Tuple are identical.
17// Tuple2<int, const char*> tuple_a(1, "wee");
18// Tuple2<int, const char*> tuple_b = MakeTuple(1, "wee");
19//
20// void SomeFunc(int a, const char* b) { }
21// DispatchToFunction(&SomeFunc, tuple_a); // SomeFunc(1, "wee")
22// DispatchToFunction(
23// &SomeFunc, MakeTuple(10, "foo")); // SomeFunc(10, "foo")
24//
25// struct { void SomeMeth(int a, int b, int c) { } } foo;
26// DispatchToMethod(&foo, &Foo::SomeMeth, MakeTuple(1, 2, 3));
27// // foo->SomeMeth(1, 2, 3);

67// RunnableMethod and IPC::MessageWithTuple.
