// The contents of this file are identical to base/tuple.h
// 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);

// Traits ----------------------------------------------------------------------
//
// A simple traits class for tuple arguments.
//
// ValueType: the bare, nonref version of a type (same as the type for nonrefs).
// RefType: the ref version of a type (same as the type for refs).
// ParamType: what type to pass to functions (refs should not be constified).

// Tuple -----------------------------------------------------------------------
//
// This set of classes is useful for bundling 0 or more heterogeneous data types
// into a single variable. The advantage of this is that it greatly simplifies
// function objects that need to take an arbitrary number of parameters; see
// RunnableMethod and IPC::MessageWithTuple.
//
// Tuple0 is supplied to act as a 'void' type. It can be used, for example,
// when dispatching to a function that accepts no arguments (see the
// Dispatchers below).
// Tuple1<A> is rarely useful. One such use is when A is non-const ref that you
// want filled by the dispatchee, and the tuple is merely a container for that
// output (a "tier"). See MakeRefTuple and its usages.
