// Use implicit_cast as a safe version of static_cast or const_cast
// for upcasting in the type hierarchy (i.e. casting a pointer to Foo
// to a pointer to SuperclassOfFoo or casting a pointer to Foo to
// a const pointer to Foo).
// When you use implicit_cast, the compiler checks that the cast is safe.
// Such explicit implicit_casts are necessary in surprisingly many
// situations where C++ demands an exact type match instead of an
// argument type convertable to a target type.
//
// The From type can be inferred, so the preferred syntax for using
// implicit_cast is the same as for static_cast etc.:
//
// implicit_cast<ToType>(expr)
//
// implicit_cast would have been part of the C++ standard library,
// but the proposal was submitted too late. It will probably make
// its way into the language in the future.

// When you upcast (that is, cast a pointer from type Foo to type
// SuperclassOfFoo), it's fine to use implicit_cast<>, since upcasts
// always succeed. When you downcast (that is, cast a pointer from
// type Foo to type SubclassOfFoo), static_cast<> isn't safe, because
// how do you know the pointer is really of type SubclassOfFoo? It
// could be a bare Foo, or of type DifferentSubclassOfFoo. Thus,
// when you downcast, you should use this macro. In debug mode, we
// use dynamic_cast<> to double-check the downcast is legal (we die
// if it's not). In normal mode, we do the efficient static_cast<>
// instead. Thus, it's important to test in debug mode to make sure
// the cast is legal!
// This is the only place in the code we should use dynamic_cast<>.
// In particular, you SHOULDN'T be using dynamic_cast<> in order to
// do RTTI (eg code like this:
// if (dynamic_cast<Subclass1>(foo)) HandleASubclass1Object(foo);
// if (dynamic_cast<Subclass2>(foo)) HandleASubclass2Object(foo);
// You should design the code some other way not to need this.

// for compile-time type checking, and has no overhead in an
// optimized build at run-time, as it will be optimized away
// completely.

// The GMOCK_COMPILE_ASSERT macro can be used to verify that a compile time

// size of a static array:
//
// GMOCK_COMPILE_ASSERT(ARRAYSIZE(content_type_names) == CONTENT_NUM_TYPES,
// content_type_names_incorrect_size);
//
// or to make sure a struct is smaller than a certain size:
//
// GMOCK_COMPILE_ASSERT(sizeof(foo) < 128, foo_too_large);

// the expression is false, most compilers will issue a warning/error

// Implementation details of GMOCK_COMPILE_ASSERT:
//
// - GMOCK_COMPILE_ASSERT works by defining an array type that has -1
// elements (and thus is invalid) when the expression is false.
//
// - The simpler definition
//
// #define GMOCK_COMPILE_ASSERT(expr, msg) typedef char msg[(expr) ? 1 : -1]
//
// does not work, as gcc supports variable-length arrays whose sizes
// are determined at run-time (this is gcc's extension and not part
// of the C++ standard). As a result, gcc fails to reject the
// following code with the simple definition:
//
// int foo;
// GMOCK_COMPILE_ASSERT(foo, msg); // not supposed to compile as foo is
// // not a compile-time constant.
//
// - By using the type CompileAssert<(bool(expr))>, we ensures that
// expr is a compile-time constant. (Template arguments must be
// determined at compile-time.)
//
// - The outter parentheses in CompileAssert<(bool(expr))> are necessary
// to work around a bug in gcc 3.4.4 and 4.0.1. If we had written
//
// CompileAssert<bool(expr)>
//
// instead, these compilers will refuse to compile
//
// GMOCK_COMPILE_ASSERT(5 > 0, some_message);
//
// (They seem to think the ">" in "5 > 0" marks the end of the
// template argument list.)
//
// - The array size is (bool(expr) ? 1 : -1), instead of simply
//
// ((expr) ? 1 : -1).
//
// This is to avoid running into a bug in MS VC 7.1, which
// causes ((0.0) ? 1 : -1) to incorrectly evaluate to 1.
