}  // namespace testing

// The ACTION* family of macros can be used in a namespace scope to
// define custom actions easily.  The syntax:
//
//   ACTION(name) { statements; }
//
// will define an action with the given name that executes the
// statements.  The value returned by the statements will be used as
// the return value of the action.  Inside the statements, you can
// refer to the K-th (0-based) argument of the mock function by
// 'argK', and refer to its type by 'argK_type'.  For example:
//
//   ACTION(IncrementArg1) {
//     arg1_type temp = arg1;
//     return ++(*temp);
//   }
//
// allows you to write
//
//   ...WillOnce(IncrementArg1());
//
// You can also refer to the entire argument tuple and its type by
// 'args' and 'args_type', and refer to the mock function type and its
// return type by 'function_type' and 'return_type'.
//
// Note that you don't need to specify the types of the mock function
// arguments.  However rest assured that your code is still type-safe:
// you'll get a compiler error if *arg1 doesn't support the ++
// operator, or if the type of ++(*arg1) isn't compatible with the
// mock function's return type, for example.
//
// Sometimes you'll want to parameterize the action.   For that you can use
// another macro:
//
//   ACTION_P(name, param_name) { statements; }
//
// For example:
//
//   ACTION_P(Add, n) { return arg0 + n; }
//
// will allow you to write:
//
//   ...WillOnce(Add(5));
//
// Note that you don't need to provide the type of the parameter
// either.  If you need to reference the type of a parameter named
// 'foo', you can write 'foo_type'.  For example, in the body of
// ACTION_P(Add, n) above, you can write 'n_type' to refer to the type
// of 'n'.
//
// We also provide ACTION_P2, ACTION_P3, ..., up to ACTION_P10 to support
// multi-parameter actions.
//
// For the purpose of typing, you can view
//
//   ACTION_Pk(Foo, p1, ..., pk) { ... }
//
// as shorthand for
//
//   template <typename p1_type, ..., typename pk_type>
//   FooActionPk<p1_type, ..., pk_type> Foo(p1_type p1, ..., pk_type pk) { ... }
//
// In particular, you can provide the template type arguments
// explicitly when invoking Foo(), as in Foo<long, bool>(5, false);
// although usually you can rely on the compiler to infer the types
// for you automatically.  You can assign the result of expression
// Foo(p1, ..., pk) to a variable of type FooActionPk<p1_type, ...,
// pk_type>.  This can be useful when composing actions.
//
// You can also overload actions with different numbers of parameters:
//
//   ACTION_P(Plus, a) { ... }
//   ACTION_P2(Plus, a, b) { ... }
//
// While it's tempting to always use the ACTION* macros when defining
// a new action, you should also consider implementing ActionInterface
// or using MakePolymorphicAction() instead, especially if you need to
// use the action a lot.  While these approaches require more work,
// they give you more control on the types of the mock function
// arguments and the action parameters, which in general leads to
// better compiler error messages that pay off in the long run.  They
// also allow overloading actions based on parameter types (as opposed
// to just based on the number of parameters).
//
// CAVEAT:
//
// ACTION*() can only be used in a namespace scope.  The reason is
// that C++ doesn't yet allow function-local types to be used to
// instantiate templates.  The up-coming C++0x standard will fix this.
// Once that's done, we'll consider supporting using ACTION*() inside
// a function.
//

//
// To learn more about using these macros, please search for 'ACTION'
// on http://code.google.com/p/googlemock/wiki/CookBook.

// Sometimes you want to give an action explicit template parameters
// that cannot be inferred from its value parameters.  ACTION() and
// ACTION_P*() don't support that.  ACTION_TEMPLATE() remedies that
// and can be viewed as an extension to ACTION() and ACTION_P*().
//
// The syntax:
//
//   ACTION_TEMPLATE(ActionName,
//                   HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
//                   AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
//
// defines an action template that takes m explicit template
// parameters and n value parameters.  name_i is the name of the i-th
// template parameter, and kind_i specifies whether it's a typename,
// an integral constant, or a template.  p_i is the name of the i-th
// value parameter.
//
// Example:
//
//   // DuplicateArg<k, T>(output) converts the k-th argument of the mock
//   // function to type T and copies it to *output.
//   ACTION_TEMPLATE(DuplicateArg,
//                   HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
//                   AND_1_VALUE_PARAMS(output)) {
//     *output = T(std::tr1::get<k>(args));
//   }
//   ...
//     int n;
//     EXPECT_CALL(mock, Foo(_, _))
//         .WillOnce(DuplicateArg<1, unsigned char>(&n));
//
// To create an instance of an action template, write:
//
//   ActionName<t1, ..., t_m>(v1, ..., v_n)
//
// where the ts are the template arguments and the vs are the value
// arguments.  The value argument types are inferred by the compiler.
// If you want to explicitly specify the value argument types, you can
// provide additional template arguments:
//
//   ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
//
// where u_i is the desired type of v_i.
//
// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
// number of value parameters, but not on the number of template
// parameters.  Without the restriction, the meaning of the following
// is unclear:
//
//   OverloadedAction<int, bool>(x);
//
// Are we using a single-template-parameter action where 'bool' refers
// to the type of x, or are we using a two-template-parameter action
// where the compiler is asked to infer the type of x?
//
// Implementation notes:
//
// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
// implementing ACTION_TEMPLATE.  The main trick we use is to create
// new macro invocations when expanding a macro.  For example, we have
//
//   #define ACTION_TEMPLATE(name, template_params, value_params)
//       ... GMOCK_INTERNAL_DECL_##template_params ...
//
// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
// to expand to
//
//       ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
//
// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
// preprocessor will continue to expand it to
//
//       ... typename T ...
//
// This technique conforms to the C++ standard and is portable.  It
// allows us to implement action templates using O(N) code, where N is
// the maximum number of template/value parameters supported.  Without
// using it, we'd have to devote O(N^2) amount of code to implement all
// combinations of m and n.

// Various overloads for InvokeArgument<N>().
//
// The InvokeArgument<N>(a1, a2, ..., a_k) action invokes the N-th
// (0-based) argument, which must be a k-ary callable, of the mock
// function, with arguments a1, a2, ..., a_k.
//
// Notes:
//
//   1. The arguments are passed by value by default.  If you need to
//   pass an argument by reference, wrap it inside ByRef().  For
//   example,
//
//     InvokeArgument<1>(5, string("Hello"), ByRef(foo))
//
//   passes 5 and string("Hello") by value, and passes foo by
//   reference.
//
//   2. If the callable takes an argument by reference but ByRef() is
//   not used, it will receive the reference to a copy of the value,
//   instead of the original value.  For example, when the 0-th
//   argument of the mock function takes a const string&, the action
//
//     InvokeArgument<0>(string("Hello"))
//
//   makes a copy of the temporary string("Hello") object and passes a
//   reference of the copy, instead of the original temporary object,
//   to the callable.  This makes it easy for a user to define an
//   InvokeArgument action from temporary values and have it performed
//   later.

// A MockFunction<F> class has one mock method whose type is F.  It is
// useful when you just want your test code to emit some messages and
// have Google Mock verify the right messages are sent (and perhaps at
// the right times).  For example, if you are exercising code:
//
//   Foo(1);
//   Foo(2);
//   Foo(3);
//
// and want to verify that Foo(1) and Foo(3) both invoke
// mock.Bar("a"), but Foo(2) doesn't invoke anything, you can write:
//
// TEST(FooTest, InvokesBarCorrectly) {
//   MyMock mock;
//   MockFunction<void(string check_point_name)> check;
//   {
//     InSequence s;
//
//     EXPECT_CALL(mock, Bar("a"));
//     EXPECT_CALL(check, Call("1"));
//     EXPECT_CALL(check, Call("2"));
//     EXPECT_CALL(mock, Bar("a"));
//   }
//   Foo(1);
//   check.Call("1");
//   Foo(2);
//   check.Call("2");
//   Foo(3);
// }
//
// The expectation spec says that the first Bar("a") must happen
// before check point "1", the second Bar("a") must happen after check
// point "2", and nothing should happen between the two check
// points. The explicit check points make it easy to tell which
// Bar("a") is called by which call to Foo().

}  // namespace testing


// The MATCHER* family of macros can be used in a namespace scope to
// define custom matchers easily.
//
// Basic Usage
// ===========
//
// The syntax
//
//   MATCHER(name, description_string) { statements; }
//
// defines a matcher with the given name that executes the statements,
// which must return a bool to indicate if the match succeeds.  Inside
// the statements, you can refer to the value being matched by 'arg',
// and refer to its type by 'arg_type'.
//
// The description string documents what the matcher does, and is used
// to generate the failure message when the match fails.  Since a
// MATCHER() is usually defined in a header file shared by multiple
// C++ source files, we require the description to be a C-string
// literal to avoid possible side effects.  It can be empty, in which
// case we'll use the sequence of words in the matcher name as the
// description.
//
// For example:
//
//   MATCHER(IsEven, "") { return (arg % 2) == 0; }
//
// allows you to write
//
//   // Expects mock_foo.Bar(n) to be called where n is even.
//   EXPECT_CALL(mock_foo, Bar(IsEven()));
//
// or,
//
//   // Verifies that the value of some_expression is even.
//   EXPECT_THAT(some_expression, IsEven());
//
// If the above assertion fails, it will print something like:
//
//   Value of: some_expression
//   Expected: is even
//     Actual: 7
//
// where the description "is even" is automatically calculated from the
// matcher name IsEven.
//
// Argument Type
// =============
//
// Note that the type of the value being matched (arg_type) is
// determined by the context in which you use the matcher and is
// supplied to you by the compiler, so you don't need to worry about
// declaring it (nor can you).  This allows the matcher to be
// polymorphic.  For example, IsEven() can be used to match any type
// where the value of "(arg % 2) == 0" can be implicitly converted to
// a bool.  In the "Bar(IsEven())" example above, if method Bar()
// takes an int, 'arg_type' will be int; if it takes an unsigned long,
// 'arg_type' will be unsigned long; and so on.
//
// Parameterizing Matchers
// =======================
//
// Sometimes you'll want to parameterize the matcher.  For that you
// can use another macro:
//
//   MATCHER_P(name, param_name, description_string) { statements; }
//
// For example:
//
//   MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
//
// will allow you to write:
//
//   EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
//
// which may lead to this message (assuming n is 10):
//
//   Value of: Blah("a")
//   Expected: has absolute value 10
//     Actual: -9
//
// Note that both the matcher description and its parameter are
// printed, making the message human-friendly.
//
// In the matcher definition body, you can write 'foo_type' to
// reference the type of a parameter named 'foo'.  For example, in the
// body of MATCHER_P(HasAbsoluteValue, value) above, you can write
// 'value_type' to refer to the type of 'value'.
//
// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P10 to
// support multi-parameter matchers.
//
// Describing Parameterized Matchers
// =================================
//
// The last argument to MATCHER*() is a string-typed expression.  The
// expression can reference all of the matcher's parameters and a
// special bool-typed variable named 'negation'.  When 'negation' is
// false, the expression should evaluate to the matcher's description;
// otherwise it should evaluate to the description of the negation of
// the matcher.  For example,
//
//   using testing::PrintToString;
//
//   MATCHER_P2(InClosedRange, low, hi,
//       string(negation ? "is not" : "is") + " in range [" +
//       PrintToString(low) + ", " + PrintToString(hi) + "]") {
//     return low <= arg && arg <= hi;
//   }
//   ...
//   EXPECT_THAT(3, InClosedRange(4, 6));
//   EXPECT_THAT(3, Not(InClosedRange(2, 4)));
//
// would generate two failures that contain the text:
//
//   Expected: is in range [4, 6]
//   ...
//   Expected: is not in range [2, 4]
//
// If you specify "" as the description, the failure message will
// contain the sequence of words in the matcher name followed by the
// parameter values printed as a tuple.  For example,
//
//   MATCHER_P2(InClosedRange, low, hi, "") { ... }
//   ...
//   EXPECT_THAT(3, InClosedRange(4, 6));
//   EXPECT_THAT(3, Not(InClosedRange(2, 4)));
//
// would generate two failures that contain the text:
//
//   Expected: in closed range (4, 6)
//   ...
//   Expected: not (in closed range (2, 4))
//
// Types of Matcher Parameters
// ===========================
//
// For the purpose of typing, you can view
//
//   MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
//
// as shorthand for
//
//   template <typename p1_type, ..., typename pk_type>
//   FooMatcherPk<p1_type, ..., pk_type>
//   Foo(p1_type p1, ..., pk_type pk) { ... }
//
// When you write Foo(v1, ..., vk), the compiler infers the types of
// the parameters v1, ..., and vk for you.  If you are not happy with
// the result of the type inference, you can specify the types by
// explicitly instantiating the template, as in Foo<long, bool>(5,
// false).  As said earlier, you don't get to (or need to) specify
// 'arg_type' as that's determined by the context in which the matcher
// is used.  You can assign the result of expression Foo(p1, ..., pk)
// to a variable of type FooMatcherPk<p1_type, ..., pk_type>.  This
// can be useful when composing matchers.
//
// While you can instantiate a matcher template with reference types,
// passing the parameters by pointer usually makes your code more
// readable.  If, however, you still want to pass a parameter by
// reference, be aware that in the failure message generated by the
// matcher you will see the value of the referenced object but not its
// address.
//
// Explaining Match Results
// ========================
//
// Sometimes the matcher description alone isn't enough to explain why
// the match has failed or succeeded.  For example, when expecting a
// long string, it can be very helpful to also print the diff between
// the expected string and the actual one.  To achieve that, you can
// optionally stream additional information to a special variable
// named result_listener, whose type is a pointer to class
// MatchResultListener:
//
//   MATCHER_P(EqualsLongString, str, "") {
//     if (arg == str) return true;
//
//     *result_listener << "the difference: "
///                     << DiffStrings(str, arg);
//     return false;
//   }
//
// Overloading Matchers
// ====================
//
// You can overload matchers with different numbers of parameters:
//
//   MATCHER_P(Blah, a, description_string1) { ... }
//   MATCHER_P2(Blah, a, b, description_string2) { ... }
//
// Caveats
// =======
//
// When defining a new matcher, you should also consider implementing
// MatcherInterface or using MakePolymorphicMatcher().  These
// approaches require more work than the MATCHER* macros, but also
// give you more control on the types of the value being matched and
// the matcher parameters, which may leads to better compiler error
// messages when the matcher is used wrong.  They also allow
// overloading matchers based on parameter types (as opposed to just
// based on the number of parameters).
//
// MATCHER*() can only be used in a namespace scope.  The reason is
// that C++ doesn't yet allow function-local types to be used to
// instantiate templates.  The up-coming C++0x standard will fix this.
// Once that's done, we'll consider supporting using MATCHER*() inside
// a function.
//

// Implements class templates NiceMock and StrictMock.
//
// Given a mock class MockFoo that is created using Google Mock,
// NiceMock<MockFoo> is a subclass of MockFoo that allows
// uninteresting calls (i.e. calls to mock methods that have no
// EXPECT_CALL specs), and StrictMock<MockFoo> is a subclass of
// MockFoo that treats all uninteresting calls as errors.
//
// NiceMock and StrictMock "inherits" the constructors of their
// respective base class, with up-to 10 arguments.  Therefore you can
// write NiceMock<MockFoo>(5, "a") to construct a nice mock where
// MockFoo has a constructor that accepts (int, const char*), for
// example.
//
// A known limitation is that NiceMock<MockFoo> and
// StrictMock<MockFoo> only works for mock methods defined using the
// MOCK_METHOD* family of macros DIRECTLY in the MockFoo class.  If a
// mock method is defined in a base class of MockFoo, the "nice" or
// "strict" modifier may not affect it, depending on the compiler.  In
// particular, nesting NiceMock and StrictMock is NOT supported.
//
// Another known limitation is that the constructors of the base mock
// cannot have arguments passed by non-const reference, which are
// banned by the Google C++ style guide anyway.
