| // Google Test defines the testing::Message class to allow construction of |
| // test messages via the << operator. The idea is that anything |
| // streamable to std::ostream can be streamed to a testing::Message. |
| // This allows a user to use his own types in Google Test assertions by |
| // overloading the << operator. |
| // |
| // util/gtl/stl_logging-inl.h overloads << for STL containers. These |
| // overloads cannot be defined in the std namespace, as that will be |
| // undefined behavior. Therefore, they are defined in the global |
| // namespace instead. |
| // |
| // C++'s symbol lookup rule (i.e. Koenig lookup) says that these |
| // overloads are visible in either the std namespace or the global |
| // namespace, but not other namespaces, including the testing |
| // namespace which Google Test's Message class is in. |
| // |
| // To allow STL containers (and other types that has a << operator |
| // defined in the global namespace) to be used in Google Test assertions, |
| // testing::Message must access the custom << operator from the global |
| // namespace. Hence this helper function. |
| // |
| // Note: Jeffrey Yasskin suggested an alternative fix by "using |
| // ::operator<<;" in the definition of Message's operator<<. That fix |
| // doesn't require a helper function, but unfortunately doesn't |
| // compile with MSVC. |
