// All public classes in //ios/web_view must be prefixed with CWV_EXPORT, so
// that clients of //ios/web_view dynamic library can link them.
//
// This is because a dynamic library only exports symbols marked
// __attribute__((visibility("default"))).
//
// Define a macro CWV_EXPORT instead of directly using __attribute__.
// This makes it possible to export symbols only when *building* the dynamic
// library (by checking CWV_IMPLEMENTATION), not when *using* the dynamic
// library.
