| // This should be used in the private: declarations for a class. |
| // |
| // Use this macro instead of DISALLOW_COPY_AND_ASSIGN if you want to pass |
| // ownership of the type through a base::Callback without heap-allocating it |
| // into a scoped_ptr. The class must define a move constructor and move |
| // assignment operator to make this work. |
| // |
| // This version of the macro adds a Pass() function and a cryptic |
| // MoveOnlyTypeForCPP03 typedef for the base::Callback implementation to use. |
| // See IsMoveOnlyType template and its usage in base/callback_internal.h |
| // for more details. |
| // TODO(crbug.com/566182): Remove this macro and use DISALLOW_COPY_AND_ASSIGN |
