Use the ``CM_AUTO_PTR`` macro instead. +* Use ``CM_EQ_DELETE;`` instead of ``= delete;``. + + Defining functions as *deleted* is not supported in C++98. Using + ``CM_EQ_DELETE`` will delete the functions if the compiler supports it and + give them no implementation otherwise. Calling such a function will lead + to compiler errors if the compiler supports *deleted* functions and linker + errors otherwise. + +* Use ``CM_DISABLE_COPY(Class)`` to mark classes as non-copyable. + + The ``CM_DISABLE_COPY`` macro should be used in the private section of a + class to make sure that attempts to copy or assign an instance of the class + lead to compiler errors even if the compiler does not support *deleted* + functions. As a guideline, all polymorphic classes should be made + non-copyable in order to avoid slicing. Classes that are composed of or + derived from non-copyable classes must also be made non-copyable explicitly + with ``CM_DISABLE_COPY``. + * Use ``size_t`` instead of ``std::size_t``. Various implementations have differing implementation of ``size_t``. |
