             Summary: Allow examples to use C++11 override
                 Key: PROTON-1163
                 URL: https://issues.apache.org/jira/browse/PROTON-1163
             Project: Qpid Proton
          Issue Type: Improvement
          Components: cpp-binding
            Reporter: Andrew Stitcher
            Assignee: Cliff Jansen


The C++11 override feature is extremely useful for detecting when you have the wrong signature for an overridden member function sued for an interface.

As we are developing the C++ API which uses inheritance from proton::handler in exactly this way it is extremely helpful to get the compiler to find mistakes in this regard especially as the interface changes.

So this change introduces override in the appropriate useful places in a way that is backward compatible with C++03 and earlier with some small limitiations (essentially you can't use the keyword "override" in your code).
