you don't use this include in this header file.

virtual d'tor, DISALLOW_COPY etc.

[tfarina, 2012/12/20 01:43:34]

you don't need this subtle pattern of DISALLOW_COPY in an abstract class (aka
interface). Just let the subclass do this. But yeah, a protected virtual
destructor is missing though.

Done.
