Re: [Boost-users] [corrected]How to delay the initialisation of a member in a C++ base class until the ctor of derived class is executed?

Is there any C++ design pattern could achieve it? Thanks

Since you're passing the size into the derived constructor, why don't you just pass it through to the base constructor? class base { public: base(size_t array_size):size(array_size) { p_array.reset(new unsigned char[size]); } private: size_t size; boost::shared_array<unsigned char> p_array; }; class derived { public: derived(size_t array_size):base(array_size) { } }; Will that work for you?
