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?

should work, but don't forget to derive 'derived' from base: class derived : base {...} On Wed, Mar 25, 2009 at 10:13 AM, Alex MDC wrote:

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?
