Consider the following: class DirectoryIterator; namespace detail { class FileDataProxy; class DirectoryIteratorImpl { friend class DirectoryIterator; friend class FileDataProxy; WIN32_FIND_DATAW currentData; HANDLE hFind; std::wstring root; DirectoryIteratorImpl(); ...
I have written a class with protected constructor, so that new instances can only be produced with a static create() function which returns shared_ptr's to my class. To provide efficient allocation I'd like to use boost::make_shared inside the create function, however the compiler complains that my class constructor is protected inside b...
Given an abstract interface and an implementation derived from that interface, where constructors are protected (creation of these objects only being available from a class factory - to implement a DI pattern), how can I make use of make_shared in the factory function? For example: class IInterface { public: virtual void Me...
