virtual std::unique_ptr<std::istream> IFileAccess::open ( const std::string & url )

pure virtual

Find the URL and returns a unique_ptr to an input stream interface of an object that can be used to read from the file the URL is pointing to.

Returns an empty pointer if the URL cannot be resolved.

virtual const std::vector<std::string>& IFileAccess::protocols ( ) const

pure virtual

Protocols supported by the instance.
