std::basic_ostream <U, V>& operator<<( std::basic_ostream <U, V>& os, const std::shared_ptr <T>& ptr );
 
 
std::basic_ostream <U, V>& operator<<( std::basic_ostream <U, V>& os, const std::shared_ptr <T>& ptr );
Inserts the value of the pointer stored in ptr into the output stream os.
Equivalent to os << ptr.get().
