template<typename A> unspecified operator=(A & a);
Lazy assignment expression
Returns: |
A new expression node representing the assignment operation. |
template<typename A> unspecified operator=(A const & a);
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
template<typename A> unspecified operator=(A & a) const;
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
template<typename A> unspecified operator=(A const & a) const;
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
template<typename A> unspecified operator[](A & a);
Lazy subscript expression
Returns: |
A new expression node representing the subscript operation. |
template<typename A> unspecified operator[](A const & a);
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
template<typename A> unspecified operator[](A & a) const;
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
template<typename A> unspecified operator[](A const & a) const;
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
template<typename... A> unspecified operator()(A const &... a);
Lazy function call
Returns: |
A new expression node representing the function call operation. |
template<typename... A> unspecified operator()(A const &... a) const;
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
