Wraps free functions into a generic callable for use with the signals/slots. More...
Inherits Callable< R, As... >.
Public Types | |
| typedef R(*) | FuncT(As...) |
| The function signature wrapped by this class. | |
Public Member Functions | |
| Function (FuncT function) | |
| Construct from function pointer. | |
| R | call (As... args) const |
| Calls the callable entity and returns its result. | |
| void | invoke (As... args) const |
| Invokes the invokable entity with the given arguments. | |
| Function * | clone () const |
| Returns a copy of this instance. | |
| bool | operator== (const Function &other) const |
| Returns true if both use the same function pointer. | |
| R | operator() (As... args) const |
| Same as call(). | |

(Note that these are not member symbols.) | |
| ConstMethod< R, ClassT, As... > | callable (ClassT &object, R(BaseT::*method)(As...) const) |
| Returns a ConstMethod object for the given object/method pair. | |
| Function< R, As... > | callable (R(*function)(As...)) |
| Returns a Function wrapper for the given free/static function. | |
| Method< R, ClassT, As... > | callable (ClassT &object, R(BaseT::*method)(As...)) |
| Returns a Method object for the given object/method pair. | |
The Function class wraps free functions in the form of a Callable, for use with the signals/slots framework.

virtual |
This is the primary non-virtual entry point used by Delegate and other callers that need the return value. All derived classes must implement this.

The passed arguments must match the template parameters.
Implements Callable< R, As... >.
|
virtual |
A copy of the instance is created with new is returned. Ownership is transfered to the caller, who has to delete it.
