Detailed Description
template<typename R, typename ClassT, typename... As>
class Pt::Method< R, ClassT, As >
The Method class wraps member functions as Callable objects so that they can be used with the signals/slots framework.
Member Function Documentation
◆ call()
|
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.
Implements Callable< R, As... >.
◆ invoke()
|
virtual |
The passed arguments must match the template parameters.
Implements Callable< R, As... >.
◆ clone()
|
pure virtualinherited |
A copy of the instance is created with new is returned. Ownership is transfered to the caller, who has to delete it.
