Detailed Description
template<typename L, typename R, typename... A>
class Pt::Lambda< L, R, A >
The callable is stored by value and must therefore be copyable. For a non-generic lambda, the factory derives the Callable interface from operator(). Generic lambdas require an explicitly supplied signature.
Member Function Documentation
◆ operator()()
|
virtual |
Since this class template is partially specialized, the passed arguments ARGUMENTS must match the template parameters.
Implements Callable< R, A... >.
◆ 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.
◆ invoke()
|
virtualinherited |
Inherited from Invokable. Ignores the return value of the Callable. Since this class template is partially specialized, the passed arguments ARGUMENTS must match the template parameters.
Implements Invokable< A... >.
