Defined in carb/events/EventsUtils.h

class LambdaEventListener : public carb::events::IEventListener

A helper to use a std::function as an carb::events::IEventListener.

Public Functions

inline LambdaEventListener(std::function<void(IEvent*)> fn)

Constructor.

Parameters

fn – The std::function to call when onEvent() is called.

inline virtual void onEvent(IEvent *e) override

Passes the event to the std::function given to the constructor.

Parameters

e – The carb::events::IEvent to process.

inline virtual size_t addRef() override

Atomically adds one to the reference count.

Returns

The current reference count after one was added, though this value may change before read if other threads are also modifying the reference count. The return value is guaranteed to be non-zero.

inline virtual size_t release() override

If the result is zero, carb::deleteHandler() is called for this.

Returns

The current reference count after one was subtracted. If zero is returned, carb::deleteHandler() was called for this.
