carb::events::IEventListener

class IEventListener : public carb::IObject 

Interface to implement for event listener.

Subclassed by carb::events::LambdaEventListener

Public Functions

virtual void onEvent(IEvent *e) = 0

Function to be implemented that will handle an event.

Parameters: e – The event to process. To stop further propagation of the event, call IEvent::consume().

virtual size_t addRef() = 0

Atomically add 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.

virtual size_t release() = 0

Atomically subtracts one from the reference count.

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.

Public Static Functions

static inline constexpr carb::InterfaceDesc getInterfaceDesc() noexcept

Returns information about this interface.

Auto-generated by CARB_PLUGIN_INTERFACE() or CARB_PLUGIN_INTERFACE_EX.

Returns: The carb::InterfaceDesc struct with information about this interface.

static inline constexpr carb::InterfaceDesc getLatestInterfaceDesc() noexcept

Returns information about the latest version of this interface.

Auto-generated by CARB_PLUGIN_INTERFACE() or CARB_PLUGIN_INTERFACE_EX.

Returns: The carb::InterfaceDesc struct with information about the latest version of this interface.
