func NewEventHandler(s *State) *EventHandler

NewEventHandler creates a new EventHandler.

func (*EventHandler) AddGlobalMiddleware 

func (h *EventHandler) AddGlobalMiddleware(f interface{}) error

AddGlobalMiddleware adds the passed middleware as a global middleware.

The scheme of a middleware func is func(*State, e) where e is either a pointer to an event, *Base or interface{}. Optionally, a middleware may return an error.

func (*EventHandler) AddHandler 

func (h *EventHandler) AddHandler(f interface{}, middlewares ...interface{}) (func(), error)

AddHandler adds a handlers with the passed globalMiddlewares to the event handlers.

Middlewares must be of the same type as the handlers or must be an interface{} or Base handlers.
