Types

type Closure

type Closure struct {
	Id  uintptr
	Fnc interface{}
}

func NewClosure

func NewClosure(f interface{}) *Closure

type Event

type Event struct {
	// contains filtered or unexported fields
}

Example

// create event object (usually exposed through a public struct that holds all the different event types)
event := NewEvent(intStringCaller)

// we have to wrap a function in a closure to make it identifiable
closure1 := NewClosure(func(param1 int, param2 string) {
	fmt.Println("#1 " + param2 + ": " + strconv.Itoa(param1))
})

// multiple subscribers can attach to an event (closures can be inlined)
event.Attach(closure1)
event.Attach(NewClosure(func(param1 int, param2 string) {
	fmt.Println("#2 " + param2 + ": " + strconv.Itoa(param1))
}))

// trigger the event
event.Trigger(1, "Hello World")

// unsubscribe the first closure and trigger again
event.Detach(closure1)
event.Trigger(1, "Hello World")

Output:

#1 Hello World: 1
#2 Hello World: 1
#2 Hello World: 1
