# go-delegate
A multicast delegate implementation of Go, similar to [delegate in C#](https://learn.microsoft.com/en-us/dotnet/csharp/programming-guide/delegates/)
## Example
no generics & variadic function
```
func f1(args ...interface{}) {
println("f1")
}
func f2(args ...interface{}) {
println("f2")
}
func main() {
d := Delegate{}
d = d.Combine(f1)
d = d.Combine(f2)
d.Invoke()
}
```
generics & parameters
```
func f() {
println("f")
}
func f1(a int) {
println("f1", a)
}
func f2(a, b int) {
println("f2", a, b)
}
func main() {
d := Action{}
d = d.Combine(f)
d.Invoke()
d1 := Action1[int]{}
d1 = d.Combine(f1)
d1.Invoke(1)
d2 := Action2[int, int]{}
d2 = d.Combine(f2)
d2.Invoke(1, 2)
}
```
There is Action, Action1, ... Action7, that binds no parameters and up to 7 parameters.
