GO多指针

Question

I'm trying to create a function that receives multiple types of struct and add those pointer values to another function.

Example:

type Model1 struct {
  Name string
}

type Model2 struct {
  Type bool
}

func MyFunc(value ...interface{}) {
  OtherFunc(value...)
}

func main() {
  MyFunc( new(Model), new(Mode2) );
}

The problem is that OtherFunc only allow &value, &value, etc as parameter. Have some way to pass those values like OtherFunc(&value...)?

Answer 1

I'm not sure this will solve your problem entirely however, the exact thing you requested is a feature in the language. You just have to use composite-literal syntax for instantiation instead of new. So you could do this to pass pointers; MyFunc( &Model{}, &Mode2{} )

Thing is, you're still going to be dealing with an interface{} within MyFunc so I'm not sure that will just be able to call OtherFunc without some unboxing (would probably be a type assertion if you want to get technical).
