Set the parameter as an interface or a list of interfaces

I am new to Go and there are some utilities that I am not getting yet

For example, I have a function that can be called like this:

myVar.InitOperation("foo",Operator.EQUAL,"bar")
myVar.InitOperation("foo",Operator.INCLUDE,[]interface{}{"baz",1,"boo"})
myVar.InitOperation("foo",Operator.GREATER_THAN,1)

      

        
        
        
      

    

So, I declared this function as:

func InitOperation(attr string, operator Operator, value interface{}){
    if operator.String() == "BAR"{
        doSomething(attr,operator,value)
    } else if (operator.String() == "INCLUDE" {
        doSomethingElse(attr,operator,value)
    }
    // And so on regarding to the case
}

      

        
        
        
      

    

The thing is, when I pass in a string or an integer it happens fine, but when I pass in an array, it is parsed as one element.

In my function, doSomethingElse

I'm trying to iterate over values

, and as you can guess, I have a bug.

Ok, I just installed values

as []interface{}

, not interface{}

. Everything goes well here, but when I call doSomething

it is parsed as [[myValue]]

, which is logical, but not what I expect.

My question is, is there a way to pass either []interface{}

, interface{}

which can be red as a value or an array of relevant values?

Thank!
