Lets say that I have the following:
type A Interface{
....
}
//Implements A
type B struct{
....
}
//Imlements A
type C struct{
....
}
And now I have a function which accepts variable of type A as an argument:
func Foo(obj A){
if A is B{
....
}else if A is C{
....
}
}
And a main function:
func main(){
b := B{}
Foo(b)
}
How can I check if the argument passed to the function is actually type B?
Use a type switch as mentioned the tour page linked by @CeriseLimón.
func Foo(v A) {
switch v := v.(type) {
case B:
// It's a B
case C:
// It's a C
}
}
