[go-nuts] Re: Struct overloading method issue
Maybe I misunderstood your need, but I would just call the A method
directly like below.
type A struct{}
func (a *A) private() {}
func (a *A) Public() {
a.private()
}
type B struct {A}
func (b *B) private() {
b.A.private()
}
bi := B{}
b.Public() //calls the A.Private

[go-nuts] Re: Struct overloading method issue
I solved it for now using composition and Constructors
func NewA() {
r := A{}
r.private = privateForA
}
func NewB(){
r := B{}
r.private = privateForB
}
I saw using constructors in a few builtin packages so I guess is ok.
