parameters of the golang method, such as the following sample code:
question:
1. Is there a relationship between the parameter an of the foo () method and the an in the main () function?
2. The an in the foo () method doesn"t seem to be used. What does it mean?
in golang, type can be compared to classes in an object-oriented language; variables of this type can be compared to objects in an object-oriented language.
An inmain is the object you instantiate; an in foo is equivalent to this (that is, the current object). You can imagine a scenario: what if you want to use Name in foo?
if you don't understand, go ahead and ask in the comments below. I may not describe it well here, because I haven't figured out how to describe it for the time being
. func (an A) foo () {}
this is a grammatical sugar, which translates to
func foo (an A) {
}
A here can be any name, usually we use this, to pass parameters using pointers.
func (this * A) foo () {}
