Why method overloading does not work inside another method?
In the class or object body, this works:
def a(s:String) {}
def a(s:Int) {}
B开发者_C百科ut if it is placed inside another method, it does not compile:
def something() {
def a(s:String) {}
def a(s:Int) {}
}
Why is it so?
Note that you can achieve the same result by creating an object:
def something() {
object A {
def a(s:String) {}
def a(i: Int) {}
}
import A._
a("asd")
a(2)
}
In your example, you define local functions. In my example, I'm declaring methods. Static overloading is allowed for objects, classes and traits.
I don't know why it's not allowed for local functions but my guess is that overloading is a possible source of error and is probably not very useful inside a code block (where presumably you can use different names for in that block scope). I assume it's allowed in classes because it's allowed in Java.
