org.jsweet.transpiler.OverloadScanner

public class OverloadScanner
extends AbstractTreeScanner

This AST scanner detects method overloads and gather them into OverloadScanner.Overload objects. "Valid" overloads are the cases where the overload calls the overloaded method with some constants. It can then be translated as a unique method containing default parameter values. "Wrong" overloads are all the other cases. A core generic untyped signature is generated that englobles all the overloads and dispatch to the implementations depending on the parameter types.
