Alternative for function overloading in Go?
go, overloading
Solution
Neither function overloading nor optional arguments are directly supported. You could work around them building your own arguments struct. I mean like this (untested, may not work...) EDIT: now tested...
package main
import "fmt"
func main() {
args:=NewMyArgs("a","b") // filename is by default "c"
args.SetFileName("k")
ret := Compresser(args)
fmt.Println(ret)
}
func Compresser(args *MyArgs) string {
return args.dstFilePath + args.srcFilePath + args.fileName
}
// a struct with your arguments
type MyArgs struct
{
dstFilePath, srcFilePath, fileName string
}
// a "constructor" func that gives default values to args
func NewMyArgs(dstFilePath string, srcFilePath string) *MyArgs {
return &MyArgs{
dstFilePath: dstFilePath,
srcFilePath:srcFilePath,
fileName :"c"}
}
func (a *MyArgs) SetFileName(value string){
a.fileName=value;
}
Problem
Is it possible to work similar way like the function overloading or optional parameter in C# using Golang? Or maybe an alternative way?
