Go object auto mapper

Go AutoMapper

This repository is an extension or fork edition of stroiman/go-automapper

Go-automapper can automatically map data between different types with identically named fields in GO. Useful for initializing DTO types from build in data.

Extension

• This package only use MapLoose function of stroiman/go-automapper to avoid any kind failure when mapping into destination type.
• This package allows to pass a callback function while invoking Map function to map unknown fields of destination object

• Object - Object Mapping

type A struct {
  Name  string

type B struct {
  Name  string
  Phone string
  Email string
}

a := &A{Name: "Tony", Phone: "12355"}
b := &B{}

automapper.Map(a, b, func(src *A, dst *B) {
  dst.Email = "[e-mail]"
})

• Slice - Slice Mapping

type A struct {
  Name string
}

type B struct {
  ID   int
  Name string
}

a1 := &A{Name: "One"}
a2 := &A{Name: "Two"}

aSlice := []*A{a1, a2}
bSlice := []*B{}

automapper.Map(aSlice, &bSlice, func(idx int, src *A, dst *B) {
  t.Log(idx, src, dst)
  dst.ID = idx + 1
})
