You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: sortable.pb.go
    path of file: ./repos/gitkube/vendor/github.com/gogo/protobuf/test/importduplicate/sortkeys
    
    the code of the file until where you have to start completion: // Code generated by protoc-gen-gogo. DO NOT EDIT.
// source: sortkeys/sortable.proto

package sortkeys

import proto "github.com/gogo/protobuf/proto"
import fmt "fmt"
import math "math"
import _ "github.com/gogo/protobuf/gogoproto"

import bytes "bytes"

import strings "strings"
import reflect "reflect"

// Reference imports to suppress errors if they are not otherwise 
    
func (this *Object) Equal(that interface{}) bool {
	if that == nil {
		return this == nil
	}

	that1, ok := that.(*Object)
	if !ok {
		that2, ok := that.(Object)
		if ok {
			that1 = &that2
		} else {
			return false
		}
	}
	if that1 == nil {
		return this == nil
	} else if this == nil {
		return false
	}
	if !bytes.Equal(this.XXX_unrecognized, that1.XXX_unrecognized) {
		return false
	}
	return true
}
