Usage

package main

import (
    "fmt"
    "github.com/hollson/kkmap"
)

// define a kkmap object
type TcpPacket struct {
    UUID      string

    return t.UUID
}

func (t *TcpPacket) Key2() interface{} {
    return t.RemoteUrl
}

    // create a kkmap
    kk := kkmap.NewMap()
    kk.Set(&TcpPacket{
