Stout code Analysis of the five: UUID class

Source: Internet
Author: User

UUID Universal Unique identification code, widely used in distributed systems, so that all elements have a unique identity.

The UUID class in stout inherits from Boost::uuids::uuid. The API is as follows:

    • Random, which produces a UUID object.
    • Frombytes, generating a UUID object from a byte array
    • FromString, generating a UUID object from a string
    • Tobytes, generating a byte array from the UUID object
    • ToString, generating characters from UUID objects

Nonsense not much to say, on the example code:

#include"stout/uuid.hpp"#include<iostream>intMain () {UUID a=Uuid::random (); UUID b=uuid::frombytes (A.tobytes ()); UUID C=uuid::fromstring (a.tostring ()); Std::cout<<a.tostring ()<<","<<b.tostring ()<<","<< c.tostring () <<Std::endl; return 0;}
