#include <RandomUuid.h>

Public Types

using Serialized = std::array< uint8_t, 128/8 >
 UUID representation independent of machine byte-order architecture.
 

Public Member Functions

 RandomUuid ()
 creates a new unique ID (i.e. not a "nil UUID" in RFC 4122 terminology)
 
 RandomUuid (const Serialized &)
 imports a UUID value that was exported using the serialize() API
 
 RandomUuid (RandomUuid &&)=default
 
RandomUuid & operator= (RandomUuid &&)=default
 
RandomUuid & operator= (const RandomUuid &)=delete
 
Serialized serialize () const
 exports UUID value; suitable for long-term storage
 
bool operator== (const RandomUuid &) const
 
bool operator!= (const RandomUuid &other) const
 
RandomUuid clone () const
 creates a UUID object with the same value as this UUID
 
void print (std::ostream &os) const
 writes a human-readable representation
 

Private Member Functions

 RandomUuid (const RandomUuid &)=default
 
char * raw ()
 read/write access to storage bytes
 
const char * raw () const
 read-only access to storage bytes
 
bool sane () const
 whether this (being constructed) object follows UUID version 4 variant 1 format

Detailed Description

128-bit Universally Unique IDentifier (UUID), version 4 (variant 1) as defined by RFC 4122. These UUIDs are generated from pseudo-random numbers.
