Detailed Description

A universally unique 128-bit identifier.

This class generates very random unique numbers. It's vanishingly unlikely that two identical UUIDs would ever be created by chance. The values are formatted to meet the RFC 4122 version 4 standard.

The class includes methods for saving the ID as a string or as raw binary data.

Constructor & Destructor Documentation

Uuid() [1/4]

juce::Uuid::Uuid

(

)

Creates a new unique ID, compliant with RFC 4122 version 4.

~Uuid()

juce::Uuid::~Uuid ( )

noexcept

Destructor.

Uuid() [2/4]

juce::Uuid::Uuid ( const Uuid & other )

noexcept

Creates a copy of another UUID.

Uuid() [3/4]

juce::Uuid::Uuid

(

const String &

uuidString

)

Creates an ID from an encoded string version.

toString

Uuid() [4/4]

juce::Uuid::Uuid ( const uint8 * rawData )

noexcept

Creates a UUID from a 16-byte array.

getRawData

Member Function Documentation

compare()

int juce::Uuid::compare ( Uuid other ) const

privatenoexcept

getClockSeqAndReserved()

uint8 juce::Uuid::getClockSeqAndReserved ( ) const

noexcept

Returns the clock-seq-and-reserved section of the UUID.

getClockSeqLow()

uint8 juce::Uuid::getClockSeqLow ( ) const

noexcept

Returns the clock-seq-low section of the UUID.

getHexRegion()

String juce::Uuid::getHexRegion ( int start, int length ) const

private

getNode()

uint64 juce::Uuid::getNode ( ) const

noexcept

Returns the node section of the UUID.

getRawData()

const uint8 * juce::Uuid::getRawData ( ) const

inlinenoexcept

Returns a pointer to the internal binary representation of the ID.

This is an array of 16 bytes. To reconstruct a Uuid from its data, use the constructor or operator= method that takes an array of uint8s.

getTimeHighAndVersion()

uint16 juce::Uuid::getTimeHighAndVersion ( ) const

noexcept

Returns the time-high-and-version section of the UUID.

getTimeLow()

uint32 juce::Uuid::getTimeLow ( ) const

noexcept

Returns the time-low section of the UUID.

getTimeMid()

uint16 juce::Uuid::getTimeMid ( ) const

noexcept

Returns the time-mid section of the UUID.

hash()

uint64 juce::Uuid::hash ( ) const

noexcept

Returns a hash of the UUID.

isNull()

bool juce::Uuid::isNull ( ) const

noexcept

Returns true if the ID is zero.

null()

Uuid juce::Uuid::null ( )

staticnoexcept

Returns a null Uuid object.

operator!=()

bool juce::Uuid::operator!= ( const Uuid & other ) const

noexcept

operator<()

bool juce::Uuid::operator< ( const Uuid & other ) const

noexcept

operator<=()

bool juce::Uuid::operator<= ( const Uuid & other ) const

noexcept

operator=() [1/3]

Uuid & juce::Uuid::operator=

(

const String &

uuidString

)

Copies from a stringified UUID. The string passed in should be one that was created with the toString() method.

operator=() [2/3]

Uuid & juce::Uuid::operator= ( const uint8 * rawData )

noexcept

Sets this UUID from 16-bytes of raw data.

operator=() [3/3]

Uuid & juce::Uuid::operator= ( const Uuid & other )

noexcept

Copies another UUID.

operator==()

bool juce::Uuid::operator== ( const Uuid & other ) const

noexcept

operator>()

bool juce::Uuid::operator> ( const Uuid & other ) const

noexcept

operator>=()

bool juce::Uuid::operator>= ( const Uuid & other ) const

noexcept

toDashedString()

String juce::Uuid::toDashedString

(

)

const

Returns a stringified version of this UUID, separating it into sections with dashes.

Returns

a string in the format: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

toString()

String juce::Uuid::toString

(

)

const

Returns a stringified version of this UUID.

A Uuid object can later be reconstructed from this string using operator= or the constructor that takes a string parameter.

Returns

a 32 character hex string.
