Detailed Description

A universally unique identifier (UUID).

An alternate term for UUID is “globally unique identifier” (GUID), used primarily by Microsoft.

A UUID is a unique 128-bit number specified by RFC 4122.

This is a standard-layout structure.

Constructor & Destructor Documentation

UUID() [1/2]

crashpad::UUID::UUID ( InitializeWithNewTag  )

explicit

Initializes the UUID using a standard system facility to generate the value.

CHECKs on failure with a message logged.

UUID() [2/2]

crashpad::UUID::UUID ( const uint8_t *  bytes )

explicit

Initializes the UUID from a sequence of bytes.

bytes is taken as a UUID laid out in big-endian format in memory. On little-endian machines, appropriate byte-swapping will be performed to initialize an object’s data members.

Parameters

[in]

bytes

A buffer of exactly 16 bytes that will be assigned to the UUID.

Member Function Documentation

InitializeFromBytes()

void crashpad::UUID::InitializeFromBytes

(

const uint8_t *

bytes

)

Initializes the UUID from a sequence of bytes.

bytes is taken as a UUID laid out in big-endian format in memory. On little-endian machines, appropriate byte-swapping will be performed to initialize an object’s data members.

Parameters

[in]

bytes

A buffer of exactly 16 bytes that will be assigned to the UUID.

InitializeFromString()

bool crashpad::UUID::InitializeFromString

(

const base::StringPiece &

string

)

Initializes the UUID from a RFC 4122 §3 formatted string.

Parameters

[in]

string

A string of the form "00112233-4455-6677-8899-aabbccddeeff".

Returns

true if the string was formatted correctly and the object has been initialized with the data. false if the string could not be parsed, with the object state untouched.

InitializeFromSystemUUID()

void crashpad::UUID::InitializeFromSystemUUID

(

const ::UUID *

system_uuid

)

Initializes the UUID from a system UUID or GUID structure.

Parameters

[in]

system_uuid

A system UUID or GUID structure.

InitializeWithNew()

bool crashpad::UUID::InitializeWithNew

(

)

Initializes the UUID using a standard system facility to generate the value.

Returns

true if the UUID was initialized correctly, false otherwise with a message logged.

ToString()

std::string crashpad::UUID::ToString

(

)

const

Formats the UUID per RFC 4122 §3.

Returns

A string of the form "00112233-4455-6677-8899-aabbccddeeff".
