Definition at line 63 of file quuid.h.

enum QUuid::Variant
 

This enum defines the variant of the UUID, which is the scheme which defines the layout of the 128-bits value.

VarUnknown Variant is unknown NCS Reserved for NCS (Network Computing System) backward compatibility DCE Distributed Computing Environment, the scheme used by QUuid Microsoft Reserved for Microsoft backward compatibility (GUID) Reserved Reserved for future definition

Enumeration values:
VarUnknown

Definition at line 30 of file quuid.h.

enum QUuid::Version
 

This enum defines the version of the UUID.

VerUnknown Version is unknown Time Time-based, by using timestamp, clock sequence, and MAC network card address (if available) for the node sections EmbeddedPOSIX DCE Security version, with embedded POSIX UUIDs Name Name-based, by using values from a name for all sections Random Random-based, by using random numbers for all sections

Constructor & Destructor Documentation

QUuid::QUuid (   )  [inline]
 

Creates the null UUID {00000000-0000-0000-0000-000000000000}.

Definition at line 38 of file quuid.h.

uchar  b2,
uchar  b3,
uchar  b4,
uchar  b5,
uchar  b6,
uchar  b7,
uchar  b8
)  [inline]
 

Creates an UUID with the value specified by the parameters, l, w1, w2, b1, b2, b3, b4, b5, b6, b7, b8.

Example: 

  // {67C8770B-44F1-410A-AB9A-F9B5446F13EE}
  QUuid IID_MyInterface( 0x67c8770b, 0x44f1, 0x410a, 0xab, 0x9a, 0xf9, 0xb5, 0x44, 0x6f, 0x13, 0xee )

Definition at line 42 of file quuid.h.

QUuid::QUuid (  const QUuid &  orig  )  [inline]
 

Creates a copy of the QUuid orig.

Definition at line 56 of file quuid.h.

References data1, data2, data3, data4, and i.

QUuid::QUuid (  const QString &  text  ) 
 

Creates a QUuid object from the string text. Right now, the function can only convert the format {12345678-1234-1234-1234-123456789ABC} and will create the null UUID when the conversion fails.

Member Function Documentation

QUuid QUuid::createUuid (   )  [static]
 

Returns a new UUID of DCE variant, and Random type. The UUIDs generated are based on the platform specific pseudo-random generator, which is usually not a cryptographic-quality random number generator. Therefore, a UUID is not guaranteed to be unique cross application instances.

On Windows, the new UUID is extremely likely to be unique on the same or any other system, networked or not.
