.SH DESCRIPTION
The QUuid class defines a Universally Unique Identifier (UUID).
.PP
For objects or declarations that need to be uniquely identified, UUIDs (also known as GUIDs) are widely used in order to assign a fixed and easy to compare value to the object or declaration. The 128-bit value of a UUID is generated by an algorithm that guarantees that the value is unique.
.PP
In Qt, UUIDs are wrapped by the QUuid struct which provides convenience functions for handling UUIDs. Most platforms provide a tool to generate new UUIDs, for example, uuidgen and guidgen.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QUuid::QUuid ()"
Creates the null UUID {00000000-0000-0000-0000-000000000000}.
.SH "QUuid::QUuid ( uint l, ushort w1, ushort w2, uchar b1, uchar b2, uchar b3, uchar b4, uchar b5, uchar b6, uchar b7, uchar b8 )"
Creates a UUID with the value specified by the parameters, \fIl\fR, \fIw1\fR, \fIw2\fR, \fIb1\fR, \fIb2\fR, \fIb3\fR, \fIb4\fR, \fIb5\fR, \fIb6\fR, \fIb7\fR, \fIb8\fR.
.PP
Example:
.PP
.nf
.br
    // {67C8770B-44F1-410A-AB9A-F9B5446F13EE}
.br
    QUuid IID_MyInterface( 0x67c8770b, 0x44f1, 0x410a, 0xab, 0x9a, 0xf9, 0xb5, 0x44, 0x6f, 0x13, 0xee )
.br
.fi
.SH "QUuid::QUuid ( const QUuid & orig )"
Creates a copy of the QUuid \fIorig\fR.
.SH "QUuid::QUuid ( const QString & text )"
Creates a QUuid object from the string \fItext\fR. The function can only convert a string in the format {HHHHHHHH-HHHH-HHHH-HHHH-HHHHHHHHHHHH} (where 'H' stands for a hex digit), and will create the null UUID if the conversion fails.
.SH "bool QUuid::isNull () const"
Returns TRUE if this is the null UUID {00000000-0000-0000-0000-000000000000}; otherwise returns FALSE.
.SH "QUuid::operator QString () const"
Returns the string representation of the uuid.
.PP
See also toString().
.SH "bool QUuid::operator!= ( const QUuid & other ) const"
Returns TRUE if this QUuid and the \fIother\fR QUuid are different; otherwise returns FALSE.
.SH "QUuid & QUuid::operator= ( const QUuid & uuid )"
Assigns the value of \fIuuid\fR to this QUuid object.
.SH "bool QUuid::operator== ( const QUuid & other ) const"
Returns TRUE if this QUuid and the \fIother\fR QUuid are identical; otherwise returns FALSE.
.SH "QString QUuid::toString () const"
QString QUuid::toString() const
.PP
Returns the string representation of the uuid.
.SH RELATED FUNCTION DOCUMENTATION
.SH "QDataStream & operator<< ( QDataStream & s, const QUuid & id )"
Writes the uuid \fIid\fR to the datastream \fIs\fR.
.SH "QDataStream & operator>> ( QDataStream & s, QUuid & id )"
Reads uuid from from the stream \fIs\fR into \fIid\fR.
