Detailed Description

While there are many terms used to describe each segment in a typical four part version number, the fourth segment in this class is dubbed "Nano Version" to stay consistent with the naming scheme of QVersionNumber.

Constructor & Destructor Documentation

VersionNumber() [1/8]

Qx::VersionNumber::VersionNumber	(	int	maj,
		int	min,
		int	mic,
		int	nan )

Constructs a VersionNumber consisting of the major, minor, micro, and nano version numbers maj, min, mic, and nan, respectively.

VersionNumber() [2/8]

Qx::VersionNumber::VersionNumber	(	int	maj,
		int	min,
		int	mic )

Constructs a VersionNumber consisting of the major, minor and micro version numbers maj, min and mic, respectively.

VersionNumber() [3/8]

Qx::VersionNumber::VersionNumber	(	int	maj,
		int	min )

Constructs a VersionNumber consisting of the major and minor version numbers maj and min, respectively.

VersionNumber() [4/8]

Qx::VersionNumber::VersionNumber

(

int

maj

)

Constructs a VersionNumber consisting of just the major version number maj.

VersionNumber() [5/8]

Qx::VersionNumber::VersionNumber

(

std::initializer_list< int >

args

)

Construct a version number from the std::initializer_list specified by args.

VersionNumber() [6/8]

Qx::VersionNumber::VersionNumber

(

QList< int > &&

seg

)

Move-constructs a version number from the list of numbers contained in seg.

VersionNumber() [7/8]

Qx::VersionNumber::VersionNumber

(

const QList< int > &

seg

)

Construct a version number from the std::initializer_list specified by args.

VersionNumber() [8/8]

Qx::VersionNumber::VersionNumber

(

)

Produces a null version.

Member Function Documentation

commonPrefix()

VersionNumber Qx::VersionNumber::commonPrefix ( const VersionNumber & v1, const VersionNumber & v2 )

static

Returns a version number that is a parent version of both v1 and v2.

See also

isPrefixOf()

first()

VersionNumber Qx::VersionNumber::first

(

qsizetype

n

)

const

Returns a version number that contains the first n segments of this version number, or all segments if there are less than n available.

See also

commonPrefix().

fromString() [1/3]

VersionNumber Qx::VersionNumber::fromString ( const QString & string, int * suffixIndex = nullptr )

static

Constructs a VersionNumber from a specially formatted string of non-negative decimal delimited by a period (.).

Once the numerical segments have been parsed, the remainder of the string is considered to be the suffix string. The start index of that string will be stored in suffixIndex if it is not null.

See also

isNull().

fromString() [2/3]

VersionNumber Qx::VersionNumber::fromString ( QLatin1String string, int * suffixIndex = nullptr )

static

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

fromString() [3/3]

VersionNumber Qx::VersionNumber::fromString ( QStringView string, int * suffixIndex = nullptr )

static

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

nanoVersion()

int Qx::VersionNumber::nanoVersion

(

)

const

Returns the nano version number, that is, the fourth segment. This function is equivalent to segmentAt(3). If this VersionNumber object is null, this function returns 0.

See also

isNull(), segmentAt().

normalized()

VersionNumber Qx::VersionNumber::normalized

(

qsizetype

min = 0

)

const

Returns an equivalent version number but with all trailing zeros removed.

If min is greater than 0, at least that many segments, up to segmentCount(), are kept in the resultant version number, even if some of them are trailing zeros.

VersionNumber v1(3,0,0,0);
VersionNumber v2(10,1,0);
VersionNumber v3(1,2,0,0);
VersionNumber n1 = v1.normalized(2);
VersionNumber n2 = v2.normalized(8);
VersionNumber n3 = v3.normalized();
// n1 is 3.0
// n2 is 10.1.0
// n3 is 1.2
