Detailed Description

The Version class represents a version number in the format "1.42.7".

Rules for a version number:

• Minimum count of numbers: 1 (example: "15")
• Maximum count of numbers: 10 (example: "31.41.5.926.5358.97.9.3.238.462")
• Minimum count of digits of a number: 1
• Maximum count of digits of a number: 5

So the lowest possible version is "0", and the highest possible version is "99999.99999.99999.99999.99999.99999.99999.99999.99999.99999".

Leading zeros in numbers are ignored: "002.0005" will be converted to "2.5" Trailing zero numbers are ignored: "2.5.0.0" will be converted to "2.5"

Note

This class guarantees that only Version objects representing a valid version number can be created! If you need a nullable Version, use std::optional<librepcb::Version> instead.

Constructor & Destructor Documentation

Version() [1/3]

Version ( )

delete

Default constructor (disabled to avoid creating invalid versions)

Version() [2/3]

Version ( const Version &  other )

inlinenoexcept

Copy constructor.

Parameters

other

Another librepcb::Version object

~Version()

~Version ( )

defaultnoexcept

Destructor

Version() [3/3]

Version ( const QVector< uint > &  numbers )

inlineexplicitprivatenoexcept

Member Function Documentation

isPrefixOf()

bool isPrefixOf ( const Version &  other ) const

noexcept

Check if this version is the prefix of another version.

Example: "1.2" is a prefix of "1.2", "1.2.0.1", "1.2.1"

Parameters

other

Another version

Returns

True if "other" starts with the same segments as all segments of this version, otherwise false.

getNumbers()

const QVector< uint > & getNumbers ( ) const

inlinenoexcept

Get the numbers in the version string.

The first item in the list is the major version number.

Returns

Vector of numbers

toStr()

QString toStr ( ) const

noexcept

Get the version as a string in the format "1.2.3".

Returns

The version as a string

Here is the call graph for this function:

Here is the caller graph for this function:

toPrettyStr()

QString toPrettyStr ( int  minSegCount, int  maxSegCount = 10  ) const

noexcept

Get the version as a string with trailing zeros (e.g. "1.2.0")

Parameters

minSegCount	If the version has less segments than specified by this parameter, trailing zeros will be appended. Example: "0.1" gets "0.1.0.0" with minSegCount = 4
maxSegCount	If the version has more segments than specified by this parameter, trailing segments will be omitted. Example: "0.1.2.3.4" gets "0.1" with maxSegCount = 2

Returns

The version as a string

Here is the caller graph for this function:

toComparableStr()

QString toComparableStr ( ) const

noexcept

Get the version as a comparable string (59 characters)

The version will be returned with all 10x5 decimal places: "#####.#####.#####.#####.#####.#####.#####.#####.#####.#####"

This method is useful to compare versions in a database (e.g. SQLite) as you only need a simple string compare.

Returns

The version as a comparable string

Here is the caller graph for this function:

operator=()

Version & operator= ( const Version &  rhs )

inlinenoexcept

operator>()

bool operator> ( const Version &  rhs ) const

inlinenoexcept

Comparison operators.

Parameters

rhs	The other object to compare

Returns

Result of comparing the UUIDs as comparable strings

Here is the call graph for this function:

operator<()

bool operator< ( const Version &  rhs ) const

inlinenoexcept

Here is the call graph for this function:

operator>=()

bool operator>= ( const Version &  rhs ) const

inlinenoexcept

Here is the call graph for this function:

operator<=()

bool operator<= ( const Version &  rhs ) const

inlinenoexcept

Here is the call graph for this function:

operator==()

bool operator== ( const Version &  rhs ) const

inlinenoexcept

operator!=()

bool operator!= ( const Version &  rhs ) const

inlinenoexcept

isValid()

bool isValid ( const QString &  str )

staticnoexcept

Check if a string is a valid version number.

Parameters

str	The string to check

Return values

true	If str is a valid version number
false	If str is not a valid version number

fromString()

Version fromString ( const QString &  str )

static

Create a Version object from a string.

Parameters

str	The version string in the format "1.2.3" (variable count of numbers)

Returns

A valid Version object

Exceptions

Exception

if the string does not contain a valid version number

Here is the call graph for this function:

Here is the caller graph for this function:

tryFromString()

std::optional< Version > tryFromString ( const QString &  str )

staticnoexcept

Try creating a Version object from a string, returning empty optional if invalid.

Parameters

str	Input string

Return values

Version	The created Version object if str was valid
std::nullopt	If str was not a valid version number

Here is the caller graph for this function:
