type

Version

@Serializable { simple=true } const class Version : Obj

Version is defined as a list of decimal digits separated by the dot. Convention for Fantom pods is a four part version format of major.minor.build.patch.

constructors

fromStr	Parse a string representation into a Version.
make	Construct with list of integer segments.

fields

defVal	Default value is "0".

methods

build	Get the third segment which represents the build number.
compare	Compare from from most significant segment to least significant segment.
equals	Return true if equal segments.
hash	Return toStr.hash
major	Get the first, most significant segment which represents the major version.
minor	Get the second segment which represents the minor version.
patch	Get the fourth segment which represents the patch number.
segments	Get a readonly list of the integer segments.
toStr	The string format is equivalent to segments.join(".")

Slot Details

build

Int? build()

Get the third segment which represents the build number. Return null if version has less than three segments.

compare

virtual override Int compare(Obj obj)

Compare from from most significant segment to least significant segment.

Examples:

1.6 > 1.4
2.0 > 1.9
1.2.3 > 1.2
1.11 > 1.9.3

defVal

const static Version defVal

Default value is "0".

equals

virtual override Bool equals(Obj? obj)

Return true if equal segments.

fromStr

static new fromStr(Str version, Bool checked := true)

Parse a string representation into a Version. If invalid format and checked is false return null, otherwise throw ParseErr.

hash

virtual override Int hash()

Return toStr.hash

major

Int major()

Get the first, most significant segment which represents the major version.

make

static new make(Int[] segments)

Construct with list of integer segments. Throw ArgErr if segments is empty or contains negative numbers.

minor

Int? minor()

Get the second segment which represents the minor version. Return null if version has less than two segments.

patch

Int? patch()

Get the fourth segment which represents the patch number. Return null if version has less than four segments.

segments

Int[] segments()

Get a readonly list of the integer segments.

toStr

virtual override Str toStr()

The string format is equivalent to segments.join(".")
