Struct OSVersion

Represents a version number consisting of major, minor, and point compnents. Version numbers are often written as Major.Minor.Point.

Namespace: UnityEngine.XR.ARKit

Syntax

public struct OSVersion : IEquatable<OSVersion>, IComparable<OSVersion>

Constructors

OSVersion(Int32, Int32, Int32)

Constructs a new version number.

Declaration

public OSVersion(int major, int minor = 0, int point = 0)

Parameters

Type	Name	Description
Int32	major	The major version component
Int32	minor	The minor version component
Int32	point	The point version component

Properties

major

The major version component.

Declaration

public int major { get; }

Property Value

Type	Description
Int32

minor

The minor version component.

Declaration

public int minor { get; }

Property Value

Type	Description
Int32

point

The point version component.

Declaration

public int point { get; }

Property Value

Type	Description
Int32

Methods

CompareTo(OSVersion)

IComparable interface. This is useful for sorting routines.

Declaration

public int CompareTo(OSVersion version)

Parameters

Type	Name	Description
OSVersion	version	The other version to compare to.

Returns

Type	Description
Int32	-1 if this OSVersion is less than version, 0 if they are equal, or 1 if this is greater.

Equals(Object)

Compares for equality.

Declaration

public override bool Equals(object obj)

Parameters

Type	Name	Description
Object	obj	The object to compare against.

Returns

Type	Description
Boolean	Returns false if obj is null or is not of type OSVersion. Otherwise, returns the same value as Equals(OSVersion).

Overrides

ValueType.Equals(Object)

Equals(OSVersion)

Compares for equality. The three version components are compared against other's.

Declaration

public bool Equals(OSVersion other)

Parameters

Type	Name	Description
OSVersion	other	The OSVersion to compare for equality.

Returns

Type	Description
Boolean	True if other has the same major, minor, and point values.

GetHashCode()

Generates a hash code suitable for use in a HashSet or Dictionary.

Declaration

public override int GetHashCode()

Returns

Type	Description
Int32	A hash code. The same OSVersion will produce the same hash code.

Overrides

ValueType.GetHashCode()

Parse(String)

Parses a string which contains a version number of the form X.Y.Z somewhere in the string. If multiple such substrings exists, the first is used. The parser stops when either 3 components have been identified, or when less than 3 components have been identified and the next character is not a period (".") or a digit (0-9). If version is null or the empty string, this method returns the version 0.0.0

Declaration

public static OSVersion Parse(string version)

Parameters

Type	Name	Description
String	version	The string to parse.

Returns

Type	Description
OSVersion	A new OSVersion representing version.

ToString()

Generates a string representation of the version.

Declaration

public override string ToString()

Returns

Type	Description
String	A string in the form major.minor.point.

Overrides

ValueType.ToString()

Operators

Equality(OSVersion, OSVersion)

Tests whether lhs is the same version as rhs. This is the same as Equals(OSVersion).

Declaration

public static bool operator ==(OSVersion lhs, OSVersion rhs)

Parameters

Type	Name	Description
OSVersion	lhs	The left-hand side of the comparison.
OSVersion	rhs	The right-hand side of the comparison.

Returns

Type	Description
Boolean	true if lhs is the same version as rhs; otherwise, false.

GreaterThan(OSVersion, OSVersion)

Tests whether lhs is a later version compared to rhs.

Declaration

public static bool operator>(OSVersion lhs, OSVersion rhs)

Parameters

Type	Name	Description
OSVersion	lhs	The left-hand side of the comparison.
OSVersion	rhs	The right-hand side of the comparison.

Returns

Type	Description
Boolean	true if lhs is a later version compared to rhs; otherwise, false.

GreaterThanOrEqual(OSVersion, OSVersion)

Tests whether lhs is the same or a later version compared to rhs.

Declaration

public static bool operator >=(OSVersion lhs, OSVersion rhs)

Parameters

Type	Name	Description
OSVersion	lhs	The left-hand side of the comparison.
OSVersion	rhs	The right-hand side of the comparison.

Returns

Type	Description
Boolean	true if lhs is the same or a later version compared to rhs; otherwise, false.

Inequality(OSVersion, OSVersion)

Tests whether lhs is a different version from rhs.

Declaration

public static bool operator !=(OSVersion lhs, OSVersion rhs)

Parameters

Type	Name	Description
OSVersion	lhs	The left-hand side of the comparison.
OSVersion	rhs	The right-hand side of the comparison.

Returns

Type	Description
Boolean	true if lhs is a different version from rhs; otherwise, false.

LessThan(OSVersion, OSVersion)

Tests whether lhs is an earlier version compared to rhs.

Declaration

public static bool operator <(OSVersion lhs, OSVersion rhs)

Parameters

Type	Name	Description
OSVersion	lhs	The left-hand side of the comparison.
OSVersion	rhs	The right-hand side of the comparison.

Returns

Type	Description
Boolean	true if lhs is an earlier version compared to rhs; otherwise, false.

LessThanOrEqual(OSVersion, OSVersion)

Tests whether lhs is the same or an earlier version compared to rhs.

Declaration

public static bool operator <=(OSVersion lhs, OSVersion rhs)

Parameters

Type	Name	Description
OSVersion	lhs	The left-hand side of the comparison.
OSVersion	rhs	The right-hand side of the comparison.

Returns

Type	Description
Boolean	true if lhs is the same or an earlier version compared to rhs; otherwise, false.
