using module .\Technology.psm1 <# .SYNOPSIS This class describes a TechnologyVersion .DESCRIPTION The TechnologyVersion class describes a TechnologyVersion, the definition of the specific version of the application or portion of an application that the Stig applies to. The TechnologyVersion is one of a few Technology focused classes that work together to form a complete description of the Stig required by the user or application creating the StigData instance. .EXAMPLE $technologyVersion = [TechnologyVersion]::new([string] $Name, [Technology] $Technology) .NOTES This class requires PowerShell v5 or above. #> Class TechnologyVersion { #region Properties <# .DESCRIPTION The name of a version of technology of the Stig to select #> [string] $Name <# .DESCRIPTION The Technology instance for the selected version #> [Technology] $Technology <# .DESCRIPTION The available versions for each technology currently in PowerStig #> static $ValidateSet = @" Windows = All, 2012R2 SQL = Server2012 "@ #endregion Properties #region Constructors <# .SYNOPSIS Parameterless constructor .DESCRIPTION A parameterless constructor for TechnologyVersion. To be used only for build/unit testing purposes as Pester currently requires it in order to test static methods on powershell classes .RETURN TechnologyVersion #> TechnologyVersion() { Write-Warning "This constructor is for build testing only." } <# .SYNOPSIS Constructor .DESCRIPTION A constructor for TechnologyVersion.
