function Compare-Property { <# .SYNOPSIS Helper function simplifying the changes processing. .DESCRIPTION Helper function simplifying the changes processing. .PARAMETER Property The property to use for comparison. .PARAMETER Configuration The object that was used to define the desired state. .PARAMETER ADObject The AD Object containing the actual state. .PARAMETER Changes An arraylist where changes get added to. The content of -Property will be added if the comparison fails. .PARAMETER Resolve Whether the value on the configured object's property should be string-resolved. .PARAMETER ADProperty The property on the ad object to use for the comparison. If this parameter is not specified, it uses the value from -Property. .EXAMPLE PS C:\> Compare-Property -Property Description -Configuration $ouDefinition -ADObject $adObject -Changes $changes -Resolve Compares the description on the configuration object (after resolving it) with the one on the ADObject and adds to $changes if they are inequal. #> [CmdletBinding()] param ( [Parameter(Mandatory = $true)] [string] $Property, [Parameter(Mandatory = $true)] [object] $Configuration, [Parameter(Mandatory = $true)] [object] $ADObject, [Parameter(Mandatory = $true)] [AllowEmptyCollection()] [System.Collections.ArrayList] $Changes, [switch] $Resolve, [string] $ADProperty ) begin { if (-not $ADProperty) { $ADProperty = $Property } } process { $propValue = $Configuration.$Property if ($Resolve) { $propValue = $propValue | Resolve-String } if (($propValue -is [System.Collections.ICollection]) -and ($ADObject.$ADProperty -is [System.Collections.ICollection])) { if (Compare-Object $propValue $ADObject.$ADProperty) { $null = $Changes.Add($Property) } } elseif ($propValue -ne $ADObject.$ADProperty) { $null = $Changes.Add($Property) } } } |
