By default the function returns any objects with properties that are Equal (-eq) to the value of the parameter. To give you more flexibility you can modify the operator by using -NotEquals [ParameterName[]], -LessThan [ParameterName[]] and so on. Possible operators for all parameters are: -NotEquals -GreaterThan -GreaterThanOrEqual -LessThan -LessThanOrEquals Additional operators for [String] parameters are: -Like (supports * or % as wildcards) -NotLike -BeginsWith -EndsWith -Contains Properties with picklists are: Entities that have fields that refer to the base entity of this CmdLet: .INPUTS Nothing. This function only takes parameters. .OUTPUTS [Autotask.ChangeRequestLink[]]. This function outputs the Autotask.ChangeRequestLink that was returned by the API. .EXAMPLE Get-AtwsChangeRequestLink -Id 0 Returns the object with Id 0, if any. .EXAMPLE Get-AtwsChangeRequestLink -ChangeRequestLinkName SomeName Returns the object with ChangeRequestLinkName 'SomeName', if any. .EXAMPLE Get-AtwsChangeRequestLink -ChangeRequestLinkName 'Some Name' Returns the object with ChangeRequestLinkName 'Some Name', if any. .EXAMPLE Get-AtwsChangeRequestLink -ChangeRequestLinkName 'Some Name' -NotEquals ChangeRequestLinkName Returns any objects with a ChangeRequestLinkName that is NOT equal to 'Some Name', if any. .EXAMPLE Get-AtwsChangeRequestLink -ChangeRequestLinkName SomeName* -Like ChangeRequestLinkName Returns any object with a ChangeRequestLinkName that matches the simple pattern 'SomeName*'. Supported wildcards are * and %. .EXAMPLE Get-AtwsChangeRequestLink -ChangeRequestLinkName SomeName* -NotLike ChangeRequestLinkName Returns any object with a ChangeRequestLinkName that DOES NOT match the simple pattern 'SomeName*'. Supported wildcards are * and %. .LINK New-AtwsChangeRequestLink .LINK Remove-AtwsChangeRequestLink #> [CmdLetBinding(SupportsShouldProcess = $True, DefaultParameterSetName='Filter', ConfirmImpact='None')] Param ( # A filter that limits the number of objects that is returned from the API [Parameter( Mandatory = $true, ValueFromRemainingArguments = $true, ParameterSetName = 'Filter' )] [ValidateNotNullOrEmpty()] [String[]] $Filter, # Follow this external ID and return any external objects [Parameter( ParameterSetName = 'Filter' )] [Parameter( ParameterSetName = 'By_parameters' )] [Alias('GetRef')] [ValidateNotNullOrEmpty()] [ValidateSet('ChangeRequestTicketID', 'ProblemOrIncidentTicketID')] [String] $GetReferenceEntityById, # Return entities of selected type that are referencing to this entity.
