function Get-Blank { <# .SYNOPSIS Get-Blank returns a blank object that represents no value, and is considered equal to no other object or value. .DESCRIPTION Get-Blank returns an object of type [Blank] as defined in the PSKoans module. This object is not equivalent to any other type of object, including itself, when compared with a standard `-eq` comparison. The only exception, which is unavoidable, is that it is considered equal to $true when $true is on the left-hand side of the comparison. Tthis kind of comparison may sometimes need to be carefully avoided when framing a koan assertion. For instance, the following assertion WILL pass, although it should not: ____ | Should -BeTrue .EXAMPLE __ | Should -Be (4 + 1) .EXAMPLE $Date = Get-Date $____ | Should -Be $Date .EXAMPLE $Num = Get-Random ____ | Should -Not -Be $num #> [CmdletBinding(HelpUri = 'https://github.com/vexx32/PSKoans/tree/master/docs/Get-Blank.md')] [OutputType('Blank')] [Alias('__', '____', 'FILL_ME_IN')] param( # Used to capture the input in a pipeline context, to avoid erroring out in those contexts. [Parameter(ValueFromPipeline, DontShow)] [object] ${|PipeInput}, # Used to capture parameter names and arguments when used as a substitute for any other cmdlet. [Parameter(ValueFromRemainingArguments, DontShow)] [object[]] ${|ParameterInput} ) Write-Verbose "I AIN'T DOIN' NOTHIN'!!!" return [Blank]::New() } |
