This is the first of the three tips showing you how a PowerShell function can accept data via pipeline or parameter.
In part 1, the function processes the incoming information in real-time. This minimizes memory consumption and provides rapid results:
#requires -Version 2 function Process-Data { param ( [Parameter(Mandatory=$true, ValueFromPipeline=$true)] [Object[]] $Object ) process { foreach ($element in $Object) { "Processing received element $element..." } } }
Note how you can call the function via parameter:
PS C:\> Process-Data -Object 1 Processing received element 1... PS C:\> Process-Data -Object 1,2,3,4 Processing received element 1... Processing received element 2... Processing received element 3... Processing received element 4...
You can also pipe information via pipeline:
PS C:\> 1..4 | Process-Data Processing received element 1... Processing received element 2... Processing received element 3... Processing received element 4...
