Exceptions

Exception type Condition

Remarks

This method must be overridden in any cmdlet that does pre-processing. The runspace calls this method once for each instance of the cmdlet in the pipeline.

The override of this method does not have to be re-entrant; this method does not have to be callable simultaneously with the ProcessRecord method or the EndProcessing method. None of these input processing methods will be called as long as any one of them is running in a cmdlet instance. However, there is no guarantee that all calls to these methods will occur on the same thread.

For more information about when the Windows PowerShell runtime calls this method, see Cmdlet Lifecycle.
