| Exception type | Condition |
|---|
| Exception | The override of this method can throw any exception that is required. |
This method must be overridden in any cmdlet that does preprocessing. 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 reentrant; this method does not have to be callable simultaneously with the ProcessRecord method or the EndProcessing method. None of these input processing methods are called if 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.
For more information about cmdlets, see >Windows PowerShell Cmdlets.
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
