PSCmdlet PSCmdlet PSCmdlet PSCmdlet Class

Definition

Defines members and overrides used by Cmdlets. All Cmdlets must derive from Cmdlet.

Remarks

There are two ways to create a Cmdlet: by deriving from the Cmdlet base class, and by

deriving from the PSCmdlet base class. The Cmdlet base class is the primary means by

which users create their own Cmdlets. Extending this class provides support for the most

common functionality, including object output and record processing.

If your Cmdlet requires access to the MSH Runtime (for example, variables in the session state,

access to the host, or information about the current Cmdlet Providers,) then you should instead

derive from the PSCmdlet base class.

The public members defined by the PSCmdlet class are not designed to be overridden; instead, they

provided access to different aspects of the MSH runtime.

In both cases, users should first develop and implement an object model to accomplish their

task, extending the Cmdlet or PSCmdlet classes only as a thin management layer.

Constructors

PSCmdlet() PSCmdlet() PSCmdlet() PSCmdlet()

Properties

CommandOrigin CommandOrigin CommandOrigin CommandOrigin

This property tells you if you were being invoked inside the runspace or if it was an external request.

(Inherited from InternalCommand)

Gets the instance of session state for the current runspace.

Stopping Stopping Stopping Stopping

Is this command stopping?

Methods

BeginProcessing() BeginProcessing() BeginProcessing() BeginProcessing()

When overridden in the derived class, performs initialization of command execution. Default implementation in the base class just returns.

(Inherited from Cmdlet)
CurrentProviderLocation(String) CurrentProviderLocation(String) CurrentProviderLocation(String) CurrentProviderLocation(String)
EndProcessing() EndProcessing() EndProcessing() EndProcessing()

When overridden in the derived class, performs clean-up after the command execution. Default implementation in the base class just returns.

(Inherited from Cmdlet)
GetResolvedProviderPathFromPSPath(String, ProviderInfo) GetResolvedProviderPathFromPSPath(String, ProviderInfo) GetResolvedProviderPathFromPSPath(String, ProviderInfo) GetResolvedProviderPathFromPSPath(String, ProviderInfo)
GetResourceString(String, String) GetResourceString(String, String) GetResourceString(String, String) GetResourceString(String, String)

Gets the resource string corresponding to baseName and resourceId from the current assembly. You should override this if you require a different behavior.

(Inherited from Cmdlet)
GetUnresolvedProviderPathFromPSPath(String) GetUnresolvedProviderPathFromPSPath(String) GetUnresolvedProviderPathFromPSPath(String) GetUnresolvedProviderPathFromPSPath(String)
GetVariableValue(String) GetVariableValue(String) GetVariableValue(String) GetVariableValue(String)
GetVariableValue(String, Object) GetVariableValue(String, Object) GetVariableValue(String, Object) GetVariableValue(String, Object)
Invoke() Invoke() Invoke() Invoke()

Invoke this cmdlet object returning a collection of results.

(Inherited from Cmdlet)
Invoke<T>() Invoke<T>() Invoke<T>() Invoke<T>()

Returns a strongly-typed enumerator for the results of this cmdlet.

(Inherited from Cmdlet)
ProcessRecord() ProcessRecord() ProcessRecord() ProcessRecord()

When overridden in the derived class, performs execution of the command.

(Inherited from Cmdlet)
ShouldContinue(String, String) ShouldContinue(String, String) ShouldContinue(String, String) ShouldContinue(String, String)

Confirm an operation or grouping of operations with the user. This differs from ShouldProcess in that it is not affected by preference settings or command-line parameters, it always does the query. This variant only offers Yes/No, not YesToAll/NoToAll.

(Inherited from Cmdlet)
ShouldContinue(String, String, Boolean, Boolean) ShouldContinue(String, String, Boolean, Boolean) ShouldContinue(String, String, Boolean, Boolean) ShouldContinue(String, String, Boolean, Boolean)

Confirm an operation or grouping of operations with the user. This differs from ShouldProcess in that it is not affected by preference settings or command-line parameters, it always does the query. This variant offers Yes, No, YesToAll and NoToAll.

(Inherited from Cmdlet)
ShouldContinue(String, String, Boolean, Boolean, Boolean) ShouldContinue(String, String, Boolean, Boolean, Boolean) ShouldContinue(String, String, Boolean, Boolean, Boolean) ShouldContinue(String, String, Boolean, Boolean, Boolean)

Confirm an operation or grouping of operations with the user. This differs from ShouldProcess in that it is not affected by preference settings or command-line parameters, it always does the query. This variant offers Yes, No, YesToAll and NoToAll.

(Inherited from Cmdlet)
ShouldProcess(String) ShouldProcess(String) ShouldProcess(String) ShouldProcess(String)

Confirm the operation with the user. Cmdlets which make changes (e.g. delete files, stop services etc.) should call ShouldProcess to give the user the opportunity to confirm that the operation should actually be performed.

(Inherited from Cmdlet)
ShouldProcess(String, String) ShouldProcess(String, String) ShouldProcess(String, String) ShouldProcess(String, String)

Confirm the operation with the user. Cmdlets which make changes (e.g. delete files, stop services etc.) should call ShouldProcess to give the user the opportunity to confirm that the operation should actually be performed.

This variant allows the caller to specify text for both the target resource and the action.

(Inherited from Cmdlet)
ShouldProcess(String, String, String) ShouldProcess(String, String, String) ShouldProcess(String, String, String) ShouldProcess(String, String, String)

Confirm the operation with the user. Cmdlets which make changes (e.g. delete files, stop services etc.) should call ShouldProcess to give the user the opportunity to confirm that the operation should actually be performed.

This variant allows the caller to specify the complete text describing the operation, rather than just the name and action.

(Inherited from Cmdlet)
ShouldProcess(String, String, String, ShouldProcessReason) ShouldProcess(String, String, String, ShouldProcessReason) ShouldProcess(String, String, String, ShouldProcessReason) ShouldProcess(String, String, String, ShouldProcessReason)

Confirm the operation with the user. Cmdlets which make changes (e.g. delete files, stop services etc.) should call ShouldProcess to give the user the opportunity to confirm that the operation should actually be performed.

This variant allows the caller to specify the complete text describing the operation, rather than just the name and action.

(Inherited from Cmdlet)
StopProcessing() StopProcessing() StopProcessing() StopProcessing()

When overridden in the derived class, interrupts currently running code within the command. It should interrupt BeginProcessing, ProcessRecord, and EndProcessing. Default implementation in the base class just returns.
