Constructors

PSActivity()

Constructor for the PSActivity class.

Fields

PSBookmarkPrefix

The bookmark prefix for Powershell activities.

PSPersistBookmarkPrefix

The bookmark prefix for Powershell persist activities.

PSSuspendBookmarkPrefix

The bookmark prefix for Powershell suspend activities.

Properties

AppendOutput

Determines whether to append output to Result.

(Inherited from PipelineEnabledActivity)
CanInduceIdle

In order for an activity to go idle, 'CanInduceIdle' should be true.

Debug

Determines whether to emit debug output of the activity.

DefiningModule

If an activity needs to load a module before it can execute, override this member to return the name of that module.

ErrorAction

Determines how errors should be handled by the activity.

InformationAction

Determines how information records should be handled by the activity.

Input

The Input stream for the activity.

(Inherited from PipelineEnabledActivity)
MergeErrorToOutput

Determines whether to merge error data to the output stream

ParameterDefaults

Provides access to the parameter defaults dictionary

PSActionRetryCount

Defines the number of retries that the activity will make when it encounters an error during execution of its action. The default is to not retry.

PSActionRetryIntervalSec

Defines the delay, in seconds, between action retry attempts. The default is one second.

PSActionRunningTimeoutSec

Defines the maximum amount of time, in seconds, that this activity may run. The default is unlimited.

PSCommandName

Gets the fully qualified name of the command invoked by this activity.

PSDebug

The Debug stream / collection for the activity.

PSDefiningModule

Returns the module defining the command called by this activity. It may be null.

PSDisableSerialization

Forces the activity to return non-serialized objects. Resulting objects have functional methods and properties (as opposed to serialized versions of them), but will not survive persistence when the Workflow crashes or is persisted.

PSError

The Error stream / collection for the activity.

PSInformation

The Information stream / collection for the activity.

PSPersist

Forces the activity to not call the persist functionality, which will be responsible for persisting the workflow state onto the disk.

PSProgress

The Progress stream / collection for the activity.

PSProgressMessage

In addition to the display name PSProgress Message will provide the way to append the additional information into the activity progress message like branch name or iteration number in case of parallel foreach.

PSRequiredModules

This the list of module names (or paths) that are required to run this Activity successfully. The default is null.

PSVerbose

The Verbose stream / collection for the activity.

PSWarning

The Warning stream / collection for the activity.

Result

The output stream from the activity

(Inherited from PipelineEnabledActivity)
Tracer

Tracer initialization.

UpdatePreferenceVariable

Indicates if preference variables need to be updated

UseDefaultInput

Determines whether to connect the input stream for this activity.

(Inherited from PipelineEnabledActivity)
Verbose

Determines whether to emit verbose output of the activity.

WarningAction

Determines how warnings should be handled by the activity.

Methods

ActivityEndPersistence(NativeActivityContext)

The method is override-able by the drived classes in case they would like to implement different logic at the end of persistence. The default behavior would be to schedule the 'Persist' activity if the PSPersist flag is true or Host is asking for it.

CacheMetadata(NativeActivityMetadata)

Retrieves the stream and ubiquitous parameter information from the hosting application. These must be passed in as "Streams" and "UbiquitousParameters", respectively.

Cancel(NativeActivityContext)

Cancel the running activity

Execute(NativeActivityContext)

Begins the execution of the activity.

GetActivityArguments()

Retrievs all of the default arguments from the type and its parents.

GetImplementation(NativeActivityContext)

Overload this method to implement any command-type specific preparations. If this command needs any workflow-specific information during its PrepareSession call, it should be stored in ActivityImplementationContext.WorkflowContext.

GetPowerShell(NativeActivityContext)

The method for derived activities to return a configured instance of System.Management.Automation.PowerShell. The implementor should have added all of the commands and parameters required to launch their command through the standard AddCommand() and AddParameter() methods. Derived activites should not manage the Runspace property directly, as the PSActivity class configures the runspace afterward to enable remote connections.

GetRunInProc(ActivityContext)

Determine if this activity should be run in or out of process when run locally/

PrepareSession(ActivityImplementationContext)

The method for derived activities to customize the runspace of a System.Management.Automation.PowerShell instance that the runtime has prepared for them. If the command needs any workflow-specific information during this PrepareSession call, it should be stored in ActivityImplementationContext.WorkflowContext during the GetCommand preparation phase.

UpdateImplementationContextForLocalExecution(ActivityImplementationContext, ActivityContext)

Updates the ImplementationContext returned from GetPowerShell() to support local execution against the host's runspace pool.

WriteProgressRecord(NativeActivityContext, PSDataCollection<ProgressRecord>, String, ProgressRecordType)

Write a progress record fo the current activity
