Control Flow Module

The Control Flow activities module provides activities for controlling flow of execution within your project.

Note that while activities such as the Parallel and Sequence schedule multiple child activities for execution simultaneously, only a single thread is used for a workflow. Each child activity of these activities executes sequentially and successive activities do not execute until previous activities either complete or go idle. As a result, these activities are most useful for applications in which several potentially blocking activities must execute in an interleaved fashion. If none of the child activities of these activities go idle, a Parallel activity executes just like a Sequence activity.

Activities

The table below shows the activities in the Control Flow activities module and their key properties.

Activity	Description
If	Condition Activity which models an If-Then-Else action
Parallel	Executes all sequenced set of activities simultaneously and asynchronously.
Sequence	Executes a set activities according to a single, defined ordering.
While	Executes a set of workflow elements while a condition evaluates to true.
Switch	Executes a set of activities depending on a value (can be a datafield read in a source, a variable, a parameter value)
Start	Optional activity to set the starting point of the workflow. If not used, the starting point is the first activity of the workflow.
OnDemand	Acts as a container to hold OnDemand activities so that they are easily accessible at design time. At run time, each activity is executed directly
Redirect	Redirects execution to a specific workflow activity.
