Control Flow Module

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

Control Flow Activities

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
FlowDecision	FlowChart Activity with Yes/No branches based on a Condition
If	Condition Activity which models an If-Then-Else action
Parallel	Executes all child activities simultaneously and asynchronously.
Sequence	Executes a set of child activities according to a single, defined ordering.
While	Executes a contained set of workflow elements while a condition evaluates to true.
Switch	Executes a contained 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 staring point is the first activity of the workflow.
Redirect	Redirect the flow to a specific activity of the workflow (optionnally based on a condition)
