Currently in draft. Requires technical input from Eleanor and context input from Skevi.

This page is for application designers who need to configure when a specific operation will change data in the stream.

Action Concepts

A stream has a set of  Stream Item Actions (SIA). These represent the smallest, specific operation that can happen to the data in the stream.

You can configure one action to run on the data in different streams. This is because the action contains:

  • a list of stream item actions (SIA) from different streams. The action can potentially run any of these SIA.
  • with each SIA, is the rule that specifies the conditions for that SIA to be run.

To use a SIA in an action:

  1. Open the Action properties.
  2. In the toolbar of the Stream Item Action Rules section:
    • either click  Add New  to create a new SIA rule. 
    • or click  Stream Item Action (SIA) to open a repository list of streams.
      Expand the branch for the stream, then drag its SIA into the action properties → Stream Item Action Rules grid.
      Double-click on a SIA rule in the grid to open its properties. 

Properties

If you add or open a SIA rule, PhixFlow opens its properties tab. Use the following properties to configure the conditions or rules under which the SIA will run. 

This properties tab is not available from the repository. It only opens from the Action properties.

For information about the properties toolbar, and about the sections Parent Details, Analysis Models, Description and Audit Summary, see Common Properties.  We recommend you always add a Description that explains the purpose of the item you are creating. 

For a full list of all the PhixFlow property tabs and windows, see Properties, Windows, Menus and Toolbars.

Basic Settings

FieldDescription
Stream Item Action

The name of the stream item action (SIA)

To add or change the name do one of the following:

  • select a SIA name from the drop-down list of all SIAs in the repository.
  • click  Add New to create a new one; see Stream Item Actions (SIA)
  • click  Stream Item Action (SIA) to open the repository Streams branch to find a SIA and drag it in. This makes it easier to find a SIA for a specific stream.
Stop if TrueIf the following expression is true, stop the SIA from running.??
Expression

Enter an expression.

Details??

Order

Specify the order in which this SIA is listed in the action properties → Stream Item Action Rules grid.

Order is important because, when evaluating the SIA rule expression, PhixFlow starts with the first SIA in the list. It will run the first SIA that it finds for which the expression evaluates to true. Subsequent SIA will not be evaluated or run.
