— Standard activities — Extension points
|
|
The activity names listed here, known as extension points, are by design implemented at the @baseclass, Assign- or Work- level and have an empty Steps tab. These are sometimes informally known as placeholders or callbacks; they allow your application to extend the processing provided by a standard rules that are marked as final.
In your application, you can override these stubs with an activity that applies to a work type (or work pool) to implement desired processing at the events indicated. Typically, the standard calling activities noted below are marked as final, and so they cannot be overridden.
In most cases, place the overriding activity in a more specific (lower level) Applies To class.
Extension points marked with a dot (
) are part
of the Process Engine API. See Standard activities —
Process Engine API.
Extension points in
the Assign- class
As a best practice, override these activities using an Applies To key part that is a cover work type in your application. MARIK 07/06/05
Name |
Purpose |
| Assign-. NewDefaults
|
Called from Work-.NewAssign and Work-.NewAssignBasket on the assignment. Allows the developer to customize or extend the steps that are performed when a new assignment is created. |
| Assign-Service. HandleInterrupt
|
For an asynchronous service call that is interrupted by a ticket, or by a service level event (such as from the ResumeFlow service level). Can send a message to the called external system to indicate that a flow has advanced beyond the connector call, for example because a ticket was activated. Called by the RemoveAssignmentByTicket and Assign-.CompleteAssignment activities. |
Extension points in
the Work- class
As a best practice, override these activities using an Applies To key part that is a work type in your application. MARIK 07/06/05
Name |
Purpose |
|
Work-
|
May be called by Work-.AddCoveredWork. Override to customize or extend the steps that are performed during post-processing of the addition of a covered work object using a flow action. Called by the post-processing activity of the Work-.AddCovered flow action. |

of the AddCovered flow action. Override to
customize or extend the steps performed before adding a
covered object. |
| Work- .CloseDefaults

| Work- PreClose |
Called by the Work-.CloseWorkItem activity. Allows developers to control what appears when a user closes a work object form, such as by clicking the close box. By default, the next display is the user's worklist, but your application can call the GetNextWork activity or present a different display. MARIK 3/17/06 SP5SR-1240 |

this activity with an activity where the Applies
To key part is a rule type. Called by standard
activities named Rule-ZZZZ.CheckForWarnings,
where Rule-ZZZZ is a rule type. Call the standard function
addWarning(), and override the standard decision
