About Collection rules
|
Use a collection to model business logic and implement common rule engine patterns. Collections define an ordered sequence of rules, the conditions under which they execute, and post-processing steps known as response actions. The business-friendly options on this form help you to quickly develop flexible solutions that are easily understood by various audiences.
Note: The original implementation of the Collection form is deprecated. While you cannot create any new instance of the original form, legacy instances in your application remain functional.
Collections can be called by a Collect instruction in an activity or a step in another collection rule. Collections can also be associated with specifications.
Use the Application Explorer to access collections that apply to a specific class in your application. Use the Records Explorer to list all collections available to you.
Enable the Declare Collections setting to view collections output in a Tracer session.
Click Actions > View Java to view the generated Java of a rule. You can use the Java code to debug your application or to examine how rules are implemented.
Collection rules are instances of the Rule-Declare-Collection class. They are part of the Decision category.
