If checked, this field allows more than one rule with the same name and class to be present in the system. Other rules, such as Rule-Method, do not have the Use class-based inheritance box checked. If Find by Name Pattern First? If the rule is not present in that class, Process Commander will search other classes, based on specific procedures. It is possible for Rules to have this box checked and not have the Use classbased inheritance to arrive at the correct rule to execute box checked, as they operate independently.
Popular in Areas Of Computer Science. Allow multiple versions with the same key values Rule Resolution This is the most important choice for Rule Resolution, as it enables or disables the functionality. It may contain trade secrets and proprietary information.
When classes are defined, different features are enabled which affect inheritance and rule resolution. They are included as an exercise, to show the effect of turning off pattern inheritance, which is not recommended. Therefore, if this box is checked, Rule Resolution will be used to open instances of this class.
For example, Declarative rules may not use Circumstances, and this feature is missing from those rules. This document is current as of the date of publication only. This document is not an in-depth exploration of Rule Resolution itself, but an explanation of how the concept of class inheritance is used in a Process Commander system to facilitate Rule Resolution. If the Allow multiple versions with the same key values box is not checked, then this choice is not valid.
Other brand or product names are trademarks of their respective holders. However, if Find by Name Pattern First?
There are several paths that rule resolution for this Activity could take, depending upon what inheritance options are chosen. Find by name first Pattern determines pattern inheritance. For almost every class, Pattern inheritance should remain enabled checked. Additional Inheritance Examples These examples are less likely to be seen in Process Commander applications.
