Rules

ACMA provides a base set of rules that can be used on attribute constructors, constructor groups, events.
The rules are broken up into two types.

Event-based rules

Event-based are very fast and efficient rules that look at the in-memory changes on an object. They are the lowest-cost rules to evaluate, and as such ACMA will evaluate event-based rules within a group first.

Comparison-based rules

Comparison-based rules compare values on an object in the database against the parameters defined in the rule.

Rule groups

Rule groups are used to do more complex evaluations of an object. Rule groups can contain any number of rules, as well as child rule groups. They allow a conditional evaluation to take place, specifying that all, any, one, or none of their child rules and rule groups must pass evaluation for the group itself to pass.

Rule debugging

At times, you may need to debug your rules to find out why a constructor or event isn't triggering. By default, ACMA doesn't log the details of rules comparisons, but debugging can be turned on by a registry setting. Please note that this setting will generate very large log files, so ensure you have plenty of disk space, and be sure to turn it back off when you have completed your investigation.

To turn on advanced rule debugging, create or set the value of the following registry value as shown below
HKEY_LOCAL_MACHINE\Software\Lithnet\ACMA
Key Name: Rule Debugging
Type: DWORD
Value: 1


To turn off advanced rule debugging, delete or set the value of the following registry value as shown below
HKEY_LOCAL_MACHINE\Software\Lithnet\ACMA
Value Name: Rule Debugging
Type: DWORD
Value: 0
