IRule Interface

Provides access to members that return information about rules.

Description

The IRuleinterface is used to configure and access rules that object classes must adhere to be successfully validated. There are four types of rules that can be created: attribute rules, connectivity rules (edge and junction), relationship rules, and topology rules.

When To Use

The IRule interface is used to get and set the common properties for all rule types. For example, you can set or get the category, help string, and ID for the rule and you can also get an esriRuleType value, representing the rule's type. You would use IRule when you want to create rules for a particular object class so that it can be validated.
