Query Model Extension

Identifier:

Since:

Description:

Allows plug-ins to extend the rule model on which queries operate.

Properties added through the extension model are automatically available in the query vocabulary. However, in order to add new query predicates, you need to use this extension point. See the documentation sections:

• ILOG JRules User Guide > Customizing JRules > Tasks > Defining Common Model Extensions for Rule Studio and Rule Team Server > Extending the Queries
• ILOG JRules User Guide > Customizing JRules > Tasks > Customizing Rule Studio > Integrating Query Extensions into Rule Studio
