Derived Property Handler

ilog.rules.studio.model.derivedPropertyHandlers

JRules 6.0

Allows plug-ins to specify handlers that dynamically compute a value for extractable properties. An extractable property handler is called during IRL code generation, when the value of the property need to be retrieved by the rule engine.

id - String key identifying the handler. This ID is used to associate the handler with the properties that should be considered. It can either be the qualified name of the property, or a key used in property annotations of the rule model extension files.
handlerClass - The fully-qualified name of the Java class that implements the ilog.rules.commonbrm.model.IlrExtractablePropertyHandler interface. It must be a Java class with a public default constructor.

<extension point=
"ilog.rules.studio.model.extractablePropertyHandlers"

      <extractablePropertyHandler 
            handlerClass=
"sample.StatusHandler"

            id=
"model.rule.BusinessRule.active"
/>
      <extractablePropertyHandler
            handlerClass=
"sample.DateHandler"

            id=
"dateExtractableHandlerID"
/>
</extension>

See ilog.rules.commonbrm.model.IlrExtractablePropertyHandler.

The ID of each extractable property handler extension can be either the fully-qualified name of the property that is targeted, or a key that is associated to the property in rule model extension files (*.brmx files).
