Rate modifiers

You can define rating modifiers on custom lines of business. The Golf Cart line has rating modifiers for both the policy line and the golf cart. For example, rating modifiers can modify the premium rate on the line with a multi-policy discount. Or rating modifiers can modify the premium rate on the golf cart with a discount for good driving record. You can control the availability of rating modifiers by using availability lookup tables.

Delegates actively connect the modifiable to its modifier. A delegate establishes the interface from one object to another. The ModifiableAdapter links the Modifiable to the Modifier.

The Golf Cart line has two modifiable objects: GolfCartLine and GOCart. Each modifiable object has a modifier, GOModifier and GOCartModifier, respectively. Each modifier has modifier methods. Each modifiable object has a modifiable adapter that connects the modifiable object to its modifier.

The following illustrations shows GolfCartLine and its modifier objects:

The following illustrations shows GOCart and its modifier objects:

Defining modifiers is similar to defining coverages, with a few differences. Instead of defining a CoverableAdapter, you define a ModifiableAdapter for each modifiable object. Instead of defining a CoverageAdapter, you define a ModifierAdapter for each modifier. In addition, you must define a MatchableEffDated delegate on the modifier. This delegate handles out-of-sequence events and preemption.
