Class ObjectFactory

java.lang.Object
  org.drools.base.evaluators.ObjectFactory

All Implemented Interfaces:

Serializable, EvaluatorFactory

---

public class ObjectFactory
extends Object
implements EvaluatorFactory

This is the misc "bucket" evaluator factory for objects. It is fairly limited in operations, and what operations are available are dependent on the exact type. This supports "<" and ">" etc by requiring objects to implement the comparable interface. Of course, literals will not work with comparator, as it has no way of converting from literal to the appropriate type.
