public class ArdenClause
extends java.lang.Object
```
Arden Clauses are represented by ArdenClause classes. Clauses can be constructed from concepts, rules, or other clauses. They also expose aggregate and predicate methods such as earliest(), latest(), max(), and greaterThan(n). Every method returns another ArdenClause. The Arden Clauses do not actually fetch data or return values; rather, they represent a semantic hierarchy needed to resolve a particular Arden Value. The criteria are abstracted so an Arden Clause can be passed down to the database layer and, ideally, be translated to SQL or similar language.
