   an arbitrary key type for a given persistent type P

2. sealed case class ConditionalQuery[P <: Persistent](lhs: Query[P], op: LogicalOp, rhs: Query[P]) extends Query[P] with Product with Serializable

   

   a conditional query.

3. trait DerivedPType[P <: Persistent, Poly >: P <: Persistent] extends PType[P]

   

   one of the derived types in a family of persistent types.

   one of the derived types in a family of persistent types. mix this in to youe persistent type when it represents a concrete subtype of a PolyPType.

4. sealed case class EqualityQuery[P <: Persistent, A](prop: Prop[_ >: P <: Persistent, A], op: EqualityOp, value: A) extends Query[P] with Product with Serializable

   an equality query. compares a property to a value with an eq or an neq operator.

   prop

   the property to compare

   op

   the eq or neq operator

   value

   the value to compare

5. abstract class EventType[E <: Event] extends PType[E]

   

   a type class for events

6. case class Index[P <: Persistent] extends Product with Serializable

   

   an index for a persistent type

   an index for a persistent type

   P

   the persistent type

7. case class Key[P <: Persistent, V <: KeyVal[P, V]] extends Product with Serializable

   

   a natural key for this persistent type.

   a natural key for this persistent type. wraps a property that, given specific a property value, will match the corresponding member of no more than one persistent object.

   P

   the persistent type

   V

   the key value type

8. sealed case class OrderingQuery[P <: Persistent, A](prop: Prop[_ >: P <: Persistent, A], op: OrderingOp, value: A) extends Query[P] with Product with Serializable

11. trait PolyPType[P <: Persistent] extends PType[P]

    

    the base type for a family of persistent types.

    the base type for a family of persistent types. mix this in to your persistent type when it represents an abstract persistent type with concrete subtypes.

12. case class Prop[P <: Persistent, A] extends Product with Serializable

    

    a property for this persistent type.

    a property for this persistent type. properties map to underlying members within the [Persistent persistent object], at any depth.

    properties can be used to define keys and indexes, as well as for building queries. a property can descend from the root into child entities at any depth.

    at present, a property cannot pass through any collections or terminate with a polymorphic embeddable. violations will cause an exception to be thrown on Subdomain construction.
