Type Members

1.  case class Binding(name: String, value: Value) extends Product with Serializable
2.  case class Component[F[_]](mapping: Mapping[F], join: (Cursor, Query) => Result[Query], child: Query) extends Query with Product with Serializable

   Identifies a component boundary.

   Identifies a component boundary. join is applied to the current cursor and child yielding a continuation query which will be evaluated by the interpreter identified by componentId.

3.  case class Count(name: String, child: Query) extends Query with Product with Serializable

   Computes the number of top-level elements of child as field name

4.  case class Defer(join: (Cursor, Query) => Result[Query], child: Query, rootTpe: Type) extends Query with Product with Serializable

   A deferred query.

   A deferred query. join is applied to the current cursor and child yielding a continuation query which will be evaluated by the current interpreter in its next stage.

5.  case class Environment(env: Env, child: Query) extends Query with Product with Serializable

   Add env to the environment for the continuation child

6.  case class Filter(pred: Predicate, child: Query) extends Query with Product with Serializable

   Retains only elements satisfying pred and continues with child

    Select field name given arguments args and continue with child

17.  case class Skip(sense: Boolean, cond: Value, child: Query) extends Query with Product with Serializable

    Skips/includes the continuation child depending on the value of cond

18.  case class Unique(child: Query) extends Query with Product with Serializable

    Continues with single-element-list-producing child and yields the single element

19.  case class UntypedNarrow(tpnme: String, child: Query) extends Query with Product with Serializable

    Untyped precursor of Narrow.
