Cast<T>	Set of utilities for casting rows between schemas.
Cast.CompatibilityError	Describes compatibility errors during casting.
Cast.Narrowing	Narrowing changes type without guarantee to preserve data.
Cast.Widening	Widening changes to type that can represent any possible value of the original type.
CoGroup	A transform that performs equijoins across multiple schema PCollections.
CoGroup.By	Defines the set of fields to extract for the join key, as well as other per-input join options.
CoGroup.ExpandCrossProduct	A PTransform that calculates the cross-product join.

Group.CombineGlobally<InputT,OutputT>	a PTransform that does a global combine using a provider Combine.CombineFn.
Group.Global<InputT>	A PTransform for doing global aggregations on schema PCollections.
Join	A transform that performs equijoins across two schema PCollections.
Join.FieldsEqual	Predicate object to specify fields to compare when doing an equi-join.
Join.FieldsEqual.Impl	Implementation class for FieldsEqual.
Join.Impl<LhsT,RhsT>	Implementation class .
RenameFields	A transform for renaming fields inside an existing schema.
RenameFields.Inner<T>	The class implementing the actual PTransform.
Select<T>	A PTransform for selecting a subset of fields from a schema type.
Unnest	A PTransform to unnest nested rows.
Unnest.Inner<T>	A PTransform that unnests nested row.
