sealed abstract class Type extends Product with Serializable

Type is an intermediate form from which record/variant objects or type aliases are generated from.

You might be wondering, why so many data structures for types We've got Core.Type and Package.ParamType, now why do we need yet another?

The reason we have chosen to use the Core.Type in the typeDecls field of com.daml.core.Package.PackageInterface is because other programs besides the DAML Scala code generator inspect this data structure. (e.g. Integration Adapter as of 07 Sep 2017).

The Package.ParamType structure represents all types that are valid parameters in app-side contract templates.

The Type structure defined in this module defines all types that can validly have a Scala data structure generated from them. This is slightly more sophisticated data structure than Package.ParamType since it contains type variables which, when present, are used to generate polymorphic Scala data structures.

Only a subset of Core.Type values can be translated to Type values. The method com.daml.core.Package#validTypeSynonymRHS returns 

true

when a Core.Type value can be translated.

    Handle the possible Types without missing one or casting.

    Handle the possible Types without missing one or casting. Meant to be used from Java.

    Note

    Normally Type's recursive occurrences would be replaced with Z, but we have not done that for closer analogy to pattern matching.

    Fold over the TypeConNameOrPrimTypes therein.
