TypeRegistry ------------- As part of adding new types, the TypeRegistry is now a class rather than a static object. This shows up in the Database class as db.types. A generic instance DefaultTypeRegistry uses hardcoded settings. Eventually, we'll be able to have a type registry that talks to the metadata repo. Type -> TUser + BaseType ------------------------- The majority of the code in this codebase is not aware of / set up to work with Mimir's user-defined types (TUser). That's something that's going to need to change over time, but due to the above fix, it's clear that we need to make the distinction more crisp. Now, there's a new (sealed abstract) subclass of Type called BaseType that is now the parent of all types except TUser. - The Type object is now the BaseType object and has nothing to do with TUser - TypeRegistry has been moved (see above) - Code without access to an instance of Database has been rewritten to use BaseType - Code with access to an instance of Database is uses the new TypeRegistry - To get the BaseType of a Type, use db.types.rootType OperatorTransforms -> Class ---------------------------- OperatorTransforms (both GProM and Spark) used a global Database instance. Database is enough of a hack... These have been rewritten to be classes with canonical instances accessible as db.gpromTranslator / db.sparkTranslator. Spark's OperatorTransforms retains several general methods in the global object.
