UDTRegistration

object UDTRegistration extends Serializable with Logging

This object keeps the mappings between user classes and their User Defined Types (UDTs). Previously we use the annotation SQLUserDefinedType to register UDTs for user classes. However, by doing this, we add SparkSQL dependency on user classes. This object provides alternative approach to register UDTs for user classes.
