Detailed Description

Represents types and information to determine the size of the columns as input/output of a User Defined Function/Transform.

This class is used to exchange size and precision information between Vertica and the user defined function/transform function. Vertica provides the user code with size/precision information about the particular data types that it has been called with, and expects the user code to provide size/precision information about what it will return.
