> GenericUDF class is the latest and recommended base class for any UDFs.
> This JIRA is to change the current UDFDate* classes extended from GenericUDF.
> The general benefit of GenericUDF is described in comments as
> "* The GenericUDF are superior to normal UDFs in the following ways: 1. It can
> accept arguments of complex types, and return complex types. 2. It can accept
> variable length of arguments. 3. It can accept an infinite number of function
> signature - for example, it's easy to write a GenericUDF that accepts
> array<int>, array<array<int>> and so on (arbitrary levels of nesting). 4. It
> can do short-circuit evaluations using DeferedObject."
