Zheng Shao commented on HIVE-45:
--------------------------------
I plan to add a new package: ql.udf.template for this.
CASE and IF will be implemented as a subclass of this UDFTemplate.
This will also allow functions with dynamic number of parameters.
> Hive: UDFTemplate and support of complex object

>
> We should allow users to define UDF template (in the sense of c++ template
> that can take args of different types), and let UDF take complex objects.
> This should be pretty simple given that we have the ObjectInspector which can
> navigate through the internal structure of the object.
