Is Spark 2.3+ support UDT?

I was going through this ticket https://issues.apache.org/jira/browse/SPARK-7768?jql=text%20~%20%22public%20udt%22 and could not understand that if spark support UDT in  2.3+ version in any language (scala, python , java, R) ?

I have class something like this

Class Test

{        string name;        int age; }

 

And My UDF method is:

public Test UDFMethod(string name, int age)

{           Test ob = new Test();           ob.name = name;           ob.age = age; }

Sample Spark query-   `Select *, UDFMethod(name, age) From SomeTable;`

Now UDFMethod(name, age) will return Class Test object. So will this work in Spark SQL after using SQLUserDefinedType tag and extending UserDefinedType class.
