[jira] [Created] (SEDONA-458) The docs should have examples for UDF

Jia Yu created SEDONA-458:
-----------------------------

             Summary: The docs should have examples for UDF
                 Key: SEDONA-458
                 URL: https://issues.apache.org/jira/browse/SEDONA-458
             Project: Apache Sedona
          Issue Type: Task
            Reporter: Jia Yu


We should add Scala/Java/Python UDF examples for Sedona. The example should show how users implement a UDF to access the geometry type object in Apache Sedona DataFrame.

 

The UDF examples should include examples as follows. Each example should have Scala, Java, and Python snippet.

 

1.

Input: geometry

Output: geometry

 

2.

Input: geometry

Output: other primitive type

 

3. 

Input: geometry, other primitive type

Output: geometry

 

4.

Input: geometry, other primitive type

Output: geometry, other primitive type (this can be done via struct type)
