object ExtractPythonUDFs extends Rule[SparkPlan] with PredicateHelper

Extracts PythonUDFs from operators, rewriting the query plan so that the UDF can be evaluated alone in a batch.

Only extracts the PythonUDFs that could be evaluated in Python (the single child is PythonUDFs or all the children could be evaluated in JVM).

This has the limitation that the input to the Python UDF is not allowed include attributes from multiple child operators.
