getPythonFunction

org.apache.flink.table.functions.python.PythonFunction getPythonFunction(String moduleName,
                                                                         String objectName)

Returns PythonFunction according to moduleName and objectName.

参数:

moduleName - The module name of the Python UDF.

objectName - The function name / class name of the Python UDF.

返回:

The PythonFunction object which represents the Python UDF.
