[jira] [Created] (BEAM-6150) Provide alternatives to SerializableFunction and SimpleFunction that may declare exceptions

Jeff Klukas created BEAM-6150:
---------------------------------

             Summary: Provide alternatives to SerializableFunction and SimpleFunction that may declare exceptions
                 Key: BEAM-6150
                 URL: https://issues.apache.org/jira/browse/BEAM-6150
             Project: Beam
          Issue Type: Improvement
          Components: sdk-java-core
            Reporter: Jeff Klukas
            Assignee: Jeff Klukas


Contextful.Fn allows subclasses to declare checked exceptions, but neither SerializableFunction nor SimpleFunction do. We want to add a new entry in each of those hierarchies where checked exceptions are allowed. We can then change existing method signatures to accept the new superinterfaces in contexts where allowing user code to throw checked exceptions is acceptable, such as in ProcessElement methods.

Discussed on the dev mailing list:
