[jira] [Created] (BEAM-1159) DoFnSignature should have info on the fn's side inputs and outputs

Eugene Kirpichov created BEAM-1159:
--------------------------------------

             Summary: DoFnSignature should have info on the fn's side inputs and outputs
                 Key: BEAM-1159
                 URL: https://issues.apache.org/jira/browse/BEAM-1159
             Project: Beam
          Issue Type: Improvement
            Reporter: Eugene Kirpichov


This is logically part of the fn itself, rather than its enclosing transform.

Example where this would have been important: signature.processElement().observesWindow() should return true for a DoFn that has any side inputs, since side inputs are windowed. See BEAM-1149.
