Wesley Tanaka created BEAM-3035:

             Summary: Extract ReifyTimestampsAndWindows from GatherAllPanes
                 Key: BEAM-3035
                 URL: https://issues.apache.org/jira/browse/BEAM-3035
             Project: Beam
          Issue Type: New Feature
          Components: sdk-java-core
    Affects Versions: 2.1.0
            Reporter: Wesley Tanaka
            Assignee: Kenneth Knowles
            Priority: Minor


The {{ReifyTimestampsAndWindowsFn}} in {{GatherAllPanes}} looks useful for giving {{MapElements}},  {{Filter}}, etc access to window and pane information.

This JIRA represents the proposal to extract a subset of the {{GatherAllPanes}} functionality into a new class {{ReifyTimestampsAndWindows}}, next to {{ReifyTimestamps}} which does similar functionality but with {{TimestampedValue}}

{{GatherAllPanes}} would then rely on the newly extracted public {{PTransform}} for its previous functionality.
