----------------------------------
Summary: Use ProjectionConsumer in FieldAccessVisitor.
Key: BEAM-13431
URL: https://issues.apache.org/jira/browse/BEAM-13431
Project: Beam
Issue Type: Improvement
Components: sdk-java-core
Reporter: Kyle Weaver
I created an interface for ProjectionConsumer and then neglected to use it.
Using ProjectionConsumer rather than handling transforms case-by-case will make
FieldAccessVisitor easier to extend.
Changing this would require ParDo.MultiOutput to implement ProjectionConsumer.
