---------------------------------
Summary: Count should return a more specific type than PTransform
Key: BEAM-2501
URL: https://issues.apache.org/jira/browse/BEAM-2501
Project: Beam
Issue Type: Improvement
Components: sdk-java-core
Reporter: Thomas Groh
As {{Count.globally()}} and other static factory methods return objects of type
{{PTransform}}, there is no way to communicate to the underlying {{Combine}}
that we wish to have no default values, or to read the count as a
{{SingletonView}} via the combiner.
