Rafal Glowinski created GEODE-782:
-------------------------------------
Summary: RegionFunctionContext.getFilter() should never return null
Key: GEODE-782
URL: https://issues.apache.org/jira/browse/GEODE-782
Project: Geode
Issue Type: Wish
Reporter: Rafal Glowinski
Currently, RegionFunctionContext.getFilter() returns null reference if function
has been called without providing any keys to filter.
I think that it would be much better to return Collections.EMPTY_SET instead so
that we should not check filter for null reference whenever we write custom
functions.
I would be happy to implement it myself to get started with Geode OSS.
