    Component/s: functions

> RegionFunctionContext.getFilter() should never return null

>                 Key: GEODE-782
>                 URL: https://issues.apache.org/jira/browse/GEODE-782
>             Project: Geode
>          Issue Type: Wish
>          Components: functions
>            Reporter: Rafal Glowinski
>            Priority: Minor
>
> 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 know that current behaviour should remain unchanged due to backward compatibility, but maybe current getFilter() method could be made @Deprecated and new one introduced?
> I would be happy to implement it myself to get started with Geode OSS.
