Subject [jira] [Created] (GEODE-393) FunctionContext should provide a Cache
Date Fri, 09 Oct 2015 20:47:06 GMT

-------------------------------

             Summary: FunctionContext should provide a Cache
                 Key: GEODE-393
                 URL: https://issues.apache.org/jira/browse/GEODE-393
             Project: Geode
          Issue Type: Improvement
          Components: functions
            Reporter: Dan Smith


FunctionContext has methods to get the arguments to the function and the result sender, but
there is no way to get the Cache or DistributedSystem.

This means pretty much any function will need to statically look up the cache using CacheFactory.getAnyInstance().
While that works, it makes it impossible to write unit tests for functions by passing in a
mock cache.

Note that onRegion functions are provided a RegionFunctionContext, which does provide these
functions with a means to look up the cache, but not all functions are applied to a region.
