Dan Smith created GEODE-1577: -------------------------------- Summary: Unhelpful generic types on Execution.execute Key: GEODE-1577 URL: https://issues.apache.org/jira/browse/GEODE-1577 Project: Geode Issue Type: Bug Components: functions Reporter: Dan Smith
The execute methods of the function service Execution class returns a ResultCollector with wildcards for the type. {code} public ResultCollector<?, ?> execute( Function function) throws FunctionException; {code} Wildcards are supposed to be used in APIs where the type doesn't matter, for example counting the elements in a list. By returning a ResultCollector with wildcards, we're essentially forcing the user to cast the result collector. At a minimum they should be able to pick the type of result collector {code} public <T,S> ResultCollector<T, S> execute( Function function) throws FunctionException; {code} But maybe it would make more sense to parameterize Execution itself. Then the compiler could ensure that the types used by withCollector and the types used by execute match. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
