Juan José Ramos Cassella updated GEODE-7195:
--------------------------------------------
Labels: GeodeCommons (was: )
> Add BeforeAggregates Callback in QueryObserver
> ----------------------------------------------
>
> Key: GEODE-7195
> URL: https://issues.apache.org/jira/browse/GEODE-7195
> Project: Geode
> Issue Type: Improvement
> Components: querying
> Reporter: Juan José Ramos Cassella
> Priority: Major
> Labels: GeodeCommons
>
> The interface is used by testing/debugging code to be notified of query
> events. We should add a new callback to be invoked *after* executing the
> query criteria but *before* applying the aggregate functions and group by
> clauses:
> {code:title=CompiledGroupBySelect.java|borderStyle=solid}
> @Override
> public SelectResults evaluate(ExecutionContext context) throws
> FunctionDomainException, TypeMismatchException, NameResolutionException,
> QueryInvocationTargetException {
> SelectResults sr = super.evaluate(context);
> // Invoke Listener Here!
> return this.applyAggregateAndGroupBy(sr, context);
> }
> {code}
