Andy Jefferson commented on JDO-736:
------------------------------------
One problem with having
setParameters(Map namedParamMap);
setParameters(Object... numberedParamValues);
is that if there is a single (numbered) parameter and it just happens to be of
type java.util.Map then this will go through the former method. Hence
setNamedParameters(Map namedParamMap);
setParameters(Object... numberedParamValues);
> Change Query API to make use of generics to avoid casting execute() results

> The query API is dated, requiring casting of results to the required type.
> Let's make use of generics etc and remove the pain. This will mean changing
> the API so that the resultClass (and possibly more) will need passing into
> the
> execute() method(s). Could also specify parameters via setter rather than
> just on the execute.
> See JDO-652 also, we need to have a consistent way of executing queries
> whether created using strings or typesafe, so that no casting of results is
> needed with either
