Craig Russell commented on JDO-446:
-----------------------------------
Two questions.
1. The javadoc for param parameter[s] say
+ * @param parameters the actual values of the subquery parameters
But it isn't the actual values, it's the name of the expression in the outer
query to bind the parameter. The description is ok, but the @param should
probably say
* @param parameter the expression from the outer query to bind the parameter in
the subquery
2. Should we consider one more method, with two arguments, that has the
candidate collection be the extent of the candidate class of the subquery? This
would avoid the need for passing null as the candidateCollectionExpression.
Might be too much of a corner case.
