It turns out that there are some uncooperative methods (those that have a boolean parameter as the second parameter) that don't easily migrate to Java 5 syntax.
Please vote:+1 add new methods that move the boolean parameter to be first and change the Object[ ] to Object...; deprecate the uncooperative methods
-1 keep the uncooperative methods as they are This vote will end on Monday. Here's the discussion.The compiler only autoboxes if the signature is one of the new variable-arity signatures. I took a closer look and found these signatures that can be changed to autobox, simply by changing the signature from [ ] to ...
The implementation would need to change the signature of the implementing class but no other changes would be needed (the type of the argument inside the method remains e.g. Object[ ]).
In PersistenceManager, these methods can be redefined to use variable- arity:
void deletePersistentAll (Object[] pcs);
<T> T[] detachCopyAll (T[] pcs);
void evictAll (Object[] pcs);
Object[] getObjectsById (Object[] oids, boolean validate);
void makeNontransactionalAll (Object[] pcs);
<T> T[] makePersistentAll (T[] pcs);
void makeTransactionalAll (Object[] pcs);
void makeTransientAll (Object[] pcs);
void makeTransientAll (Object[] pcs, boolean useFetchPlan);
void retrieveAll (Object[] pcs, boolean useFetchPlan);
void retrieveAll (Object[] pcs);
In Query:
long deletePersistentAll (Object[] parameters);
Object executeWithArray (Object[] parameters);
One more issue. Variable-arity only works if the variable part is the
last argument. So we either have to reorder the arguments or just not
modify the signature for the methods with extra arguments. So we either:
1. Add new signatures, e.g.
void makeTransientAll (boolean useFetchPlan, Object... pcs);
void makeTransientAll (boolean useFetchPlan, Object... pcs);
void retrieveAll (boolean useFetchPlan, Object... pcs);
2. Don't change the signatures for these methods:
Object[] getObjectsById (Object[] oids, boolean validate);
void makeTransientAll (Object[] pcs, boolean useFetchPlan);
void retrieveAll (Object[] pcs, boolean useFetchPlan);
