Description Torbjorn Norbye 2002-12-26 00:19:46 UTC 
I'd like to see more compiler-error autofixers.
Here are some ideas:
    -- automatically add cast when it's missing
    -- handle length() vs length vs size() confusion
    -- not thrown exceptions - remove try block?
       (beware of finally() clause)
    -- catch uncaught exceptions - can you add try
block
       or does that require too much refactoring
intelligence?
Comment 1 Torbjorn Norbye 2003-02-17 22:15:49 UTC 
length() vs size() confusion is now handled. Whenever you're referring
to an unknown method "length", it checks the target class to see if it
provides a size" method, and if so, offers to use it. And ditto for
"size".
Comment 2 Torbjorn Norbye 2003-03-06 17:36:19 UTC 
It also handles casts now. If you have e.g.
   Object o;
   Integer i = o;
it will offer to insert a cast to make this 
   Integer i = (Integer)o;
and similarly if you have
   ArrayList l = (List)o;
it will offer to change the cast to make this
   ArrayList l = (ArrayList)o;
I think it will also handle casting for parameters in function calls;
I noticed an off-by-one error the other day so I should go back and
check that.
