[Joker-vm-design] java class code guidelines

[Philippe A. <phi...@am...>]

Hi all,

   [ I recall, this is a public and archived mailing list so text must
   be in english... :) ]

   when reading the first bug report, I saw things like this:

   public java.lang.String toString() {
      _value ? new String("true") : new String("false");
   }

   even though I know it was a quick and dummy example, I use this
   opportunity to recall that "new" is to be taken with great care.
   
   roughly, consider it is forbiden to use dynamic allocation in the
   implementation of java classes. this should be left to the
   application programmer as much as possible. also, all constants
   should be "static final" when in java and "static const" in C++. 

   the rationnal behind that is that a memory allocation is slow and
   above all requires a mutex lock wich prevent rigorous control over
   execution. as a consequence it is forbiddent in a self-called
   real-time implementation.


cheers,
