Hi all, not sure if this is the appropriate audience, but I noticed that when I have a StringBuilder, I cannot use any of the optimized format() methods in the java.text APIs (NumberFormat, DateFormat, ChoiceFormat etc)
All those methods only accept a StringBuffer. The obvious change would be to make them accept "Appendable", but that would break to much reflective use of them, wouldn't it? Could an API be added which accepts Appendable? Or is that effort not worth the benefit of using StringBuilder over StringBuffer? Well the JIT might be able to eliminate the locking overhead, however, there is a lot of code out there using StringBuilders, and I would guess they should be able to use the java.text APIs? The sun misc internal APIs support Appendable already (like FloatingDecimal.appendTo) I searched the JDK Bug System and mailing list for this topic, but could not find a suitable hit. If there is such a discussion somewhere, let me know and I will weight in there. Fabian
