public interface DateFormatter
java.text.DateFormat, but for formatting only
(not parsing), and safe for use from multiple threads.
Thread safety: any general-purpose implementation of this interface must be safe for use by multiple concurrent threads. However, thread safety is not necessary if you're making your own implementation and can be sure that any code that uses it (including any code that uses a
RequestProcessor that uses it) will only be called from a single thread.
