public interface DateTimePrinter
Strategy for printing a calendrical to an appendable.
The printer may print any part, or the whole, of the input Calendrical. Typically, a complete print is constructed from a number of smaller units, each outputting a single field.
DateTimePrinter is an interface and must be implemented with care to ensure other classes in the framework operate correctly. All instantiable implementations must be final, immutable and thread-safe.
