ParameterizedMessageFactory	Creates FormattedMessage instances for MessageFactory2 methods (and MessageFactory by extension.)
ParameterizedNoReferenceMessageFactory	Creates FormattedMessage instances for MessageFactory2 methods (and MessageFactory by extension.)
ReusableMessageFactory	Implementation of the MessageFactory interface that avoids allocating temporary objects where possible.
ReusableObjectMessage	Mutable Message wrapper around an Object message.
ReusableParameterizedMessage	Reusable parameterized message.
ReusableSimpleMessage	Mutable Message wrapper around a String message.
SimpleMessage	The simplest possible implementation of Message.
SimpleMessageFactory	Creates FormattedMessage instances for MessageFactory2 methods (and MessageFactory by extension.)
StringFormattedMessage	Handles messages that consist of a format string conforming to Formatter.

Enum	Description
MapMessage.MapFormat	When set as the format specifier causes the Map to be formatted as XML.
