public class MessageFormatValueModel
extends AbstractDerivedValueModel

A value model that takes a set of "argument" ValueModels, formats their values into strings, and then inserts these formatted strings into the provided pattern at the appropriate places. Any changes to the "argument" ValueModels will cause this value model to also update.
