Description
The base class for all Formatter classes.
A formatter basically takes a Message object and formats it into a string. How the formatting is exactly done is up to the implementation of Formatter. For example, a very simple implementation might simply take the message's Text (see Message::getText()). A useful implementation should at least take the Message's Time, Priority and Text fields and put them into a string.
The Formatter class supports the Configurable interface, so the behaviour of certain formatters is configurable. It also supports reference counting based garbage collection.
Trivial implementations of of getProperty() and setProperty() are provided.
Subclasses must at least provide a format() method.

format
virtual void format(

) const;
Throws a PropertyNotSupportedException.
