12.4.2 Formatter Implementations
Two implementations of formatter objects are provided by this module.
Most applications may use one of these classes without modification or
subclassing.
- NullFormatter ([writer])
-
A formatter which does nothing. If writer is omitted, a
NullWriter instance is created. No methods of the writer are
called by NullFormatter instances. Implementations should
inherit from this class if implementing a writer interface but don't
need to inherit any implementation.
- AbstractFormatter (writer)
-
The standard formatter. This implementation has demonstrated wide
applicability to many writers, and may be used directly in most
circumstances. It has been used to implement a full-featured
world-wide web browser.
