12.1.4 Writer Implementations
Three implementations of the writer object interface are provided as
examples by this module. Most applications will need to derive new
writer classes from the NullWriter class.
-
A writer which only provides the interface definition; no actions are
taken on any methods. This should be the base class for all writers
which do not need to inherit any implementation methods.
-
A writer which can be used in debugging formatters, but not much
else. Each method simply announces itself by printing its name and
arguments on standard output.
| class DumbWriter( |
[file[, maxcol = 72]]) |
-
Simple writer class which writes output on the file object passed in
as file or, if file is omitted, on standard output. The
output is simply word-wrapped to the number of columns specified by
maxcol. This class is suitable for reflowing a sequence of
paragraphs.
