perl-Unix-ConfigFile - Unix-ConfigFile - Perl interface to various Unix configuration files
- Description:
The Unix::ConfigFile module provides a base class from which the other
Unix::*File modules are derived. It provides some basic facilities like file
opening, locking, and closing. You do not need to use this module directly
unless you are developing a derived module for an unsupported configuration
file. However, some of the methods documented here are intended for public
use by users of Unix::ConfigFile submodules, so you may find this
documentation useful even if you are not developing your own module.
The ConfigFile object also provides a sequencing API for modules that wish to
preserve the order of the configuration file they read and write. The
sequencer maintains a list of arbitrary data that a submodule may append,
insert, and delete from. Use of the sequencer is completely optional.
A module that subclasses from Unix::ConfigFile must, at a minimum, provide two
methods, called "read" and "write". Both methods will receive a filehandle as
a parameter (besides the regular object parameter). The read method is called
after the file is opened. It is expected to read in the configuration file
and initialize the subclass-specific data structures associated with the
object. The write method is called when an object is committed and is
expected to write out the new configuration to the supplied filehandle.
