NAME

Badger::Filesystem::Base - common functionality for Badger::Filesystem modules

SYNOPSIS

package Badger::Filesystem::SomeOtherModule;
use base 'Badger::Filesystem::Base'
# now this module inherits the base class functionality

DESCRIPTION

Badger::Filesystem::Base is a base class module that defines some common functionality shared by Badger::Filesystem and Badger::Filesystem::Path (which itself is the base class for Badger::Filesystem::Directory and Badger::Filesystem::File.

METHODS

init_path(\%config)

Initialisation method which examines the filesystem path specified as a parameter and splits it into volume, directory and name.

init_options(\%config)

Initialisation method which handles the encoding and codec options.

encoding($enc)

This method can be used to get or set the default encoding for a file.

$file->encoding(':utf8');

The encoding will affect all operations that read data from, or write data to the file.

The method can also be used to get or set the default encoding for a directory or filesystem. In this case the option specifies the default encoding for file contained therein.

$directory->encoding(':utf8');
$file = $directory->file('foo.txt');        # has :utf8 encoding set

codec()

This method can be used to get or set the codec used to serialise data to and from a file via the data() method. The codec should be specified by name, using any of the names that Badger::Codecs recognises or can load.

$file->codec('storable');

# first save the data to file
$file->data($some_data_to_save);

# later... load the data back out
my $data = $file->data;

You can use chained codec specifications if you want to pass the data through more than one codec.

$file->code('storable+base64');

See Badger::Codecs for further information on codecs.

As with encoding(), this method can also be used to get or set the default codec for a directory or filesystem.

$directory->codec('json');
$file = $directory->file('foo.json');       # has json codec set
