Mail::Mbox::MessageParser::Cache(3pm) User Contributed Perl Documentation Mail::Mbox::MessageParser::Cache(3pm)NAME
Mail::Mbox::MessageParser::Cache - A cache-based mbox folder reader
SYNOPSIS
#!/usr/bin/perl
use Mail::Mbox::MessageParser;
my $filename = 'mail/saved-mail';
my $filehandle = new FileHandle($filename);
# Set up cache
Mail::Mbox::MessageParser::SETUP_CACHE(
{ 'file_name' => '/tmp/cache' } );
my $folder_reader =
new Mail::Mbox::MessageParser( {
'file_name' => $filename,
'file_handle' => $filehandle,
'enable_cache' => 1,
} );
die $folder_reader unless ref $folder_reader;
warn "No cached information"
if $Mail::Mbox::MessageParser::Cache::UPDATING_CACHE;
# Any newlines or such before the start of the first email
my $prologue = $folder_reader->prologue;
print $prologue;
# This is the main loop. It's executed once for each email
while(!$folder_reader->end_of_file());
{
my $email = $folder_reader->read_next_email();
print $email;
}
DESCRIPTION
This module implements a cached-based mbox folder reader. It can only be used when cache information already exists. Users must not
instantiate this class directly--use Mail::Mbox::MessageParser instead. The base MessageParser module will automatically manage the use of
cache and non-cache implementations.
METHODS AND FUNCTIONS
The following methods and functions are specific to the Mail::Mbox::MessageParser::Cache package. For additional inherited ones, see the
Mail::Mbox::MessageParser documentation.
$ref = new( { 'file_name' => <mailbox file name>, 'file_handle' => <mailbox file handle>, });
<file_name> - The full filename of the mailbox
<file_handle> - An opened file handle for the mailbox
The constructor for the class takes two parameters. file_name is the filename of the mailbox. This will be used as the cache key, so
it's important that it fully defines the path to the mailbox. The file_handle argument is the opened file handle to the mailbox. Both
arguments are required.
Returns a reference to a Mail::Mbox::MessageParser object, or a string describing the error.
