NAME

6       Mail::Mbox::MessageParser::MetaInfo - A cache for folder metadata
7

DESCRIPTION

9       This module implements a cache for meta-information for mbox folders.
10       The information includes such items such as the file position, the line
11       number, and the byte offset of the start of each email.
12
13   METHODS AND FUNCTIONS
14       SETUP_CACHE(...)
15             SETUP_CACHE( { 'file_name' => <cache file name> } );
16
17             <cache file name> - the file name of the cache
18
19           Call this function once to set up the cache before creating any
20           parsers. You must provide the location to the cache file. There is
21           no default value.
22
23           Returns an error string or 1 if there is no error.
24
25       CLEAR_CACHE();
26           Use this function to clear the cache and delete the cache file.
27           Normally you should not need to clear the cache--the module will
28           automatically update the cache when the mailbox changes. Call this
29           function after SETUP_CACHE.
30
31       WRITE_CACHE();
32           Use this function to force the module to write the in-memory cache
33           information to the cache file. Normally you do not need to do
34           this--the module will automatically write the information when the
35           program exits.
36
37       $ref = new( { 'file_name' => <mailbox file name>, 'file_handle' =>
38       <mailbox file handle>, });
39               <file_name> - The full filename of the mailbox
40               <file_handle> - An opened file handle for the mailbox
41
42           The constructor for the class takes two parameters. file_name is
43           the filename of the mailbox. This will be used as the cache key, so
44           it's important that it fully defines the path to the mailbox. The
45           file_handle argument is the opened file handle to the mailbox. Both
46           arguments are required.
47
48           Returns a reference to a Mail::Mbox::MessageParser object, or a
49           string describing the error.
