NAME

       Mail::Box::Locker::Multi - lock a folder in all ways which work

INHERITANCE

        Mail::Box::Locker::Multi
          is a Mail::Box::Locker
          is a Mail::Reporter

SYNOPSIS

        See Mail::Box::Locker

DESCRIPTION

       The "::Multi" locker locks a folder in each way it can.  This way, the chance is highest
       that any other program will leave the folder alone during our access to it.

       NFS-lock and Flock are tried.  More may be added when the ways to lock are extended.
       DotLock overlaps with NFS-lock, but NFS-lock is safer, so that version is preferred.

METHODS

   Constructors
       Extends "Constructors" in Mail::Box::Locker.

       Mail::Box::Locker::Multi->new(%options)
           You may also pass all %options understood by the initiated lockers used by the multi
           locker.

            -Option --Defined in       --Default
             expires  Mail::Box::Locker  1 hour
             file     Mail::Box::Locker  undef
             folder   Mail::Box::Locker  <undef>
             log      Mail::Reporter     'WARNINGS'
             method   Mail::Box::Locker  'MULTI'
             timeout  Mail::Box::Locker  10
             trace    Mail::Reporter     'WARNINGS'
             use                         <all possible>

           expires => SECONDS
           file => FILENAME
           folder => FOLDER
           log => LEVEL
           method => STRING|CLASS|ARRAY
           timeout => SECONDS|'NOTIMEOUT'
           trace => LEVEL
           use => ARRAY-of-(NAMES|LOCKER)
             Array of locker type NAMES or LOCKER objects to be used to lock one folder.  The
             type NAMES are converted into objects.  When you create your own LOCKER objects, be
             sure to set the timeout very short (preferably to 1).

             Some locking types are not available on some platforms, so they will not be excluded
             from the default list (NFS POSIX Flock).

           example: using a subset of multi-lockers

            my $locker = Mail::Box::Locker::Multi->new(use => ['DOTLOCK','FLOCK']);

DIAGNOSTICS

       Error: Package $package does not implement $method.
           Fatal error: the specific package (or one of its superclasses) does not implement this
           method where it should. This message means that some other related classes do
           implement this method however the class at hand does not.  Probably you should
           investigate this and probably inform the author of the package.
