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

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

   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.
