Mail::Box::Locker::Multi(3pm)				User Contributed Perl Documentation			     Mail::Box::Locker::Multi(3pm)

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
       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 seconds
	     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 (preferrably 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.
