NAME

       Mail::Box::IMAP4::Head - header fields related IMAP interface

INHERITANCE

        Mail::Box::IMAP4::Head
          is a Mail::Message::Head
          is a Mail::Reporter

SYNOPSIS

DESCRIPTION

       This class implements a pure IMAP4 protocol interface, where as little data is retrieved from the header
       as possible.  This may look nice to you, but is not sufficient for many tasks.  For instance, you cannot
       removed or modify fields this way.

       Change Mail::Box::IMAP4::new(cache_head) to "YES" or "DELAY", to get a message header which is capable of
       performing all possible games with headers.  On the other hand: the other settings are not 100% safe...

       See documentation in the base class.

       Mail::Box::IMAP4::Head->new(OPTIONS)
            -Option      --Defined in         --Default
             cache_fields                       false
             field_type    Mail::Message::Head  Mail::Message::Field::Fast

             modified      Mail::Message::Head  <false>
             trace         Mail::Reporter       'WARNINGS'

           cache_fields => BOOLEAN
             This  is only a read-cache on fields, because this kind of header does not allow writing of fields.
             See Mail::Box::IMAP4::new(cache_head), this value is  set  to  "false"  for  "NO"  and  "true"  for
             "PARTIAL"..

           field_type => CLASS
           log => LEVEL
           message => MESSAGE
           modified => BOOLEAN
           trace => LEVEL

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.
