NAME

       Email::Simple::Header - the header of an Email::Simple message

SYNOPSIS

         my $email = Email::Simple->new($text);

         my $header = $email->head;
         print $header->as_string;

DESCRIPTION

       This method implements the headers of an Email::Simple object.  It is a very minimal
       interface, and is mostly for private consumption at the moment.

METHODS

   new
         my $header = Email::Simple::Header->new($head, \%arg);

       $head is a string containing a valid email header, or a reference to such a string.  If a
       reference is passed in, don't expect that it won't be altered.

       Valid arguments are:

         crlf - the header's newline; defaults to CRLF

   as_string
         my $string = $header->as_string(\%arg);

       This returns a stringified version of the header.

   header_names
       This method returns the unique header names found in this header, in no particular order.

   header_pairs
       This method returns all the field/value pairs in the header, in the order that they appear
       in the header.

   header
         my $first_value = $header->header($field);
         my @all_values  = $header->header($field);

       This method returns the value or values of the given header field.  If the named field
       does not appear in the header, this method returns false.

   header_set
         $header->header_set($field => @values);

       This method updates the value of the given header.  Existing headers have their values set
       in place.  Additional headers are added at the end.  If no values are given to set, the
       header will be removed from to the message entirely.

   crlf
       This method returns the newline string used in the header.
