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

VERSION
    version 2.216

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

      my $header = $email->header_obj;
      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 a list of the unique header names found in this header, in no particular
    order.

  header_raw_pairs
      my @pairs = $header->header_raw_pairs;
      my $first_name  = $pairs[0];
      my $first_value = $pairs[1];

    This method returns a list of all the field/value pairs in the header, in the order that they
    appear in the header. (Remember: don't try assigning that to a hash. Some fields may appear more
    than once!)

  header_pairs
    header_pairs is another name for header_raw_pairs, which was the original name for the method
    and which you'll see most often. In general, though, it's better to be explicit and use
    header_raw_pairs. (In Email::MIME, header_str_pairs exists for letting the library do the header
    decoding for you.)

  header_raw
      my $first_value = $header->header_raw($field);
      my $nth_value   = $header->header_raw($field, $index);
      my @all_values  = $header->header_raw($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
    This method just calls "header_raw". It's the older name for "header_raw", but it can be a
    problem because Email::MIME, a subclass of Email::Simple, makes "header" return the header's
    decoded value.

  header_raw_set
      $header->header_raw_set($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.

  header_set
    header_set is another name for header_raw_set, which was the original name for the method and
    which you'll see most often. In general, though, it's better to be explicit and use
    header_raw_set. (In Email::MIME, header_str_set exists for letting the library do the header
    encoding for you.)

  header_raw_prepend
      $header->header_raw_prepend($field => $value);

    This method adds a new instance of the name field as the first field in the header.

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