NAME

6       Email::Simple::Header - the header of an Email::Simple message
7

VERSION

9       version 2.216
10

SYNOPSIS

12         my $email = Email::Simple->new($text);
13
14         my $header = $email->header_obj;
15         print $header->as_string;
16

DESCRIPTION

18       This method implements the headers of an Email::Simple object.  It is a
19       very minimal interface, and is mostly for private consumption at the
20       moment.
21

METHODS

23   new
24         my $header = Email::Simple::Header->new($head, \%arg);
25
26       $head is a string containing a valid email header, or a reference to
27       such a string.  If a reference is passed in, don't expect that it won't
28       be altered.
29
30       Valid arguments are:
31
32         crlf - the header's newline; defaults to CRLF
33
34   as_string
35         my $string = $header->as_string(\%arg);
36
37       This returns a stringified version of the header.
38
39   header_names
40       This method returns a list of the unique header names found in this
41       header, in no particular order.
42
43   header_raw_pairs
44         my @pairs = $header->header_raw_pairs;
45         my $first_name  = $pairs[0];
46         my $first_value = $pairs[1];
47
48       This method returns a list of all the field/value pairs in the header,
49       in the order that they appear in the header.  (Remember: don't try
50       assigning that to a hash.  Some fields may appear more than once!)
51
52   header_pairs
53       header_pairs is another name for header_raw_pairs, which was the
54       original name for the method and which you'll see most often.  In
55       general, though, it's better to be explicit and use header_raw_pairs.
56       (In Email::MIME, header_str_pairs exists for letting the library do the
57       header decoding for you.)
58
59   header_raw
60         my $first_value = $header->header_raw($field);
61         my $nth_value   = $header->header_raw($field, $index);
62         my @all_values  = $header->header_raw($field);
63
64       This method returns the value or values of the given header field.  If
65       the named field does not appear in the header, this method returns
66       false.
67
68   header
69       This method just calls "header_raw".  It's the older name for
70       "header_raw", but it can be a problem because Email::MIME, a subclass
71       of Email::Simple, makes "header" return the header's decoded value.
72
73   header_raw_set
74         $header->header_raw_set($field => @values);
75
76       This method updates the value of the given header.  Existing headers
77       have their values set in place.  Additional headers are added at the
78       end.  If no values are given to set, the header will be removed from to
79       the message entirely.
80
81   header_set
82       header_set is another name for header_raw_set, which was the original
83       name for the method and which you'll see most often.  In general,
84       though, it's better to be explicit and use header_raw_set.  (In
85       Email::MIME, header_str_set exists for letting the library do the
86       header encoding for you.)
87
88   header_raw_prepend
89         $header->header_raw_prepend($field => $value);
90
91       This method adds a new instance of the name field as the first field in
92       the header.
93
94   crlf
95       This method returns the newline string used in the header.
