30 "Email::Abstract" provides module writers with the ability to write
31 simple, representation-independent mail handling code. For instance, in
32 the cases of "Mail::Thread" or "Mail::ListDetector", a key part of the
33 code involves reading the headers from a mail object. Where previously
34 one would either have to specify the mail class required, or to build a
35 new object from scratch, "Email::Abstract" can be used to perform
36 certain simple operations on an object regardless of its underlying
37 representation.
38
39 "Email::Abstract" currently supports "Mail::Internet", "MIME::Entity",
40 "Mail::Message", "Email::Simple", "Email::MIME", and "Courriel". Other
41 representations are encouraged to create their own "Email::Abstract::*"
42 class by copying "Email::Abstract::EmailSimple". All modules installed
43 under the "Email::Abstract" hierarchy will be automatically picked up
44 and used.
45
47 All of these methods may be called either as object methods or as class
48 methods. When called as class methods, the email object (of any class
49 supported by Email::Abstract) must be prepended to the list of
50 arguments, like so:
51
52 my $return = Email::Abstract->method($message, @args);
53
54 This is provided primarily for backwards compatibility.
55
56 new
57 my $email = Email::Abstract->new($message);
58
59 Given a message, either as a string or as an object for which an
60 adapter is installed, this method will return a Email::Abstract object
61 wrapping the message.
62
63 If the message is given as a string, it will be used to construct an
64 object, which will then be wrapped.
65
66 get_header
67 my $header = $email->get_header($header_name);
68
69 my @headers = $email->get_header($header_name);
70
71 This returns the values for the given header. In scalar context, it
72 returns the first value.
73
74 set_header
75 $email->set_header($header => @values);
76
77 This sets the $header header to the given one or more values.
78
79 get_body
80 my $body = $email->get_body;
81
82 This returns the body as a string.
83
84 set_body
85 $email->set_body($string);
86
87 This changes the body of the email to the given string.
88
89 WARNING! You probably don't want to call this method, despite what you
90 may think. Email message bodies are complicated, and rely on things
91 like content type, encoding, and various MIME requirements. If you
92 call "set_body" on a message more complicated than a single-part seven-
93 bit plain-text message, you are likely to break something. If you need
94 to do this sort of thing, you should probably use a specific message
95 class from end to end.
96
97 This method is left in place for backwards compatibility.
98
99 as_string
100 my $string = $email->as_string;
101
102 This returns the whole email as a decoded string.
103
104 cast
105 my $mime_entity = $email->cast('MIME::Entity');
106
107 This method will convert a message from one message class to another.
108 It will throw an exception if no adapter for the target class is known,
109 or if the adapter does not provide a "construct" method.
110
111 object
112 my $message = $email->object;
113
114 This method returns the message object wrapped by Email::Abstract. If
115 called as a class method, it returns false.
116
117 Note that, because strings are converted to message objects before
118 wrapping, this method will return an object when the Email::Abstract
119 was constructed from a string.
