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 This module has a long-term perl support period. That means it will
48 not require a version of perl released fewer than five years ago.
49
50 Although it may work on older versions of perl, no guarantee is made
51 that the minimum required version will not be increased. The version
52 may be increased for any reason, and there is no promise that patches
53 will be accepted to lower the minimum required perl.
54
56 All of these methods may be called either as object methods or as class
57 methods. When called as class methods, the email object (of any class
58 supported by Email::Abstract) must be prepended to the list of
59 arguments, like so:
60
61 my $return = Email::Abstract->method($message, @args);
62
63 This is provided primarily for backwards compatibility.
64
65 new
66 my $email = Email::Abstract->new($message);
67
68 Given a message, either as a string or as an object for which an
69 adapter is installed, this method will return a Email::Abstract object
70 wrapping the message.
71
72 If the message is given as a string, it will be used to construct an
73 object, which will then be wrapped.
74
75 get_header
76 my $header = $email->get_header($header_name);
77
78 my @headers = $email->get_header($header_name);
79
80 This returns the values for the given header. In scalar context, it
81 returns the first value.
82
83 set_header
84 $email->set_header($header => @values);
85
86 This sets the $header header to the given one or more values.
87
88 get_body
89 my $body = $email->get_body;
90
91 This returns the body as a string.
92
93 set_body
94 $email->set_body($string);
95
96 This changes the body of the email to the given string.
97
98 WARNING! You probably don't want to call this method, despite what you
99 may think. Email message bodies are complicated, and rely on things
100 like content type, encoding, and various MIME requirements. If you
101 call "set_body" on a message more complicated than a single-part seven-
102 bit plain-text message, you are likely to break something. If you need
103 to do this sort of thing, you should probably use a specific message
104 class from end to end.
105
106 This method is left in place for backwards compatibility.
107
108 as_string
109 my $string = $email->as_string;
110
111 This returns the whole email as a decoded string.
112
113 cast
114 my $mime_entity = $email->cast('MIME::Entity');
115
116 This method will convert a message from one message class to another.
117 It will throw an exception if no adapter for the target class is known,
118 or if the adapter does not provide a "construct" method.
119
120 object
121 my $message = $email->object;
122
123 This method returns the message object wrapped by Email::Abstract. If
124 called as a class method, it returns false.
125
126 Note that, because strings are converted to message objects before
127 wrapping, this method will return an object when the Email::Abstract
128 was constructed from a string.
