NAME

6       Mail::SpamAssassin::Message::Node - decode, render, and make available
7       MIME message parts
8

DESCRIPTION

10       This module will encapsulate an email message and allow access to the
11       various MIME message parts.
12

PUBLIC METHODS

14       new()
15           Generates an empty Node object and returns it.  Typically only
16           called by functions in Message.
17
18       find_parts()
19           Used to search the tree for specific MIME parts.  An array of
20           matching Node objects (pointers into the tree) is returned.  The
21           parameters that can be passed in are (in order, all scalars):
22
23           Regexp - Used to match against each part's Content-Type header,
24           specifically the type and not the rest of the header.  ie:
25           "Content-type: text/html; encoding=quoted-printable" has a type of
26           "text/html".  If no regexp is specified, find_parts() will return
27           an empty array.
28
29           Only_leaves - By default, find_parts() will return any part that
30           matches the regexp, including multipart.  If you only want to see
31           leaves of the tree (ie: parts that aren't multipart), set this to
32           true (1).
33
34           Recursive - By default, when find_parts() finds a multipart which
35           has parts underneath it, it will recurse through all sub-children.
36           If set to 0, only look at the part and any direct children of the
37           part.
38
39       header()
40           Stores and retrieves headers from a specific MIME part.  The first
41           parameter is the header name.  If there is no other parameter, the
42           header is retrieved.  If there is a second parameter, the header is
43           stored.
44
45           Header names are case-insensitive and are stored in both raw and
46           decoded form.  Using header(), only the decoded form is
47           retrievable.
48
49           For retrieval, if header() is called in an array context, an array
50           will be returned with each header entry in a different element.  In
51           a scalar context, the last specific header is returned.
52
53           ie: If 'Subject' is specified as the header, and there are 2
54           Subject headers in a message, the last/bottom one in the message is
55           returned in scalar context or both are returned in array context.
56
57       raw_header()
58           Retrieves the raw version of headers from a specific MIME part.
59           The only parameter is the header name.  Header names are case-
60           insensitive.
61
62           For retrieval, if raw_header() is called in an array context, an
63           array will be returned with each header entry in a different
64           element.  In a scalar context, the last specific header is
65           returned.
66
67           ie: If 'Subject' is specified as the header, and there are 2
68           Subject headers in a message, the last/bottom one in the message is
69           returned in scalar context or both are returned in array context.
70
71       add_body_part()
72           Adds a Node child object to the current node object.
73
74       is_leaf()
75           Returns true if the tree node in question is a leaf of the tree
76           (ie: has no children of its own).  Note: This function may return
77           odd results unless the message has been mime parsed via
78           _do_parse()!
79
80       raw()
81           Return a reference to the raw array.  Treat this as READ ONLY.
82
83       decode()
84           If necessary, decode the part text as base64 or quoted-printable.
85           The decoded text will be returned as a scalar string.  An optional
86           length parameter can be passed in which limits how much decoded
87           data is returned.  If the scalar isn't needed, call with "0" as a
88           parameter.
89
90       rendered()
91           rendered() takes the given text/* type MIME part, and attempts to
92           render it into a text scalar.  It will always render text/html, and
93           will use a heuristic to determine if other text/* parts should be
94           considered text/html.  Two scalars are returned: the rendered type
95           (either text/html or whatever the original type was), and the
96           rendered text.
97
98       set_rendered($text, $type)
99           Set the rendered text and type for the given part.  If type is not
100           specified, and text is a defined value, a default of 'text/plain'
101           is used.  This can be used, for instance, to render non-text parts
102           using plugins.
103
104       visible_rendered()
105           Render and return the visible text in this part.
106
107       invisible_rendered()
108           Render and return the invisible text in this part.
109
110       content_summary()
111           Returns an array of scalars describing the mime parts of the
112           message.  Note: This function requires that the message be parsed
113           first!
114
115       delete_header()
116           Delete the specified header (decoded and raw) from the Node
117           information.
118
119       get_header()
120           Retrieve a specific header.  Will have a newline at the end and
121           will be unfolded.  The first parameter is the header name (case-
122           insensitive), and the second parameter (optional) is whether or not
123           to return the raw header.
124
125           If get_header() is called in an array context, an array will be
126           returned with each header entry in a different element.  In a
127           scalar context, the last specific header is returned.
128
129           ie: If 'Subject' is specified as the header, and there are 2
130           Subject headers in a message, the last/bottom one in the message is
131           returned in scalar context or both are returned in array context.
132
133           Btw, returning the last header field (not the first) happens to be
134           consistent with DKIM signatures, which search for and cover
135           multiple header fields bottom-up according to the 'h' tag. Let's
136           keep it this way.
137
138       get_all_headers()
139           Retrieve all headers.  Each header will have a newline at the end
140           and will be unfolded.  The first parameter (optional) is whether or
141           not to return the raw headers, and the second parameter (optional)
142           is whether or not to include the mbox separator.
143
144           If get_all_header() is called in an array context, an array will be
145           returned with each header entry in a different element.  In a
146           scalar context, the headers are returned in a single scalar.
