9         use APR::Request::Param;
10
11         $arg1 = $req->args('alpha');
12         $body = $req->body;
13         $body->param_class("APR::Request::Param");
14         ok $_->isa("APR::Request::Param") for values %$body;
15
16         @uploads = grep {$_->upload} values %$body;

DESCRIPTION

21       The "APR::Request::Param" module provides base methods for interfacing
22       with libapreq2's param API.  It also provides a few utility functions
23       and constants.
24
25       This manpage documents version 2.13 of the APR::Request::Param,
26       APR::Request::Brigade, and APR::Request::Brigade::IO packages.

OVERLOADS

29       APR::Request::Param
30
31   ""
32           "$param"
33
34       The double-quote interpolation operator maps to
35       "APR::Request::Param::value()".

METHODS

38       APR::Request::Param
39
40   name
41           $param->name()
42
43       Returns the param's name.  This attribute cannot be modified.
44
45   value
46           $param->value()
47
48       Returns the param's value.  This attribute cannot be modified.
49
50   is_tainted
51           $param->is_tainted()
52           $param->is_tainted($set)
53
54       Get/set the param's internal tainted flag.  Note: if the param's
55       charset is APREQ_CHARSET_UTF8 (8), this also activates the SvUTF8_on
56       flag during calls to name() and/or value().
57
58           $tainted = $param->is_tainted;
59           $param->is_tainted(0);
60           ok $param->is_tainted == 0;
61
62   charset
63           $param->charset()
64           $param->charset($set)
65
66       Get/set the param's internal charset.  The charset is a number between
67       0 and 255; the current recognized values are
68
69       0 APREQ_CHARSET_ASCII    (7-bit us-ascii)
70       1 APREQ_CHARSET_LATIN1   (8-bit iso-8859-1)
71       2 APREQ_CHARSET_CP1252   (8-bit Windows-1252)
72       8 APREQ_CHARSET_UTF8     (utf8 encoded Unicode)
73
74       See is_tainted above for info about how APREQ_CHARSET_UTF8 relates to
75       perl's UTF-8 flag.
76
77           $charset = $param->charset;
78           $param->charset(2);
79           ok $param->charset == 2;
80
81   make
82           APR::Request::Param->make($pool, $name, $value)
83
84       Fast XS param constructor.
85
86   info
87           $param->info()
88           $param->info($set)
89
90       Get/set the APR::Table headers for this param.
91
92   upload
93           $param->upload()
94           $param->upload($set)
95
96       Get/set the APR::Brigade file-upload content for this param.
97
98   upload_filename
99           $param->upload_filename()
100
101       Returns the client-side filename associated with this param.
102
103   upload_link
104           $param->upload_link($path)
105
106       Links the file-upload content with the local file named $path.  Creates
107       a hard-link if the spoolfile's (see upload_tempname) temporary
108       directory is on the same device as $path; otherwise this writes a copy.
109
110   upload_slurp
111           $param->upload_slurp($data)
112
113       Reads the entire file-upload content into $data.
114
115   upload_size
116           $param->upload_size()
117
118       Returns the size of the param's file-upload content.
119
120   upload_type
121           $param->upload_type()
122
123       Returns the MIME-type of the param's file-upload content.
124
125   upload_tempname
126           $param->upload_tempname()
127
128       Returns the name of the local spoolfile for this param.
129
130   upload_io
131           $param->upload_io()
132
133       Returns an APR::Request::Brigade::IO object, which can be treated as a
134       non-seekable IO stream.
135
136   upload_fh
137           $param->upload_fh()
138
139       Returns a seekable filehandle representing the file-upload content.

METHODS

142       APR::Request::Brigade
143
144       This class is derived from APR::Brigade, providing additional methods
145       for TIEHANDLE, READ and READLINE.  To be memory efficient, these
146       methods delete buckets from the brigade as soon as their data is
147       actually read, so you cannot "seek" on handles tied to this class.
148       Such handles have semantics similar to that of a read-only socket.
149
150   new, TIEHANDLE
151           APR::Request::Brigade->TIEHANDLE($bb)
152
153       Creates a copy of the bucket brigade represented by $bb, and blesses
154       that copy into the APR::Request::Brigade class.  This provides
155       syntactic sugar for using perl's builtin "read", "readline", and "<>"
156       operations on handles tied to this package:
157
158           use Symbol;
159           $fh = gensym;
160           tie *$fh, "APR::Request::Brigade", $bb;
161           print while <$fh>;
162
163   READ
164           $bb->READ($contents)
165           $bb->READ($contents, $length)
166           $bb->READ($contents, $length, $offset)
167
168       Reads data from the brigade $bb into $contents.  When omitted $length
169       defaults to "-1", which reads the first bucket into $contents.  A
170       positive $length will read in $length bytes, or the remainder of the
171       brigade, whichever is greater. $offset represents the index in $context
172       to read the new data.
173
174   READLINE
175           $bb->READLINE()
176
177       Returns the first line of data from the bride. Lines are terminated by
178       linefeeds (the '\012' character), but we may eventually use $/ instead.
