DESCRIPTION

29       Frontier::RPC2 encodes and decodes XML RPC calls.
30
31       $coder = Frontier::RPC2->new( OPTIONS )
32           Create a new encoder/decoder.  The following option is supported:
33
34           encoding
35               The XML encoding to be specified in the XML declaration of
36               encoded RPC requests or responses.  Decoded results may have a
37               different encoding specified; XML::Parser will convert decoded
38               data to UTF-8.  The default encoding is none, which uses XML
39               1.0's default of UTF-8.  For example:
40
41                $server = Frontier::RPC2->new( 'encoding' => 'ISO-8859-1' );
42
43           use_objects
44               If set to a non-zero value will convert incoming <i4>, <float>,
45               and <string> values to objects instead of scalars.  See int(),
46               float(), and string() below for more details.
47
48       $xml_string = $coder->encode_call($method, @args)
49           `"encode_call"' converts a method name and it's arguments into an
50           RPC2 `"methodCall"' element, returning the XML fragment.
51
52       $xml_string = $coder->encode_response($result)
53           `"encode_response"' converts the return value of a procedure into
54           an RPC2 `"methodResponse"' element containing the result, returning
55           the XML fragment.
56
57       $xml_string = $coder->encode_fault($code, $message)
58           `"encode_fault"' converts a fault code and message into an RPC2
59           `"methodResponse"' element containing a `"fault"' element,
60           returning the XML fragment.
61
62       $call = $coder->decode($xml_string)
63           `"decode"' converts an XML string containing an RPC2 `"methodCall"'
64           or `"methodResponse"' element into a hash containing three members,
65           `"type"', `"value"', and `"method_name"'.  `"type"' is one of
66           `"call"', `"response"', or `"fault"'.  `"value"' is array
67           containing the parameters or result of the RPC.  For a `"call"'
68           type, `"value"' contains call's parameters and `"method_name"'
69           contains the method being called.  For a `"response"' type, the
70           `"value"' array contains call's result.  For a `"fault"' type, the
71           `"value"' array contains a hash with the two members `"faultCode"'
72           and `"faultMessage"'.
73
74       $response_xml = $coder->serve($request_xml, $methods)
75           `"serve"' decodes `$request_xml', looks up the called method name
76           in the `$methods' hash and calls it, and then encodes and returns
77           the response as XML.
78
79       $boolean_object = $coder->boolean($boolean);
80       $date_time_object = $coder->date_time($date_time);
81       $base64_object = $coder->base64($base64);
82           These methods create and return XML-RPC-specific datatypes that can
83           be passed to the encoder.  The decoder may also return these
84           datatypes.  The corresponding package names (for use with
85           `"ref()"', for example) are `"Frontier::RPC2::Boolean"',
86           `"Frontier::RPC2::DateTime::ISO8601"', and
87           `"Frontier::RPC2::Base64"'.
88
89           You can change and retrieve the value of boolean, date/time, and
90           base64 data using the `"value"' method of those objects, i.e.:
91
92             $boolean = $boolean_object->value;
93
94             $boolean_object->value(1);
95
96           Note: `"base64()"' does not encode or decode base64 data for you,
97           you must use MIME::Base64 or similar module for that.
98
99       $int_object = $coder->int(42);
100       $float_object = $coder->float(3.14159);
101       $string_object = $coder->string("Foo");
102           By default, you may pass ordinary Perl values (scalars) to be
103           encoded.  RPC2 automatically converts them to XML-RPC types if they
104           look like an integer, float, or as a string.  This assumption
105           causes problems when you want to pass a string that looks like
106           "0096", RPC2 will convert that to an <i4> because it looks like an
107           integer.  With these methods, you could now create a string object
108           like this:
109
110             $part_num = $coder->string("0096");
111
112           and be confident that it will be passed as an XML-RPC string.  You
113           can change and retrieve values from objects using value() as
114           described above.
