|
|
* This class will accept any kind of serialized LLSD object, but you
|
|
* probably want to have an array on the outer boundary since this
|
|
* object will interpret each element in the top level LLSD as a
|
|
* parameter into the xmlrpc spec.
|
|
*
|
|
* For example, you would represent 3 params as:
|
|
* <code>
|
|
* {'method'='foo', 'parameter':[i200, r3.4, {"foo":"bar"}]}
|
|
* </code>
|
|
* To generate:
|
|
* <code>
|
|
* <?xml version="1.0"?>
|
|
* <methodCall><params>
|
|
* <param><value><int>200</int></value></param>
|
|
* <param><value><double>3.4</double></value></param>
|
|
* <param><value><struct><member>
|
|
* <name>foo</name><value><string>bar</string></value></member>
|
|
* </struct></value></param>
|
|
* </params></methodCall>
|
|
*
|
|
* This class will accept 2 different kinds of encodings. The first
|
|
* just an array of params as long as you specify the method in the
|
|
* constructor. It will also accept a structured data in the form:
|
|
* {'method':'$method_name', 'parameter':[...] } In the latter form, the
|
|
* encoded 'method' will be used regardless of the construction of the
|
|
* object, and the 'parameter' will be used as parameter to the call.
