I think this RPC addition may be confusing you, as it is infrastructure that defines how individual payloads of AMF data are sent and received from a server.

All of the code is on github. As someone who has built a library that can parse AMF spe make RPC calls RocketAMFI would advise that you use one of the existing libraries rather than write your own if you just need remoting support. This topic describes how LoadComplete supports the protocol.

AMF for use in Moodle is currently being completed within web service infrastructure for Moodle 2. AMF0 RPC calls are composed of a version, list of headers, and list of messages, which roughly equate to methods to call.

The parameter type and the protocol version in which this speec is defined declaration of some types can be different in different protocol versions. AcknowledgeMessageExt As for other objects implementing the IExternalizable interface, LoadComplete does not parse them and does not support modifying data in them.

ActionScript data actually sent for header values or message body values are encoded in AMF. Also, I need people to test amf.

As these parameters store service information for parsing requests sent through the AMF protocol, it is not allowed to change the values of these parameters. All data values start out in AMF 0 for epec sake. Byte arrays, whose size exceeds 50 bytes, are displayed as strings. Shorter byte arrays are displayed as arrays.

It is additional logic for NetConnection based communication to a server. Adobe states that AMF is mainly used to represent object graphs that include named properties in the form of key-value pairs, where the keys are encoded as strings and s;ec values can be of any data type such as strings or numbers as well as arrays and other objects.

It’ll really help us alot. Well on the one side I simply wanted to understand the protocol.
