Library `giop`

GIOP Library supporting a very limited subset of operations

Summary ------- The library currently provides functionality to connect and query the CORBA naming service for a list of available objects.

Overview -------- The library contains the following classes:

o Packet.* - The Packet classes contain specific packets and function to serialize them to strings that can be sent over the wire. Each class may also contain a function to parse the servers response.

o Comm - Implements a number of functions to handle communication over the the socket.

o Helper - A helper class that provides easy access to the rest of the library

Example ------- The following sample code illustrates how scripts can use the Helper class to interface the library:

 helper   = giop.Helper:new(host, port)
 status, err = helper:Connect()
 status, ctx = helper:GetNamingContext()
 status, objs = helper:ListObjects(ctx)

Additional information ---------------------- The implementation is based on packet dumps and the decoding Wireshark provides.

This implementation is tested and known to work against: x Sun's JAVA orbd

Parameters

packet: the GIOP packet as received by the comm exchGIOPPacket function

Return value:

status, always true

["get"] (packet)

Decodes a get response

Parameters

packet: the GIOP packet as received by the comm exchGIOPPacket function

Return values:

status true on success, false on failure
table containing ip and ctx

["list"] (packet)
