Cher Mk3 Design -*- outline -*-
|
|
|
|
* Why Cher?
|
|
The basic function of this layer is to allow the sharing (Cher-ing) of
|
|
information among different nodes in the network. Plus, I don't think Cher
|
|
has ever had a software system named after her and it's high time. Imagine
|
|
Cher as the social lubricant that allows the party goers to communicate.
|
|
|
|
* Client components
|
|
|
|
** DObjectManager
|
|
Manages object proxies; converts value change requests into events,
|
|
forwards them via the iomgr; dispatches events on incoming queue; reaps
|
|
proxies when last subscriber goes away
|
|
|
|
** UI (AWT/Swing)
|
|
Standard AWT/Swing UI
|
|
|
|
** UI (Controller)?
|
|
Provides a paradigm of controllers and commands; code can post commands
|
|
back to the controller queue for later execution; UI elements structured
|
|
to automatically generate commands; will probably opt not to use this in
|
|
favor of Swing's built-in paradigms
|
|
|
|
** I/O Manager
|
|
*** Reader
|
|
Reads incoming data from the socket; decodes messages; posts events to
|
|
domgr queue; notifies object subscription penders (this should be done
|
|
asychronously)
|
|
|
|
*** Writer
|
|
Encodes object subscription and event forwarding requests; writes them to
|
|
the outgoing socket
|
|
|
|
** Client object
|
|
Informs exo-client about connection state changes; provides interface to
|
|
connection + authentication (logon) and disconnection (logoff); provides
|
|
access to omgr and client dobj
