* x Overview - Packages, Handlers and Stages: |
193 |
|
|
* This is weird. ;-) |
194 |
|
|
* - A Package can be instantiated by its namespaced classname |
195 |
|
|
* e.g.: "mkObject('My::Package');" |
196 |
|
|
* - A Package can be a Handler for Data::Driver::Proxy |
197 |
|
|
* - A Handler implements exactly one Stage |
198 |
|
|
* - Data::Driver::Proxy itself embeds these Stages: |
199 |
|
|
* x php4-session |
200 |
|
|
* x rdbms-table |
201 |
|
|
* - An example Handler is Data::Driver::RPC::Remote |
202 |
|
|
* |
203 |
|
|
* x Handlers: |
204 |
|
|
* x Data::Driver::RPC::Remote |
205 |
|
|
* Interacts with a RPC::XML server (todo: talk SOAP!) |
206 |
|
|
* using PEAR::XML::RPC. |
207 |
|
|
* It can cache data for "disconnected mode" using the |
208 |
|
|
* o Data::Driver::phpHtmlLib |
209 |
|

* o Data::Driver::PEAR::DB |
