/**
|
|
* This is the main class of the proxy. Several threads are started from here:
|
|
* <ul>
|
|
* <li>one single instance of the plasmaSwitchboard is generated, which itself
|
|
* starts a thread with a plasmaHTMLCache object. This object simply counts
|
|
* files sizes in the cache and terminates them. It also generates a
|
|
* plasmaCrawlerLoader object, which may itself start some more httpc-calling
|
|
* threads to load web pages. They terminate automatically when a page has
|
|
* loaded.
|
|
* <li>one serverCore - thread is started, which implements a multi-threaded
|
|
* server. The process may start itself many more processes that handle
|
|
* connections.
|
|
* <li>finally, all idle-dependent processes are written in a queue in
|
|
* plasmaSwitchboard which are worked off inside an idle-sensitive loop of the
|
|
* main process. (here)
|
|
* </ul>
|
|
*
|
|
* On termination, the following must be done:
|
|
* <ul>
|
|
* <li>stop feeding of the crawling process because it othervise fills the
|
|
* indexing queue.
|
|
* <li>say goodbye to connected peers and disable new connections. Don't wait for
|
|
* success.
|
|
* <li>first terminate the serverCore thread. This prevents that new cache
|
|
* objects are queued.
|
|
* <li>wait that the plasmaHTMLCache terminates (it should be normal that this
|
|
* process already has terminated).
|
|
* <li>then wait for termination of all loader process of the
|
|
* plasmaCrawlerLoader.
|
|
* <li>work off the indexing and cache storage queue. These values are inside a
|
|
* RAM cache and would be lost otherwise.
|
|
* <li>write all settings.
|
|
* <li>terminate.
|

* </ul>
