At this +moment, CIAO lacks a CIDL compiler, and we depends on manually +generating the servant glue code for containers and local executor +interface. Check out this <a href="new_components.html">page</a> to +find how all files are generate4d in CIAO. +The following figure shows how this is done:<p> + + +<img src="imgs/File-Gen-Existing.png"><p> + +And when we have a working CIDL (or, CCIDL "CIAO's Component +Implementation Definition Language") compiler, the file will be +generated using a CIDL file (which is rather simple.) This figure +depicts the "Right Way" [TM] this should be done:<p> + +<img src="imgs/File-Gen-Future.png"><p> + +Checkout a <a href="../tools/CCIDL/README">list of things to do</a> for implementing CIDL compiler.<p> + +I think it is debatable whether we should merge the "Servant DLL" and +"Component Implementation DLL" into one DLL. Me think not. My +approach, however, creates some complication on requireing a mechanism +to locate the servant code (and DLL) from component implementation. + + +<h2>Libraries Dependencies</h2> Implementing a component creates 3 +DLL's as shown in the above figure. Both "Servant DLL" and "Component +Implementation DLL" depend on the "Client DLL". "Servant DLL" and +"Component Implementation DLL" are not mutually dependent, however. +All the generated DLLs depends on other TAO and CIAO common +libraries. Here's a break down of which libraries depends on which +other libraries: + +<ul> + <li><b>Client DLL</b>: ace.lib tao.lib TAO_IFR_Client.lib + CIAO_Clientd.lib + <li><b>Servant DLL</b>: ace.lib tao.lib <b>Client DLL</b> + TAO_IFR_Client.lib TAO_PortableServer.lib TAO_Security.lib + CIAO_Container.lib CIAO_Client.lib + <li><b>Component Implementation DLL</b>: ace.lib tao.lib + <b>Client DLL</b> TAO_IFR_Client.lib TAO_Security.lib + CIAO_Container.lib +</ul> + + <!--#include virtual="/~nanbor/signature.html" --> +<!-- <hr> --> +<!-- <\!-- hhmts start -\-> --> +<!-- Last modified: Tue Dec 10 22:41:50 Central Standard Time 2002 --> +<!-- <\!-- hhmts end -\-> --> +<!-- <address>Nanbor Wang <nanbor@cs.wustl.edu></address> --> +</body> </html> |
