It consists of -the following three components: -<ul> - <li>The <font face="Courier New">RateGen</font> component sends periodic - <font face="Courier New">Pulse</font> events to consumers according to the - rate specified in its attribute <font face="Courier New">Rate</font>, it - allows a client (CORBA client <font face="Courier New">controller</font>) to - start and stop the rate generating event.</li> - <li>The <font face="Courier New">GPS</font> component interacts with a GPS - hardware. When the <font face="Courier New">GPS</font> component receives - <font face="Courier New">Refresh</font> events from <font face="Courier New"> - RateGen</font>, it queries the GPS hardware and updates the internal cached - coordination (so that the current location can be read by accessing the - <font face="Courier New">MyLocation</font> interface) and generates an event - on its <font face="Courier New">Ready</font> port to inform the event - consumers that a new GPS reading is available. </li> - <li>The <font face="Courier New">NavDisplay</font> component displays the - current location of the vehicle on the windshield. When a - <font face="Courier New">NavDisplay</font> receives an event notifying the - availability of new data on its <font face="Courier New">Refresh</font> port, - it will acquire the current location of the vehicle by querying the interface - connected to the <font face="Courier New">GPSLocation</font> receptacle.</li> - <li>The <font face="Courier New">NavDisplayGUI</font> directory contains - implementations for a <font face="Courier New">NavDisplay</font> with - graphical interface. To use this graphical interface you need to install qt - libraries and have qt enabled (qt = 1) in your <font face="Courier New">$ACE_ROOT/bin/MakeProjectCreator/config/global.features</font>. - In some Linux distributions qt is installed by default. There is a - non-commercial version of qt libraries for Windows - <a href="http://www.dre.vanderbilt.edu/%7Edengg/ITS/qt-win-noncommercial-msvc-3.2.1.exe"> - here</a> and more information about qt - <a href="http://www.trolltech.com/products/qt/index.html">here</a>. </li> - <li>If you just want to run the application, just go to the last section of - this page.</li> -</ul> -<hr> - -<h2>The files you will find.</h2> - - -<li>1. The interfaces, -data types and exceptions used by the components of this application are -specified in the -<a href="HUDisplay.idl"> <code> -HUDisplay.idl</code></a> file, placed in this example root directory ($CIAO_ROOT/examples/Display). -This is a IDL2 file and uses the familiar CORBA data types. The lib generated -from HUDisplay.idl is linked to all the components of this example. <p></p> - -</li><li>2. mpc files for each of the components -are available in the components directories. We use the <a href="http://downloads.ociweb.com/MPC/MakeProjectCreator.pdf">MPC</a> -to generate makefiles and Visual C++ project/solutions files for all <a href="http://www.cs.wustl.edu/%7Eschmidt/ACE.html">ACE</a>, <a href="http://www.cs.wustl.edu/%7Eschmidt/TAO.html">TAO</a> and <a href="http://www.cs.wustl.edu/%7Eschmidt/CIAO.html">CIAO</a> libraries. - -</li><li>3. idl and cidl files for each component are placed in components directory. </li> - -<li>4. The <code>_exec.h</code> and <code>_exec.cpp</code> files are the actual implementation of the components.</li> - -<li>5. The <code>NavDisplayGUI_exec</code> directory: -<font face="Times New Roman">The <code>NavDisplayGUI_exec.cpp</code> is just an executor version -for NavDisplay. In NavDisplayGUI_exec directory you'll find only the the -NavDisplayGUI_exec (and files for the GUI), which can be deployed with the -NavDisplay stub and servant. So, if you deploy the NavDisplay component -using NavDisplay_exec you'll be able to see the application running in the shell -you triggered the NodeDaemon, and if you deploy the NavDisplay component using -<code>NavDisplayGUI_exec</code> a graphical interface will show you a red dot moving over a -map according to the location being generated by GPS component when you start -the application. Notice that the <code>NavDisplayGUI.mpc</code> file includes <em>qt</em>, used for -graphical interface. You must give the right location of qt libraries in your mpc file.</font> -</li> - -<li>6. The <code>controller</code>: -<font face="Times New Roman">The <code>RateGen</code>component is started and stopped by the <code>controller</code>, a CORBA client application. -The <code>controller</code> source is in <code>RateGen</code> directory, so the <code>RateGen.mpc</code> file also -include instructions for the <code>controller</code> -build.</font> - -</li> - - - -<hr> - -<h3><font size="5">Make</font></h3> -<li>Go to the directory <code>$CIAO_ROOT/DAnCE/examples/Display</code> and do:<br> - <code>$ACE_ROOT/bin/mwc.pl</code> (use -type option if you are using a compiler/IDE other than gnuace -which by default generates GNU makefiles)</li> - <br>For example, using <code>$ACE_ROOT/bin/mwc.pl -type vc71</code> if you are using Visual C++ 7.1 IDE. - - -<hr> - -<h3><font size="5">Assemble</font></h3> -Now we can step forward to build the assembly. - -<li> In the descriptor subdirectory, you'll find a XML descriptor file that describes your <em>deployment plan</em>, the flattened_deploymentplan.cdp: - <dd> -This file declaratively specifies how the component assembly is -constructed.

Each line specify the name of a installation - "destination" and the corresponding IOR for - the CIAO_Daemon. For example, the NodeManagerMap.dat contains: - - AirFrameDevice corbaloc:iiop:localhost:10000/NodeManager - TimerDevice corbaloc:iiop:localhost:12000/NodeManager - - You can copy and modify the copy to deploy the components in various - different locations to let the application truely "distributed". - - Remember to start up the Execution_Manager using the - revised .dat file you created, and start up the CIAO_Daemon according to the specification. - - </li> - - <ul type="square"> <li> <em>NOTE</em>: As one can see, we use the "NodeManagerMap.dat" file to instruct the - Execution_Manager how to find the endpoint of each individual NodeManager (i.e., Node Daemon) where - component(s) will be deployed, so this is non-standard. We plan to use Naming Service to do this in the future. - </li></ul> - - <li> Start the plan_launcher: - <code> $CIAO_ROOT/DAnCE/Plan_Launcher/plan_launcher -p flattened_deploymentplan.cdp -k file://EM.ior </code> - - After this, components should be deployed successfully. - - </li><li> The Assembly_Manager is instructed to write the IOR of the RateGen - component to a file called "rategen.ior" in this - directory. You will then need to use a controller program in a - separate shell window to switch on/off the Rate Generator. - Go to the <em> $CIAO_ROOT/DAnCE/examples/Display/descriptor </em> directory and run the <code>$CIAO_ROOT/DAnCE/examples/Display/RateGen/controller - -o </code> to start the application. To stop the application run <code>$CIAO_ROOT/DAnCE/examples/Display/RateGen/controller - -f </code> - </li> -</ul> - - - -<hr> -<b>Email: </b><a href="mailto:"></a><address>ciao-users@cse.wustl.edu</address> -</body></html> |
