It + does not indicate that the implementation of components has to be + subsequent to the work we've done under GME. They are totally + orthogonal to each other. In fact, they are so orthogonal + that we won't go into details as to how DAnCE programming should + be done. We'll briefly go through the functionality of each + component and provides the links to their implementations + respectively. For a hands on experience on DAnCE programming, + please refer to $CIAO_ROOT/examples/Hello.<br /> + <br /> + <big><big><small>Broker Component<br /> + </small></big></big> The Broker component + waits to be notified by the Distributor component about stock + changes. When a stock change event arrives, it will go back + to Distributor component and retrieve the information it interest + in and output them to the console. The users are allowed to + subscribe to the interested stock value through the interface + supported by Broker component. Here's the complete version of + <a href="../Quoter/Simple/Broker/Broker_exec.h">Broker_exec.h</a> + and <a href= + "../Quoter/Simple/Broker/Broker_exec.cpp">Broker_exec.cpp</a>.<br /> + + <br /> + <big><big><small>Distributor Component<br /> + </small></big></big> The Distributor component + monitors the real time stock database and publishes events + whenever it detects stock change. In our program, we use a + ACE_Task to simulate this real-life activity. The task + will run in a separate thread and periodically increment the + stock value by 1. In the same time the stock value is + incremented, an <span style= + "font-style: italic;">StockName</span> event along with the name + of the changed stock will be sent.
