Lightstreamer - Basic Stock-List Demo - C++ Client

This project contains an example of a C++ application that employs the Lightstreamer C++ Client library.

Details

The example provides a very simple version of the Stock-List Demos, where a single subscription to 12 items is submitted. The updates are then formatted and displayed on the console.

The script shows all the basic steps required to establish an interaction to Lightstreamer Server. More specifically, the code comprises these actions:

• Connection to Lightstreamer server and session creation
• Subscription to items with specified fields
• Notification about real time updates
• Unsubscription from items
• Final disconnection

Building

• To build this demo, first install CMake.
• Clone the project Lightstreamer C++ Client library
• Following these instructions, build the statically linked version (with debug symbols) of the Lightstreamer Client SDK.
• Write down the full path to the folder containing the generated C++ source files and binaries (e.g. ~/git/lib-client-haxe/bin/cpp/mac/static-debug).

You can now build the demo executing the following commands:

mkdir build
cd build
cmake .. -DLIGHTSTREAMER_BASE_DIR=<path-to-Lightstreamer-library>
cmake --build .

If you want to install a version of this demo pointing to your local Lightstreamer Server, follow these steps:

• As prerequisite, the Lightstreamer - Stock- List Demo - Java Adapter has to be deployed on your local Lightstreamer Server instance. Please check out that project and follow the installation instructions provided with it.
• Launch Lightstreamer Server.

To start the demo, run the executable build/StockListDemo (or build\Debug\StockListDemo.exe in Windows).

Notes:

• The CMake script is set up to link the demo against the debug version of the Lightstreamer static library. If you need a different configuration, modify the CMakeLists.txt file accordingly.

• The demo is configured to connect to http://push.lightstreamer.com:80, but you can easily change these settings modifying this line LightstreamerClient client("https://push.lightstreamer.com","DEMO"); (in the file src/stock_list_demo.cpp) to connect to the correct combination of host and port of your Lightstreamer server.
