ConfigReader Module

This Module provides the following features:

• read values from an xml config file to have them available at server initialization,
• expose above values as process variables; these may connect to other ApplicationCore modules if needed.

Example usage

• A server application using the config reader may look like:

  namespace ctk = ChimeratK
   
  struct Server : public ctk::Application {
    Server() : Application("testserver") {}
    ~Server() { shutdown(); }
   
    ctk::ConfigReader config{this, "config", "validConfig.xml", {"MyTAG"}};
    TestModule testModule{this, "TestModule", "The test module"};
   
    void Server::defineConnections() override;
   
  };

• Values from validConfig.xml can be accessed at server startup:

  Server::Server() {
   auto config_var = config.get<int8_t>("module1/var8");
   auto config_arr = config.get<std::vector<int8>>("module1/submodule/intArray");
   // ...
  }

Configuration will be published as process variables, according to the hierarchy constructed in the configuration file.

XML file structure

• A valid configuration file may look like:

    <configuration>
      <variable name="var8" type="int8" value="-123"/>
      <module name="module1">
        <variable name="var8" type="int8" value="-123"/>
        <module name="submodule">
            <variable name="intArray" type="int32">
            <value i="0" v="10"/>
            <value i="1" v="9"/>
            <value i="2" v="8"/>
            <value i="7" v="3"/>
            <value i="8" v="2"/>
            <value i="9" v="1"/>
            <value i="3" v="7"/>
            <value i="4" v="6"/>
            <value i="5" v="5"/>
            <value i="6" v="4"/>
         </variable>
        </module>
      </module>
    </configuration>
