Detailed Description

There are a number of parameters (settings) which control the behavior of the Engine.

The default settings of the Engine can be changed, using the OnixS::FIX::EngineSettings class, an external XML-based configuration file or the XML-based configuration string.

To specify configuration which Engine must read, use OnixS::FIX::Engine::init(const OnixS::FIX::EngineSettings& settings), OnixS::FIX::Engine::init(const std::string& configFile) or OnixS::FIX::Engine::initFromString(const std::string& configuration) methods of the OnixS::FIX::Engine class.

Example

Configure the FIX Engine by the OnixS::FIX::EngineSettings class:

using namespace OnixS::FIX;
// Create an instance of the EngineSettings class.
EngineSettings engineSettings;
// Set necessary settings.
engineSettings.dictionaryFile("CmeFastFixDictionary.xml");
engineSettings.licenseFile("licenseFile");
// Invoke the Engine::init with the given EngineSettings class instance.
Engine::init(engineSettings);

Configure the FIX Engine by the external XML-based configuration file:

using namespace OnixS::FIX;
// Invoke the Engine::init with the name of an external XML-based configuration file.
Engine::init("FIX.Engine.config");

Configure the FIX Engine by the XML-based configuration string:

using namespace OnixS::FIX;
// Create an XML-based configuration string.
const char * builtinConfig =
"<configuration>"
"<FixEngine>"
"<add key=\"DictionaryFile\" value=\"CmeFastFixDictionary.xml\"/>"
"<add key=\"LicenseFile\" value=\"licenseFile\"/>"
"</FixEngine>"
"</configuration>";
// Invoke the Engine::initFromString with the given XML-based configuration string.
Engine::initFromString(builtinConfig);
