The Logger application programming interface (API), allows you to extend and customize the functionality available in the Logger.

For example, you can embed a Logger in your own executable to play and record Logger files, or you can build your own version of a Logger executable with your own customizations. You can also use the Logger API to build dynamically linked modules, or plug-ins, that the standard Logger executable can load at runtime.

Note: You must have a VR-Link developer’s license to build applications or plug-ins that use the Logger API.

The Logger API is logically separated into logging functionality and application functionality. Logging functionality involves the low level classes responsible for recording simulation data and playing it back. The application functionality provides a GUI, configuration file loader, and other high-level end-user functionality. The API is designed to be extensible, to make it easier to replace or extend both low-level and high-level functionality.

If your goal in using the Logger API is to add standard Logger features to your own application, the DtLogger and DtLgrInterface classes may be the only portion of the API that you need to understand. (It is possible to use the DtLogger class alone, without any corresponding Logger interface components. However, you would need to implement a way to control the logging process.)

You can use the Logger API as a starting point for writing your own data logging application that uses whichever components of the Logger application that you want. However, you will be limited by project dependencies. For example, if you do not want to use the Qt Toolkit for your GUI library, you cannot use the Logger GUI libraries.

You can extend the Logger application’s functionality. Possible extensions could include new file formats, data inputs and outputs, or additional processing of data within the Logger. You can extend the application by completely rebuilding it, or by writing plug-ins.
