The module defines and classes to capture the execution flow of a processor, including input and output parts, as well as nested processor calls. The class is modified to include a flag. When enabled, the method will record all input and output parts, and any sub-processor calls, into a object managed via . Traces can be saved and loaded from JSON files.
The save_html method exports the trace into a static html file that provide a UI for investigating the trace.
