Overview

The FitDefinition contains the blueprints for FitMessageRecord segments of FIT files. Before a message record can occur in a FIT file, its definition must be included in the FIT file. The definition holds enough information about the message record to define its size. It also contains some basic information how to interpret the data in the record. To fully understand the message record data the full definition in the GlobalFitMessage is required.
