LogMetadata class Sensor Data Source
Provides metadata for a recorded sensor data log.
The LogMetadata object exposes information extracted from a recorded log file such as start/end timestamps and positions, route coordinates, activity details, user-provided metadata, and basic metrics. The LogMetadata class provides information about the recorded log via the Recorder class.
Do not construct this class directly; obtain an instance via RecorderBookmarks.getLogMetadata.
