fiftyone.pipeline.engines.trackers.Tracker Interface Reference

Detailed Description

Represents a 'tracker'.

A tracker is a data structure that stores meta-data relating to a key derived from a given FlowData instance. This meta-data is used to determine if the FlowData should continue to be processed or not.

The details of key creation and the specifics of the meta-data are determined by the tracker implementation.

As an example, a tracker could create a key using the source IP address from the FlowData evidence and use the associated meta-data to store a count of the number of times a given source IP has been seen.
