TrackerRepository

TrackerRepository is a global Singleton. 

TrackerRepository<T extends Tracker>

It allows the creation and use of multiple Tracker instances in the same Application.

Properties​

trackersMap​

A Map of all Trackers that have been pushed in the Repository using add.

FYI

makeTracker and getOrMakeTracker automatically push new Tracker instances in the TrackerRepository.

FYI

The first Tracker instance added to the TrackerRepository is also automatically set as default
