Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Keeps track of formatters for types event that we can use to get the title and body of an event. Formatters should inherit from this class and implement a format(payload) method which returns an array with the title and body.

When implementing a formatter remember that it cannot keep separate state per event, the same object will be called intermittently in a threaded environment. So only keep global configuration as state and pass the payload around as an argument if you need to use helper methods.
