Digests is an abstract class for report-like output that contain several log messages and a title; e.g. an E-mail containing the last 10 log messages before an error was encountered or a push notification.

Abstract classes, only exported for package developers.

Value

Abstract classes cannot be instantiated with $new() and therefore do not return anything. They are solely for developers that want to write their own extension to lgr.
