## Detailed Description

Object that represents an alert.

Alerts are raised at run-time when particular conditions are met, for example bad network quality. The full list of available alert types is described by the Type enum. An application is notified of new alerts through the CoreListener interface. Once raised, the application may use the AlertListener interface to get notified when the alert stops. For each kind of alert, a Dictionary is filled with relevant informations, returned by getInformations(). The keys available are documented per-type in Type enum.
