Source code is grouped into the following:
This contains classes related to breadcrumbs. Breadcrumbs are automatically/manually captured
This contains classes related to Client. This is the main interface through which users will interact with Bugsnag, by leaving breadcrumbs, manually notifying of errors, etc.
Contains classes related to the delivery of payloads to the Bugsnag API.
Contains classes related to Metadata, which holds arbitrary metadata added by the user. The Client holds the global state of metadata, which is then copied onto each Event so that it can be mutated/redacted before reports are delivered to the Bugsnag API.
Contains classes which model the payload sent to the Bugsnag API. These are generally structured data which the user can manipulate in callbacks.
Contains code for managing plugins, which can be instantiated and add/modify behaviour tothe notifier.
Code for handling storage of error/session payloads when a network connection is not available or a request cannot be delivered. In this case a report is cached on disk so that it can be delivered in future.
