-/**
- * This class provides a set of callbacks that are invoked when scanning for Broadcast Sources is
- * offloaded to a Broadcast Assistant.
- *
- * <p>An LE Audio Broadcast Assistant can help a Broadcast Sink to scan for available Broadcast
- * Sources. The Broadcast Sink achieves this by offloading the scan to a Broadcast Assistant. This
- * is facilitated by the Broadcast Audio Scan Service (BASS). A BASS server is a GATT server that is
- * part of the Scan Delegator on a Broadcast Sink. A BASS client instead runs on the Broadcast
- * Assistant.
- *
- * <p>Once a GATT connection is established between the BASS client and the BASS server, the
- * Broadcast Sink can offload the scans to the Broadcast Assistant. Upon finding new Broadcast
- * Sources, the Broadcast Assistant then notifies the Broadcast Sink about these over the
- * established GATT connection. The Scan Delegator on the Broadcast Sink can also notify the
- * Assistant about changes such as addition and removal of Broadcast Sources.
