interface HistoryTrackingDelegate (source)
An interface used for providing history information to an engine (e.g. for link highlighting), and receiving history updates from the engine (visits to URLs, title changes).
Even though this interface is defined at the “concept” layer, its get* methods are tailored to two types of engines which we support (system’s WebView and GeckoView).
An engine needs to know “visited” (true/false) status for provided URIs.
An engine needs to know a list of all visited URIs.
Title changed for a given URI.
A URI visit happened that an engine considers worthy of being recorded in browser’s history.
Allows an engine to check if this URI is going to be accepted by the delegate. This helps avoid unnecessary coroutine overhead for URIs which won’t be accepted.
Implementation of the HistoryTrackingDelegate which delegates work to an instance of HistoryStorage.
