+
+GeckoView provides a String representing the entire session state. We
+store this String using a single Map entry with key GECKO_STATE_KEY.
+
+See https://bugzilla.mozilla.org/show_bug.cgi?id=1441810 for
+discussion on sync vs. async, where a decision was made that
+callers should provide synchronous wrappers, if needed. In case we're
+asking for the state when persisting, a separate (independent) thread
+is used so we're not blocking anything else. In case of calling this
+method from onPause or similar, we also want a synchronous response.

+GeckoView provides a String representing the entire session state. We
+store this String using a single Map entry with key GECKO_STATE_KEY.
+
+See https://bugzilla.mozilla.org/show_bug.cgi?id=1441810 for
+discussion on sync vs. async, where a decision was made that
+callers should provide synchronous wrappers, if needed. In case we're
+asking for the state when persisting, a separate (independent) thread
+is used so we're not blocking anything else. In case of calling this
+method from onPause or similar, we also want a synchronous response.

+GeckoView provides a String representing the entire session state. We
+store this String using a single Map entry with key GECKO_STATE_KEY.
+
+See https://bugzilla.mozilla.org/show_bug.cgi?id=1441810 for
+discussion on sync vs. async, where a decision was made that
+callers should provide synchronous wrappers, if needed. In case we're
+asking for the state when persisting, a separate (independent) thread
+is used so we're not blocking anything else. In case of calling this
+method from onPause or similar, we also want a synchronous response.

+| [ReversibleString](-reversible-string/index.html) | `abstract class ReversibleString`<br>A String wrapper utility that allows for efficient string reversal. We regularly need to reverse strings. The standard way of doing this in Java would be to copy the string to reverse (e.g. using StringBuffer.reverse()). This seems wasteful when we only read our Strings character by character, in which case can just transpose positions as needed. |
+| [Trie](-trie/index.html) | `open class Trie`<br>Simple implementation of a Trie, used for indexing URLs. |
+| [UrlMatcher](-url-matcher/index.html) | `class UrlMatcher : OnSharedPreferenceChangeListener`<br>Provides functionality to process categorized URL black/white lists and match URLs against these lists. |

+
+`class BrowserToolbar : ViewGroup, Toolbar`
+
+A customizable toolbar for browsers.
+
+The toolbar can switch between two modes: display and edit. The display mode displays the current
+URL and controls for navigation. In edit mode the current URL can be edited. Those two modes are
+implemented by the DisplayToolbar and EditToolbar classes.

+
+Updates the list of sessions.
+
+Calling this method is usually followed by calling onSession*() methods to indicate what
+exactly has changed. This allows the tabs tray implementation to animate between the old and
+new state.
+
+### Parameters
+
+`sessions` - The list of sessions to be displayed.
+
+`selectedIndex` - The list index of the currently selected session.

+# TelemetryConfiguration
+
+`open class TelemetryConfiguration`
+
+The TelemetryConfiguration class collects the information describing the telemetry setup of an app. There are some parts that every app needs to configure: Where should measurements store data? What servers are we actually uploading pings to? This class should provide good defaults so that in the best case it is not needed to modify the configuration.

+`interface SettingsProvider`
+
+A generic interface for implementations that can provide settings values.
+
+### Functions

+| [release](release.html) | `abstract fun release(): `[`Unit`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html)<br>Notify the provider that we finished reading from it and that it can release resources now. |

+`InlineAutocompleteEditText(ctx: Context, attrs: AttributeSet? = null, defStyleAttr: `[`Int`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html)` = R.attr.editTextStyle)`
+
+A UI edit text component which supports inline autocompletion.
+
+The background color of autocomplete spans can be configured using
+the custom autocompleteBackgroundColor attribute e.g.
+app:autocompleteBackgroundColor="#ffffff".
+
+A filter listener (see [setOnFilterListener](set-on-filter-listener.html)) needs to be attached to
+provide autocomplete results. It will be invoked when the input
+text changes. The listener gets direct access to this component (via its view
+parameter), so it can call {@link applyAutocompleteResult} in return.
+
+A commit listener (see [setOnCommitListener](set-on-commit-listener.html)) can be attached which is
+invoked when the user selected the result i.e. is done editing.
+
+Various other listeners can be attached to enhance default behaviour e.g.
+[setOnSelectionChangedListener](set-on-selection-changed-listener.html) and [setOnWindowsFocusChangeListener](set-on-windows-focus-change-listener.html) which
+will be invoked in response to [onSelectionChanged](on-selection-changed.html) and [onWindowFocusChanged](on-window-focus-changed.html)
