Interface for observables. This interface is implemented by ObserverRegistry so that classes that want to be observable can implement the interface by delegation:

A helper for classes that want to get observed. This class keeps track of registered observers and can automatically unregister observers if a LifecycleOwner is provided.

Interface for classes that want to intercept load requests to allow custom behavior.

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.

Base class that wraps an non-optional Pointer representing a pointer to a Rust object. This class implements Closeable but does not provide an implementation, forcing all subclasses to implement it. This ensures that all classes that inherit from RustObject will have their Pointer destroyed when the Java wrapper is destroyed.

See SafeIntent for more background: applications can put garbage values into Bundles. This is primarily experienced when there's garbage in the Intent's Bundle. However that Bundle can contain further bundles, and we need to handle those defensively too.

External applications can pass values into Intents that can cause us to crash: in defense, we wrap Intent and catch the exceptions they may force us to throw. See bug 1090385 for more.

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.

This mobile-specific ping is intended to provide the most critical data in a concise format, allowing for frequent uploads. Since this ping is used to measure retention, it should be sent each time the app is opened. https://gecko.readthedocs.io/en/latest/toolkit/components/telemetry/telemetry/data/core-ping.html

TelemetryEvent specifies a common events data format, which allows for broader, shared usage of data processing tools.

A telemetry ping builder for pings of type "focus-event".

Holder of a static reference to the Telemetry instance. This is required for background services that somehow need to get access to the configuration and storage. This is not particular nice. Hopefully we can replace this with something better.

Regular expressions used in this class are taken from Android's Patterns.java. We brought them in to standardize URL matching across Android versions, instead of relying on Android version-dependent built-ins that can vary across Android versions. The original code can be found here: http://androidxref.com/8.0.0_r4/xref/frameworks/base/core/java/android/util/Patterns.java
