ReactiveUI namespace¶

Part of the ReactiveUI package.

Type	Kind	Summary
AppSupportJsonSuspensionDriver	class	Loads and saves state to persistent storage under the platform Application Support directory.
AutoPersistHelperMixins	class	Collection AutoPersist members and the persistence metadata/driver engine for [AutoPersistHelperMixins](#
AutoPersistMetadata	class	Public-facing persistence metadata for AutoPersist.
AutoSuspendHelper	class	Helps manage android application lifecycle events.
AutoSuspendHelper	class	Bridges iOS lifecycle notifications into [SuspensionHost](# so applications can persist and restore state without manually wiring UIKit events.
BundleSuspensionDriver	class	Loads and saves application state using the platform bundle.
CanActivateViewFetcher	class	This class implements View Activation for classes that explicitly describe their activation via [ICanActivate](# This class is used by the framework.
CollectionViewSectionInformation	class	Class used to extract a common API between `UICollectionView` and `UICollectionViewCell`.
CollectionViewSectionInformation	class	Class used to extract a common API between `UICollectionView` and `UICollectionViewCell`.
CombinedReactiveCommand	class	Encapsulates a composite user interaction.
ContextExtensions	class	Provides extension methods for binding to Android services using observable sequences.
ControlFetcherMixins	class	Extension methods associated with the ControlFetcher class.
DependencyResolverMixins	class	Extension methods associated with the IMutableDependencyResolver interface.
DummySuspensionDriver	class	Provides a no-op implementation of the ISuspensionDriver interface for scenarios where application state persistence is not required.
IActivatableViewModel	interface	Implementing this interface on a ViewModel indicates that the ViewModel is interested in Activation events. Instantiate the Activator, then call WhenActivated on your class to register what you want to happen when the View is activated. See the documentation for ViewModelActivator to read more about Activation.
IActivationForViewFetcher	interface	Implement this interface to override how ReactiveUI determines when a View is activated or deactivated. This is usually only used when porting ReactiveUI to a new UI framework.
ICanActivate	interface	This Interface is used by the framework to explicitly provide activation events. Usually you can ignore this unless you are porting RxUI to a new UI Toolkit.
ILayoutViewHost	interface	Represents a host that provides access to a layout view instance.
IMessageBus	interface	IMessageBus represents an object that can act as a "Message Bus", a simple way for ViewModels and other objects to communicate with each other in a loosely coupled way.
IReactiveObjectExtensions	class	Extension methods associated with the IReactiveObject interface.
IReactiveObjectStateSlot	interface	Exposes a single storage slot on a reactive object so [IReactiveObjectExtensions](# can keep that object's notification state (change/changing/exception subjects, suppression counters) on the instance itself rather than in a process-wide ConditionalWeakTable. This removes a per-notification table lookup and the associated allocations on the hot path.
IRoutableViewModel	interface	Defines the minimum contract for view models that participate in [RoutingState](# navigation.
IScreen	interface	Represents any object capable of hosting its own navigation stack via [RoutingState](#
ISuspensionDriver	interface	Represents a driver capable of loading and saving application state to persistent storage.
ISuspensionHost	interface	ISuspensionHost represents a standardized version of the events that the host operating system publishes. Subscribe to these events in order to handle app suspend / resume.
IViewModule	interface	Represents a module that registers view-to-viewmodel mappings for AOT-compatible view resolution.
IgnoreResourceAttribute	class	Attribute that marks a resource to be ignored.
IndexNormalizer	class	Takes a batch of updates in their natural order (i.e. the order they occurred in the client code) and normalizes them to something iOS can consume when performing batch updates to a table or collection view iOS requires that all deletes be specified first with indexes relative to the source data before any insertions are applied it then requires insertions be specified next relative to the source data after any deletions are applied this code also de-duplicates as necessary. The simplest possible scenario for this is adding and immediately deleting an item. iOS should never even be told about this set of updates because they cancel each other out.

LayoutViewHostUnsafe	class	A [LayoutViewHost](# that can wire its child controls to its properties by reflection.
MessageBus	class	MessageBus represents an object that can act as a "Message Bus", a simple way for ViewModels and other objects to communicate with each other in a loosely coupled way.
