public class ReactiveAdapterRegistry extends Object
Publisher to/from
 various async/reactive types such as CompletableFuture, RxJava
 Observable, and others.
 By default, depending on classpath availability, adapters are registered
 for Reactor, RxJava 1, RxJava 2 types, CompletableFuture, and Java 9+
 Flow.Publisher.
| Constructor and Description | 
|---|
| ReactiveAdapterRegistry()Create a registry and auto-register default adapters. | 
| Modifier and Type | Method and Description | 
|---|---|
| ReactiveAdapter | getAdapter(Class<?> reactiveType)Get the adapter for the given reactive type. | 
| ReactiveAdapter | getAdapter(Class<?> reactiveType,
          Object source)Get the adapter for the given reactive type. | 
| static ReactiveAdapterRegistry | getSharedInstance()Return a shared default  ReactiveAdapterRegistryinstance,
 lazily building it once needed. | 
| boolean | hasAdapters()Whether the registry has any adapters which would be the case if any of
 Reactor, RxJava 2, or RxJava 1 (+ RxJava Reactive Streams bridge) are
 present on the classpath. | 
| void | registerReactiveType(ReactiveTypeDescriptor descriptor,
                    Function<Object,org.reactivestreams.Publisher<?>> toAdapter,
                    Function<org.reactivestreams.Publisher<?>,Object> fromAdapter)Register a reactive type along with functions to adapt to and from a
 Reactive Streams  Publisher. |

 NOTE: We highly recommend passing a long-lived, pre-configured
 ReactiveAdapterRegistry instance for customization purposes.
 This accessor is only meant as a fallback for code paths that want to
 fall back on a default instance if one isn't provided.
