AbstractMaybeAsyncHandlerBridge (Asynchronous Http Client RxJava2 Extras 2.12.2 API)

java.lang.Object
- org.asynchttpclient.extras.rxjava2.maybe.AbstractMaybeAsyncHandlerBridge<T>

Type Parameters:

T - the result type produced by the wrapped AsyncHandler and emitted via RxJava

All Implemented Interfaces:

AsyncHandler<Void>

Direct Known Subclasses:

AbstractMaybeProgressAsyncHandlerBridge, MaybeAsyncHandlerBridge
```
public abstract class AbstractMaybeAsyncHandlerBridge<T>
extends Object
implements AsyncHandler<Void>
```
Abstract base class that bridges events between the Maybe reactive base type and AsyncHandlers.
When an event is received, it's first checked if the Rx stream has been disposed asynchronously. If so, request processing is aborted, otherwise, the event is forwarded to the wrapped handler.
When the request is completed, the result produced by the wrapped instance is forwarded to the Maybe: If the result is null, MaybeEmitter.onComplete() is invoked, MaybeEmitter.onSuccess(Object) otherwise.
Any errors during request processing are forwarded via MaybeEmitter.onError(Throwable).

  - onCompleted
```
public final Void onCompleted()
```
    The value returned by the wrapped AsyncHandler won't be returned by this method, but emitted via RxJava.
    
    Specified by:
    
    onCompleted in interface AsyncHandler<Void>
    
    Returns:
    
    always null
  - onThrowable
```
public final void onThrowable(Throwable t)
```
    The exception will first be propagated to the wrapped AsyncHandler, then emitted via RxJava. If the invocation of the delegate itself throws an exception, both the original exception and the follow-up exception will be wrapped into RxJava's CompositeException and then be emitted.
