io.reactivex.processors

Class AsyncProcessor<T>

java.lang.Object

io.reactivex.Flowable<T>

io.reactivex.processors.FlowableProcessor<T>

io.reactivex.processors.AsyncProcessor<T>

Type Parameters:

T - the value type

All Implemented Interfaces:

FlowableSubscriber<T>, Processor<T,T>, Publisher<T>, Subscriber<T>

public final class AsyncProcessor<T>
extends FlowableProcessor<T>

Processor that emits the very last value followed by a completion event or the received error to Subscribers.

The implementation of onXXX methods are technically thread-safe but non-serialized calls to them may lead to undefined state in the currently subscribed Subscribers.

Method Summary

Modifier and Type	Method and Description
static <T> AsyncProcessor<T>	create() Creates a new AsyncProcessor.
Throwable	getThrowable() Returns the error that caused the FlowableProcessor to terminate or null if the FlowableProcessor hasn't terminated yet.
T	getValue() Returns a single value the Subject currently has or null if no such value exists.
Object[]	getValues() Deprecated. in 2.1.14; put the result of getValue() into an array manually, will be removed in 3.x
T[]	getValues(T[] array) Deprecated. in 2.1.14; put the result of getValue() into an array manually, will be removed in 3.x
boolean	hasComplete() Returns true if the FlowableProcessor has reached a terminal state through a complete event.
boolean	hasSubscribers() Returns true if the FlowableProcessor has subscribers.
boolean	hasThrowable() Returns true if the FlowableProcessor has reached a terminal state through an error event.
boolean	hasValue() Returns true if the subject has any value.
void	onComplete()
void	onError(Throwable t)
void	onNext(T t)
void	onSubscribe(Subscription s) Implementors of this method should make sure everything that needs to be visible in Subscriber.onNext(Object) is established before calling Subscription.request(long).
protected void	subscribeActual(Subscriber<? super T> s) Operator implementations (both source and intermediate) should implement this method that performs the necessary business logic and handles the incoming Subscribers.

subscribe

Method Detail

create

@CheckReturnValue
 @NonNull
public static <T> AsyncProcessor<T> create()

Creates a new AsyncProcessor.

Type Parameters:

T - the value type to be received and emitted

Returns:

the new AsyncProcessor instance

onSubscribe

public void onSubscribe(Subscription s)

Description copied from interface: FlowableSubscriber

Implementors of this method should make sure everything that needs to be visible in Subscriber.onNext(Object) is established before calling Subscription.request(long). In practice this means no initialization should happen after the request() call and additional behavior is thread safe in respect to onNext.

onNext

public void onNext(T t)

onError

public void onError(Throwable t)

onComplete

public void onComplete()

hasSubscribers

public boolean hasSubscribers()

Description copied from class: FlowableProcessor

Returns true if the FlowableProcessor has subscribers.

The method is thread-safe.

Specified by:

hasSubscribers in class FlowableProcessor<T>

Returns:

true if the FlowableProcessor has subscribers

hasThrowable

public boolean hasThrowable()

Description copied from class: FlowableProcessor

Returns true if the FlowableProcessor has reached a terminal state through an error event.

The method is thread-safe.

Specified by:

hasThrowable in class FlowableProcessor<T>

Returns:

true if the FlowableProcessor has reached a terminal state through an error event

See Also:

FlowableProcessor.getThrowable(), FlowableProcessor.hasComplete()

hasComplete

public boolean hasComplete()

Description copied from class: FlowableProcessor

Returns true if the FlowableProcessor has reached a terminal state through a complete event.

The method is thread-safe.

Specified by:

hasComplete in class FlowableProcessor<T>

Returns:

true if the FlowableProcessor has reached a terminal state through a complete event

See Also:

FlowableProcessor.hasThrowable()

getThrowable

@Nullable
public Throwable getThrowable()

Description copied from class: FlowableProcessor

Returns the error that caused the FlowableProcessor to terminate or null if the FlowableProcessor hasn't terminated yet.

The method is thread-safe.

Specified by:

getThrowable in class FlowableProcessor<T>

Returns:

the error that caused the FlowableProcessor to terminate or null if the FlowableProcessor hasn't terminated yet

subscribeActual

protected void subscribeActual(Subscriber<? super T> s)

Description copied from class: Flowable

Operator implementations (both source and intermediate) should implement this method that performs the necessary business logic and handles the incoming Subscribers.

There is no need to call any of the plugin hooks on the current Flowable instance or the Subscriber; all hooks and basic safeguards have been applied by Flowable.subscribe(Subscriber) before this method gets called.

Specified by:

subscribeActual in class Flowable<T>

Parameters:

s - the incoming Subscriber, never null

hasValue

public boolean hasValue()

Returns true if the subject has any value.

The method is thread-safe.

Returns:

true if the subject has any value

getValue

@Nullable
public T getValue()

Returns a single value the Subject currently has or null if no such value exists.

The method is thread-safe.

Returns:

a single value the Subject currently has or null if no such value exists

getValues

@Deprecated
public Object[] getValues()

Deprecated. in 2.1.14; put the result of getValue() into an array manually, will be removed in 3.x

Returns an Object array containing snapshot all values of the Subject.

The method is thread-safe.

Returns:

the array containing the snapshot of all values of the Subject

getValues

@Deprecated
public T[] getValues(T[] array)

Deprecated. in 2.1.14; put the result of getValue() into an array manually, will be removed in 3.x

Returns a typed array containing a snapshot of all values of the Subject.

The method follows the conventions of Collection.toArray by setting the array element after the last value to null (if the capacity permits).

The method is thread-safe.

Parameters:

array - the target array to copy values into if it fits

Returns:

the given array if the values fit into it or a new array containing all values
