Class UnicastWorkSubject<T>

java.lang.Object

io.reactivex.rxjava3.core.Observable<T>

io.reactivex.rxjava3.subjects.Subject<T>

hu.akarnokd.rxjava3.subjects.UnicastWorkSubject<T>

Type Parameters:

T - the input and output value type

All Implemented Interfaces:

ObservableSource<T>, Observer<T>, Disposable

public final class UnicastWorkSubject<T>
extends Subject<T>
implements Disposable

A Subject that holds an unbounded queue of items and relays/replays it to a single Observer at a time, making sure that when the Observer disposes, any unconsumed items are available for the next Observer.

This Subject doesn't allow more than one Observers at a time.

The UnicastWorkSubject also allows disconnecting from the optional upstream via dispose().

Since:

0.18.8

Method Detail

create

public static <T> UnicastWorkSubject<T> create()

Constructs an empty UnicastWorkSubject with the default capacity hint (expected number of cached items) of Flowable.bufferSize() and error delaying behavior.

Type Parameters:

T - the input and output value type

Returns:

the new UnicastWorkSubject instance

See Also:

create(int, boolean)

create

public static <T> UnicastWorkSubject<T> create(int capacityHint)

Constructs an empty UnicastWorkSubject with the given capacity hint (expected number of cached items) and error delaying behavior.

Type Parameters:

T - the input and output value type

Parameters:

capacityHint - the number of items expected to be cached, larger number reduces the internal allocation count if the consumer is slow

Returns:

the new UnicastWorkSubject instance

See Also:

create(int, boolean)

create

public static <T> UnicastWorkSubject<T> create(boolean delayErrors)

Constructs an empty UnicastWorkSubject with the given capacity hint (expected number of cached items) of Flowable.bufferSize() and optional error delaying behavior.

Type Parameters:

T - the input and output value type

Parameters:

delayErrors - if true, errors are emitted last

Returns:

the new UnicastWorkSubject instance

See Also:

create(int, boolean)

create

public static <T> UnicastWorkSubject<T> create(int capacityHint,
                                               boolean delayErrors)

Constructs an empty UnicastWorkSubject with the given capacity hint (expected number of cached items) and optional error delaying behavior.

Type Parameters:

T - the input and output value type

Parameters:

capacityHint - the number of items expected to be cached, larger number reduces the internal allocation count if the consumer is slow

delayErrors - if true, errors are emitted last

Returns:

the new UnicastWorkSubject instance
