io.reactivex.observables

Class ConnectableObservable<T>

java.lang.Object

io.reactivex.Observable<T>

io.reactivex.observables.ConnectableObservable<T>

Type Parameters:

T - the type of items emitted by the ConnectableObservable

All Implemented Interfaces:

ObservableSource<T>

public abstract class ConnectableObservable<T>
extends Observable<T>

A ConnectableObservable resembles an ordinary Observable, except that it does not begin emitting items when it is subscribed to, but only when its connect(io.reactivex.functions.Consumer<? super io.reactivex.disposables.Disposable>) method is called. In this way you can wait for all intended Observers to Observable.subscribe() to the Observable before the Observable begins emitting items.

Methods

Modifier and Type	Method and Description
Observable<T>	autoConnect() Returns an Observable that automatically connects to this ConnectableObservable when the first Observer subscribes.

Observable<T>	autoConnect(int numberOfSubscribers, Consumer<? super Disposable> connection) Returns an Observable that automatically connects to this ConnectableObservable when the specified number of Subscribers subscribe to it and calls the specified callback with the Subscription associated with the established connection.
Disposable	connect() Instructs the ConnectableObservable to begin emitting the items from its underlying Observable to its Observers.
abstract void	connect(Consumer<? super Disposable> connection) Instructs the ConnectableObservable to begin emitting the items from its underlying Observable to its Observers.

Method Detail

connect

public abstract void connect(@NonNull
           Consumer<? super Disposable> connection)

Instructs the ConnectableObservable to begin emitting the items from its underlying Observable to its Observers.

Parameters:

connection - the action that receives the connection subscription before the subscription to source happens allowing the caller to synchronously disconnect a synchronous source

See Also:

ReactiveX documentation: Connect

connect

public final Disposable connect()

Instructs the ConnectableObservable to begin emitting the items from its underlying Observable to its Observers.

To disconnect from a synchronous source, use the connect(Consumer) method.

Returns:

the subscription representing the connection

See Also:

ReactiveX documentation: Connect

refCount

@NonNull
public Observable<T> refCount()

Returns an Observable that stays connected to this ConnectableObservable as long as there is at least one subscription to this ConnectableObservable.

Returns:

an Observable

See Also:

ReactiveX documentation: RefCount

autoConnect

@NonNull
public Observable<T> autoConnect()

Returns an Observable that automatically connects to this ConnectableObservable when the first Observer subscribes.

Returns:

an Observable that automatically connects to this ConnectableObservable when the first Observer subscribes

autoConnect

@NonNull
public Observable<T> autoConnect(int numberOfSubscribers)

Returns an Observable that automatically connects to this ConnectableObservable when the specified number of Observers subscribe to it.

Parameters:

numberOfSubscribers - the number of subscribers to await before calling connect on the ConnectableObservable. A non-positive value indicates an immediate connection.

Returns:

an Observable that automatically connects to this ConnectableObservable when the specified number of Subscribers subscribe to it

autoConnect

@NonNull
public Observable<T> autoConnect(int numberOfSubscribers,
                                @NonNull
                                Consumer<? super Disposable> connection)

Returns an Observable that automatically connects to this ConnectableObservable when the specified number of Subscribers subscribe to it and calls the specified callback with the Subscription associated with the established connection.

Parameters:

numberOfSubscribers - the number of subscribers to await before calling connect on the ConnectableObservable. A non-positive value indicates an immediate connection.

connection - the callback Action1 that will receive the Subscription representing the established connection

Returns:

an Observable that automatically connects to this ConnectableObservable when the specified number of Subscribers subscribe to it and calls the specified callback with the Subscription associated with the established connection
