Method Summary

Modifier and Type	Method	Description
(package private) void	clearValue()	Override this to clear values when the downstream disposes.
final void	dispose()	Dispose the resource, the operation should be idempotent.
(package private) abstract void	disposeInner()	Typically, this should be inner.dispose().
(package private) abstract void	drain()	Implement the serialized inner subscribing and value emission here.
final boolean	isDisposed()	Returns true if this resource has been disposed.
final void	onComplete()	Notifies the Observer that the Observable has finished sending push-based notifications.
final void	onError(Throwable t)	Notifies the Observer that the Observable has experienced an error condition.
final void	onNext(T t)	Provides the Observer with a new item to observe.
final void	onSubscribe(Disposable d)	Provides the Observer with the means of cancelling (disposing) the connection (channel) with the Observable in both synchronous (from within Observer.onNext(Object)) and asynchronous manner.
(package private) abstract void	onSubscribeDownstream()	Typically, this should be downstream.onSubscribe(this).

ConcatMapXMainObserver

public ConcatMapXMainObserver(int prefetch,
 ErrorMode errorMode)

Method Details

onSubscribe

public final void onSubscribe(Disposable d)

Description copied from interface: Observer

Provides the Observer with the means of cancelling (disposing) the connection (channel) with the Observable in both synchronous (from within Observer.onNext(Object)) and asynchronous manner.

Specified by:

onSubscribe in interface Observer<T>

Parameters:

d - the Disposable instance whose Disposable.dispose() can be called anytime to cancel the connection

onNext

public final void onNext(T t)

Description copied from interface: Observer

Provides the Observer with a new item to observe.

The Observable may call this method 0 or more times.

The Observable will not call this method again after it calls either Observer.onComplete() or Observer.onError(java.lang.Throwable).

Specified by:

onNext in interface Observer<T>

Parameters:

t - the item emitted by the Observable

onError

public final void onError(Throwable t)

Description copied from interface: Observer

Notifies the Observer that the Observable has experienced an error condition.

If the Observable calls this method, it will not thereafter call Observer.onNext(T) or Observer.onComplete().

Specified by:

onError in interface Observer<T>

Parameters:

t - the exception encountered by the Observable

onComplete

public final void onComplete()

Description copied from interface: Observer

Notifies the Observer that the Observable has finished sending push-based notifications.

The Observable will not call this method if it calls Observer.onError(java.lang.Throwable).

Specified by:

onComplete in interface Observer<T>

dispose

public final void dispose()

Description copied from interface: Disposable

Dispose the resource, the operation should be idempotent.

Specified by:

dispose in interface Disposable

isDisposed

public final boolean isDisposed()

Description copied from interface: Disposable

Returns true if this resource has been disposed.

Specified by:

isDisposed in interface Disposable

Returns:

true if this resource has been disposed

clearValue

void clearValue()

Override this to clear values when the downstream disposes.

onSubscribeDownstream

abstract void onSubscribeDownstream()

Typically, this should be downstream.onSubscribe(this).

disposeInner

abstract void disposeInner()

Typically, this should be inner.dispose().

drain

abstract void drain()

Implement the serialized inner subscribing and value emission here.
