public void
onComplete()

Implements io.reactivex.MaybeObserver.onComplete.

Called once the deferred computation completes normally.
public void
onError(Throwable
the exception encountered by the Maybe
e)

Implements io.reactivex.MaybeObserver.onError.

Notifies the MaybeObserver that the Maybe has experienced an error condition.
public void
onSubscribe(Disposable
the Disposable instance whose Disposable#dispose() can be called anytime to cancel the connection
d)

Implements io.reactivex.MaybeObserver.onSubscribe.

Provides the MaybeObserver with the means of cancelling (disposing) the connection (channel) with the Maybe in both synchronous (from within onSubscribe(Disposable) itself) and asynchronous manner.
public void
onSuccess(T
the item emitted by the Maybe
value)

Implements io.reactivex.MaybeObserver.onSuccess.

Notifies the MaybeObserver with one item and that the Maybe has finished sending push-based notifications.
pack-priv void
remove(MaybeCache.CacheDisposable<T> inner)

protected void
subscribeActual(MaybeObserver<? super T>
the MaybeObserver to handle, not null
observer)

Implements abstract io.reactivex.Maybe.subscribeActual.

Implement this method in subclasses to handle the incoming MaybeObservers.

onErrorback to summary
public void onError(Throwable e)

Implements io.reactivex.MaybeObserver.onError.

Doc from io.reactivex.MaybeObserver.onError.

Notifies the MaybeObserver that the Maybe has experienced an error condition.

If the Maybe calls this method, it will not thereafter call onSuccess.

Parameters
e:Throwable

the exception encountered by the Maybe

public void onSubscribe(Disposable d)

Doc from io.reactivex.MaybeObserver.onSubscribe.

Provides the MaybeObserver with the means of cancelling (disposing) the connection (channel) with the Maybe in both synchronous (from within onSubscribe(Disposable) itself) and asynchronous manner.

Parameters
d:Disposable

the Disposable instance whose Disposable#dispose() can be called anytime to cancel the connection

public void onSuccess(T value)

Implements io.reactivex.MaybeObserver.onSuccess.

Doc from io.reactivex.MaybeObserver.onSuccess.

Notifies the MaybeObserver with one item and that the Maybe has finished sending push-based notifications.

The Maybe will not call this method if it calls onError.

Parameters
value:T

the item emitted by the Maybe

subscribeActualback to summary
protected void subscribeActual(MaybeObserver<? super T> observer)

Implements abstract io.reactivex.Maybe.subscribeActual.

Doc from io.reactivex.Maybe.subscribeActual.

Implement this method in subclasses to handle the incoming MaybeObservers.

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

Parameters
observer:MaybeObserver<? super T>

the MaybeObserver to handle, not null
