Method Detail

subscribing

protected void subscribing(UniSerializedSubscriber<? super I> subscriber)

Specified by:

subscribing in class AbstractUni<I>

onSubscribe

public void onSubscribe(UniSubscription subscription)

Description copied from interface: UniSubscriber

Event handler called once the subscribed Uni has taken into account the subscription. The Uni have triggered the computation of the item. IMPORTANT: UniSubscriber.onItem(Object) and UniSubscriber.onFailure(Throwable) would not be called before the invocation of this method.

• Executor: Operate on no particular executor, except if Uni.runSubscriptionOn(Executor) has been called
• Exception: Throwing an exception cancels the subscription, UniSubscriber.onItem(Object) and UniSubscriber.onFailure(Throwable) won't be called

Specified by:

onSubscribe in interface UniSubscriber<I>

Parameters:

subscription - the subscription allowing to cancel the computation.

onItem

public void onItem(I item)

Description copied from interface: UniSubscriber

Event handler called once the item has been computed by the subscribed Uni. IMPORTANT: this method will be only called once per subscription. If UniSubscriber.onFailure(Throwable) is called, this method won't be called.

• Executor: Operate on no particular executor, except if Uni.emitOn(java.util.concurrent.Executor) has been called
• Exception: Throwing an exception cancels the subscription.

Specified by:

onItem in interface UniSubscriber<I>

Parameters:

item - the item, may be null.

onFailure

public void onFailure(Throwable failure)

Description copied from interface: UniSubscriber

Called if the computation of the item by the subscriber Uni failed. IMPORTANT: this method will be only called once per subscription. If UniSubscriber.onItem(Object) is called, this method won't be called.

• Executor: Operate on no particular executor, except if Uni.emitOn(java.util.concurrent.Executor) has been called
• Exception: Throwing an exception cancels the subscription.

Specified by:

onFailure in interface UniSubscriber<I>

Parameters:

failure - the failure, cannot be null.
