Captures the current stacktrace when this publisher is created and makes it available/visible for debugging purposes from the inner Subscriber.

Note that getting a stacktrace is a costly operation.

The operator sanitizes the stacktrace and removes noisy entries such as:

Overrides reactor.core.publisher.InternalMonoOperator.scanUnsafe.

Implements reactor.core.Scannable.scanUnsafe.

This method is used internally by components to define their key-value mappings in a single place.

Implements abstract reactor.core.publisher.InternalMonoOperator.subscribeOrReturn.

Implements reactor.core.publisher.OptimizableOperator.subscribeOrReturn.

Allow delegation of the subscription by returning a CoreSubscriber, or force subscription encapsulation by returning null.

public Object scanUnsafe(Scannable.Attr<T> key)

Overrides reactor.core.publisher.InternalMonoOperator.scanUnsafe.

Implements reactor.core.Scannable.scanUnsafe.

Doc from reactor.core.Scannable.scanUnsafe.

This method is used internally by components to define their key-value mappings in a single place. Although it is ignoring the generic type of the Attr key, implementors should take care to return values of the correct type, and return null if no specific value is available.

For public consumption of attributes, prefer using scan(Attr), which will return a typed value and fall back to the key's default if the component didn't define any mapping.

Parameters
key:Scannable.Attr<T>

a Attr to resolve for the component.

Returns:Object

the value associated to the key for that specific component, or null if none.

public CoreSubscriber<? super T> subscribeOrReturn(CoreSubscriber<? super T> actual)

Implements abstract reactor.core.publisher.InternalMonoOperator.subscribeOrReturn.

Implements reactor.core.publisher.OptimizableOperator.subscribeOrReturn.

Doc from reactor.core.publisher.OptimizableOperator.subscribeOrReturn.

Allow delegation of the subscription by returning a CoreSubscriber, or force subscription encapsulation by returning null. This can be used in conjunction with nextOptimizableSource() to perform subscription in a loop instead of by recursion.

Returns:CoreSubscriber<? super T>

next CoreSubscriber or "null" if the subscription was already done inside the method

Returns a string representation of the object.

Returns:String

a string representation of the object.
