接口 Retry.RetrySignal

封闭类:

Retry

public static interface Retry.RetrySignal

State used in Flux.retryWhen(Retry) and Mono.retryWhen(Retry), providing the Throwable that caused the source to fail as well as counters keeping track of retries.

方法概要

限定符和类型	方法和说明
default Retry.RetrySignal	copy() An immutable copy of this Retry.RetrySignal which is guaranteed to give a consistent view of the state at the time at which this method is invoked.
java.lang.Throwable	failure() The Throwable that caused the current onError signal.
default ContextView	retryContextView() Return a read-only view of the user provided context, which may be used to store objects to be reset/rolled-back or otherwise mutated before or after a retry.
long	totalRetries() The total number of retries since the source first was subscribed to (in other words the number of errors -1 since the source was first subscribed to).
long	totalRetriesInARow() Retry counter resetting after each onNext (in other words the number of errors -1 since the latest onNext).

方法详细资料

totalRetries

long totalRetries()

The total number of retries since the source first was subscribed to (in other words the number of errors -1 since the source was first subscribed to).

返回:

the total number of retries since the source first was subscribed to.

totalRetriesInARow

long totalRetriesInARow()

Retry counter resetting after each onNext (in other words the number of errors -1 since the latest onNext).

返回:

the number of retries since the latest onNext, or the number of retries since the source first was subscribed to if there hasn't been any onNext signals (in which case totalRetries() and totalRetriesInARow() are equivalent).

failure

java.lang.Throwable failure()

The Throwable that caused the current onError signal.

返回:

the current failure.

retryContextView

default ContextView retryContextView()

Return a read-only view of the user provided context, which may be used to store objects to be reset/rolled-back or otherwise mutated before or after a retry.

返回:

a read-only view of a user provided context.

copy

default Retry.RetrySignal copy()

An immutable copy of this Retry.RetrySignal which is guaranteed to give a consistent view of the state at the time at which this method is invoked. This is especially useful if this Retry.RetrySignal is a transient view of the state of the underlying retry subscriber.

返回:

an immutable copy of the current Retry.RetrySignal, always safe to use
