public interface TimedRetryAlgorithmWithContext extends TimedRetryAlgorithm

A timed retry algorithm is responsible for the following operations, based on the previous attempt settings and current time:

1. Creating first attempt TimedAttemptSettings.
2. Accepting a task for retry so another attempt will be made.
3. Canceling retrying process so the related java.util.concurrent.Future will be canceled.
4. Creating TimedAttemptSettings for each subsequent retry attempt.

Implementations of this interface receive a RetryingContext that can contain specific RetrySettings and retryable codes that should be used to determine the retry behavior.

Implementations of this interface must be be thread-save.

Implements

TimedRetryAlgorithm

Methods

createFirstAttempt(RetryingContext context)

public abstract TimedAttemptSettings createFirstAttempt(RetryingContext context)

Creates a first attempt TimedAttemptSettings.

Parameter

Name	Description
context	RetryingContext a RetryingContext that can contain custom RetrySettings and retryable codes

Returns

Type	Description
TimedAttemptSettings	first attempt settings

createNextAttempt(RetryingContext context, TimedAttemptSettings previousSettings)

public abstract TimedAttemptSettings createNextAttempt(RetryingContext context, TimedAttemptSettings previousSettings)

Creates a next attempt TimedAttemptSettings, which defines properties of the next attempt.

Parameters

Name	Description
context	RetryingContext a RetryingContext that can contain custom RetrySettings and retryable codes
previousSettings	TimedAttemptSettings previous attempt settings

Returns

Type	Description
TimedAttemptSettings	next attempt settings or null if the implementing algorithm does not provide specific settings for the next attempt

shouldRetry(RetryingContext context, TimedAttemptSettings nextAttemptSettings)

public abstract boolean shouldRetry(RetryingContext context, TimedAttemptSettings nextAttemptSettings)

Returns true if another attempt should be made, or false otherwise.

Parameters

Name	Description
context	RetryingContext a RetryingContext that can contain custom RetrySettings and retryable codes.
nextAttemptSettings	TimedAttemptSettings attempt settings, which will be used for the next attempt, if accepted

Returns

Type	Description
boolean
