Class OperationTimedPollAlgorithm (2.7.1)

public class OperationTimedPollAlgorithm extends ExponentialRetryAlgorithm

Operation timed polling algorithm, which uses exponential backoff factor for determining when the next polling operation should be executed. If the polling exceeds the total timeout this algorithm cancels polling.

Methods

create(RetrySettings globalSettings)

public static OperationTimedPollAlgorithm create(RetrySettings globalSettings)

Creates the polling algorithm, using the default NanoClock for time computations.

Parameter

Name	Description
globalSettings	`RetrySettings` the settings

Returns

Type	Description
OperationTimedPollAlgorithm	timed poll algorithm

create(RetrySettings globalSettings, ApiClock clock)

public static OperationTimedPollAlgorithm create(RetrySettings globalSettings, ApiClock clock)

Parameters

Name	Description
globalSettings	`RetrySettings`
clock	`com.google.api.core.ApiClock`

Returns

Type	Description
OperationTimedPollAlgorithm

shouldRetry(TimedAttemptSettings nextAttemptSettings)

public boolean shouldRetry(TimedAttemptSettings nextAttemptSettings)

Returns true if another poll operation should be made or throws CancellationException otherwise.

Parameter

Name	Description
nextAttemptSettings	`TimedAttemptSettings` attempt settings, which will be used for the next attempt, if accepted

Returns

Type	Description
boolean	`true` if more attempts should be made, never returns `false` (throws `CancellationException` instead)

Overrides

ExponentialRetryAlgorithm.shouldRetry(TimedAttemptSettings nextAttemptSettings)

Exceptions

Type	Description
CancellationException	if no more attempts should be made
