Class StreamingRetryAlgorithm<ResponseT> (2.8.1)

public final class StreamingRetryAlgorithm<ResponseT> extends RetryAlgorithm<ResponseT>

The streaming retry algorithm, which makes decision based either on the thrown exception and the execution time settings of the previous attempt. This extends RetryAlgorithm to take additional information (provided by ServerStreamingAttemptCallable) into account.

This class is thread-safe.

Internal use only - public for technical reasons.

Constructors

StreamingRetryAlgorithm(ResultRetryAlgorithm<ResponseT> resultAlgorithm, TimedRetryAlgorithm timedAlgorithm) (deprecated)

public StreamingRetryAlgorithm(ResultRetryAlgorithm<ResponseT> resultAlgorithm, TimedRetryAlgorithm timedAlgorithm)

(deprecated) use #StreamingRetryAlgorithm(ResultRetryAlgorithmWithContext, TimedRetryAlgorithmWithContext) instead

Instances that are created using this constructor will ignore the RetryingContext that is passed in to the retrying methods. Use #StreamingRetryAlgorithm(ResultRetryAlgorithmWithContext, TimedRetryAlgorithmWithContext) to create an instance that will respect the RetryingContext.

Parameters

Name	Description
resultAlgorithm	`ResultRetryAlgorithm<ResponseT>`
timedAlgorithm	`TimedRetryAlgorithm`

StreamingRetryAlgorithm(ResultRetryAlgorithmWithContext<ResponseT> resultAlgorithm, TimedRetryAlgorithmWithContext timedAlgorithm)

public StreamingRetryAlgorithm(ResultRetryAlgorithmWithContext<ResponseT> resultAlgorithm, TimedRetryAlgorithmWithContext timedAlgorithm)

Creates a StreamingRetryAlgorithm that will use the settings (if any) in the RetryingContext that is passed in to the retrying methods.

Parameters

Name	Description
resultAlgorithm	`ResultRetryAlgorithmWithContext<ResponseT>`
timedAlgorithm	`TimedRetryAlgorithmWithContext`

Methods

createNextAttempt(RetryingContext context, Throwable previousThrowable, ResponseT previousResponse, TimedAttemptSettings previousSettings)

public TimedAttemptSettings createNextAttempt(RetryingContext context, Throwable previousThrowable, ResponseT previousResponse, TimedAttemptSettings previousSettings)

Creates a next attempt TimedAttemptSettings. This method will return first non-null value, returned by either result or timed retry algorithms in that particular order.

The attempt settings will be reset if the stream attempt produced any messages.

Parameters

Name	Description
context	`RetryingContext`
previousThrowable	`Throwable`
previousResponse	`ResponseT`
previousSettings	`TimedAttemptSettings`

Returns

Type	Description
TimedAttemptSettings

Overrides

RetryAlgorithm<ResponseT>.createNextAttempt(RetryingContext context, Throwable previousThrowable, ResponseT previousResponse, TimedAttemptSettings previousSettings)

createNextAttempt(Throwable previousThrowable, ResponseT previousResponse, TimedAttemptSettings previousSettings)

public TimedAttemptSettings createNextAttempt(Throwable previousThrowable, ResponseT previousResponse, TimedAttemptSettings previousSettings)

Creates a next attempt TimedAttemptSettings. This method will return first non-null value, returned by either result or timed retry algorithms in that particular order.

The attempt settings will be reset if the stream attempt produced any messages.

Parameters

Name	Description
previousThrowable	`Throwable`
previousResponse	`ResponseT`
previousSettings	`TimedAttemptSettings`

Returns

Type	Description
TimedAttemptSettings

Overrides

RetryAlgorithm<ResponseT>.createNextAttempt(Throwable previousThrowable, ResponseT previousResponse, TimedAttemptSettings previousSettings)

shouldRetry(RetryingContext context, Throwable previousThrowable, ResponseT previousResponse, TimedAttemptSettings nextAttemptSettings)

public boolean shouldRetry(RetryingContext context, Throwable previousThrowable, ResponseT previousResponse, TimedAttemptSettings nextAttemptSettings)

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

Schedules retries only if the StreamResumptionStrategy in the ServerStreamingAttemptCallable supports it.

Parameters

Name	Description
context	`RetryingContext`
previousThrowable	`Throwable`
previousResponse	`ResponseT`
nextAttemptSettings	`TimedAttemptSettings`

Returns

Type	Description
boolean

Overrides

RetryAlgorithm<ResponseT>.shouldRetry(RetryingContext context, Throwable previousThrowable, ResponseT previousResponse, TimedAttemptSettings nextAttemptSettings)

Exceptions

Type	Description
CancellationException

shouldRetry(Throwable previousThrowable, ResponseT previousResponse, TimedAttemptSettings nextAttemptSettings)

public boolean shouldRetry(Throwable previousThrowable, ResponseT previousResponse, TimedAttemptSettings nextAttemptSettings)

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

Ensures retries are only scheduled if the StreamResumptionStrategy in the ServerStreamingAttemptCallable supports it.

Parameters

Name	Description
previousThrowable	`Throwable`
previousResponse	`ResponseT`
nextAttemptSettings	`TimedAttemptSettings`

Returns

Type	Description
boolean

Overrides

RetryAlgorithm<ResponseT>.shouldRetry(Throwable previousThrowable, ResponseT previousResponse, TimedAttemptSettings nextAttemptSettings)

Exceptions

Type	Description
CancellationException
