Class BasicResultRetryAlgorithm<ResponseT>

java.lang.Object

com.google.api.gax.retrying.BasicResultRetryAlgorithm<ResponseT>

Type Parameters:

ResponseT - attempt response type

All Implemented Interfaces:

ResultRetryAlgorithm<ResponseT>, ResultRetryAlgorithmWithContext<ResponseT>

public class BasicResultRetryAlgorithm<ResponseT>
extends Object
implements ResultRetryAlgorithmWithContext<ResponseT>

A basic implementation of ResultRetryAlgorithm. Using this implementation would mean that all exceptions should be retried, all responses should be accepted (including null) and no retrying process should ever be canceled.

Method Detail

createNextAttempt

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

Always returns null, indicating that this algorithm does not provide any specific settings for the next attempt.

Specified by:

createNextAttempt in interface ResultRetryAlgorithm<ResponseT>

createNextAttempt

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

Always returns null, indicating that this algorithm does not provide any specific settings for the next attempt.

Specified by:

createNextAttempt in interface ResultRetryAlgorithmWithContext<ResponseT>

Parameters:

context - the retrying context of this invocation that can be used to determine the settings for the next attempt.

previousThrowable - exception thrown by the previous attempt (null, if none)

previousResponse - response returned by the previous attempt

previousSettings - previous attempt settings

shouldRetry

public boolean shouldRetry(Throwable previousThrowable,
                           ResponseT previousResponse)

Returns true if an exception was thrown (previousThrowable != null), false otherwise.

Specified by:

shouldRetry in interface ResultRetryAlgorithm<ResponseT>

shouldRetry

public boolean shouldRetry(RetryingContext context,
                           Throwable previousThrowable,
                           ResponseT previousResponse)
                    throws CancellationException

Returns true if an exception was thrown (previousThrowable != null), false otherwise.

Specified by:

shouldRetry in interface ResultRetryAlgorithmWithContext<ResponseT>

Parameters:

context - the retrying context of this invocation that can be used to determine whether the call should be retried.

previousThrowable - exception thrown by the previous attempt (null, if none)

previousResponse - response returned by the previous attempt.

Throws:

CancellationException
