Class ScheduledRetryingExecutor<ResponseT> (2.19.0)

public class ScheduledRetryingExecutor<ResponseT> implements RetryingExecutorWithContext<ResponseT>

The retry executor which uses ScheduledExecutorService to schedule an attempt tasks.

This implementation does not manage the lifecycle of the underlying ScheduledExecutorService, so it should be managed outside of this class (like calling the ScheduledExecutorService#shutdown() when the pool is not needed anymore). In a typical usage pattern there are usually multiple instances of this class sharing same instance of the underlying ScheduledExecutorService.

This class is thread-safe.

Constructors

ScheduledRetryingExecutor(RetryAlgorithm<ResponseT> retryAlgorithm, ScheduledExecutorService scheduler)

public ScheduledRetryingExecutor(RetryAlgorithm<ResponseT> retryAlgorithm, ScheduledExecutorService scheduler)

Creates a new scheduled retry executor, which will be using scheduler for actual attempts scheduling and retryAlgorithm for retrying strategy.

Parameters

Name	Description
retryAlgorithm	`RetryAlgorithm<ResponseT>` retry algorithm to use
scheduler	`ScheduledExecutorService` scheduler

Methods

createFuture(Callable<ResponseT> callable)

public RetryingFuture<ResponseT> createFuture(Callable<ResponseT> callable)

Creates a RetryingFuture, which is a facade, returned to the client code to wait for any retriable operation to complete. The returned future is bounded to this executor instance.

Parameter

Name	Description
callable	`Callable<ResponseT>` the actual callable, which should be executed in a retriable context

Returns

Type	Description
RetryingFuture<ResponseT>	retrying future facade

createFuture(Callable<ResponseT> callable, RetryingContext context)

public RetryingFuture<ResponseT> createFuture(Callable<ResponseT> callable, RetryingContext context)

Creates a RetryingFuture, which is a facade, returned to the client code to wait for any retriable operation to complete. The returned future is bounded to this executor instance.

Parameters

Name	Description
callable	`Callable<ResponseT>` the actual callable, which should be executed in a retriable context
context	`RetryingContext` the context for this operation

Returns

Type	Description
RetryingFuture<ResponseT>	retrying future facade

submit(RetryingFuture<ResponseT> retryingFuture)

public ApiFuture<ResponseT> submit(RetryingFuture<ResponseT> retryingFuture)

Submits an attempt for execution in a different thread.

Parameter

Name	Description
retryingFuture	`RetryingFuture<ResponseT>` the future previously returned by #createFuture(Callable, RetryingContext)

Returns

Type	Description
com.google.api.core.ApiFuture<ResponseT>	submitted attempt future
