public class DirectRetryingExecutor<ResponseT> implements RetryingExecutorWithContext<ResponseT>
The retry executor which executes attempts in the current thread, potentially causing the current thread to sleep for the specified amount of time before execution.
This class is thread-safe.
Implements
com.google.api.gax.retrying.RetryingExecutorWithContext<ResponseT>Type Parameter
Name | Description |
ResponseT |
Constructors
DirectRetryingExecutor(RetryAlgorithm<ResponseT> retryAlgorithm)
public DirectRetryingExecutor(RetryAlgorithm<ResponseT> retryAlgorithm)
Creates a new direct retrying executor instance, which will be using retryAlgorithm
to
determine retrying strategy.
Name | Description |
retryAlgorithm | RetryAlgorithm<ResponseT> retry algorithm to use for attempts execution |
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 future is bounded to this
executor instance.
Name | Description |
callable | Callable<ResponseT> the actual callable, which should be executed in a retriable context |
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 future is bounded to this
executor instance.
Name | Description |
callable | Callable<ResponseT> the actual callable, which should be executed in a retriable context |
context | RetryingContext |
Type | Description |
RetryingFuture<ResponseT> | retrying future facade |
sleep(Duration delay)
protected void sleep(Duration delay)
This method simply calls Thread#sleep(long).
Name | Description |
delay | org.threeten.bp.Duration time to sleep |
Type | Description |
InterruptedException | if any thread has interrupted the current thread |
submit(RetryingFuture<ResponseT> retryingFuture)
public ApiFuture<ResponseT> submit(RetryingFuture<ResponseT> retryingFuture)
Submits an attempt for execution in the current thread, causing the current thread to sleep for
the specified by the RetryingFuture#getAttemptSettings() amount of time. As result,
this method completes execution only after the specified retryingFuture
completes.
Name | Description |
retryingFuture | RetryingFuture<ResponseT> the future previously returned by #createFuture(Callable, RetryingContext) |
Type | Description |
com.google.api.core.ApiFuture<ResponseT> | returns completed |
