java.lang.Objectcom.google.appengine.api.taskqueue.RetryOptions
public final class RetryOptions
Contains various options for a task's retry strategy. Calls to
RetryOptions methods may be chained to specify multiple
options in the one RetryOptions object.
Notes on
usage:
The recommended way to instantiate a RetryOptions object is to statically import RetryOptions.Builder.* and
invoke a static creation method followed by an instance mutator (if
needed):
import static com.google.appengine.api.taskqueue.RetryOptions.Builder.*;
...
RetryOptions retry = withTaskRetryLimit(10).taskAgeLimitSeconds("4d")
.minBackoffSeconds(120).maxBackoffSeconds(3600).maxDoublings(5);
QueueFactory.getDefaultQueue().add(retryOptions(retry));
