Example 1 with ExponentialRetryAlgorithm

use of com.google.api.gax.retrying.ExponentialRetryAlgorithm in project google-cloud-java by GoogleCloudPlatform.

the class RetryHelper method runWithRetries.

public static <V> V runWithRetries(Callable<V> callable, RetrySettings retrySettings, ExceptionHandler exceptionRetryAlgorithm, ApiClock clock) throws RetryHelperException {
    try {
        RetryAlgorithm retryAlgorithm = new RetryAlgorithm(exceptionRetryAlgorithm, new ExponentialRetryAlgorithm(retrySettings, clock));

Example 2 with ExponentialRetryAlgorithm

use of com.google.api.gax.retrying.ExponentialRetryAlgorithm in project java-bigtable by googleapis.
