Method Detail

fireAndForget

public T fireAndForget()

Executes the work committing if possible and rolling back on failure. On failure, not exception is reported.

oneAndDone

public T oneAndDone()

Executes the work committing if possible and rolling back on failure. On failure an exception is reported.

retry

public T retry()

Executes the work with a default number of retries with a default number of milliseconds delay between each try.

retry

public T retry(int retries)

Executes the work with a specified number of retries with a default number of milliseconds delay between each try.

retry

public T retry(int retries,
      long delayBetweenRetries)

Executes the work with a specified number of retries with a specified number of milliseconds delay between each try.

retry

public T retry(int retries,
      long delayBetweenRetries,
      Set<Class> exceptionsToRetryOn)

Executes the work with a specified number of retries with a specified number of milliseconds delay between each try.

Parameters:

exceptionsToRetryOn - For a retry to happen, it must be in this set of accepted exceptions. If an exception raises that is not in the set, then an error is immediately raised with no retry.

exponentialBackoff

public T exponentialBackoff()

Executes the work with a default number of retries with a exponentially increasing number of milliseconds between each retry.

exponentialBackoff

public T exponentialBackoff(int retries)

Executes the work with a specified number of retries with a exponentially increasing number of milliseconds between each retry.

exponentialBackoff

public T exponentialBackoff(int retries,
                   long initialDelay)

Executes the work with a specified number of retries with a exponentially increasing number of milliseconds between each retry.

exponentialBackoff

public T exponentialBackoff(int retries,
                   long initialDelay,
                   Set<Class> exceptionsToRetryOn)

Executes the work with a specified number of retries with a exponentially increasing number of milliseconds between each retry.

Parameters:

exceptionsToRetryOn - For a retry to happen, it must be in this set of accepted exceptions. If an exception raises that is not in the set, then an error is immediately raised with no retry.

use

public T use(TransactionRetryStrategy<T> strategy)

Executes the work with a specified TransactionRetryStrategy.
