callWithRetries

public static <V> V callWithRetries(int nAttempts,
                                    int initialRetrySec,
                                    Callable<V> action,
                                    IPredicate<Exception> retryableException)
                             throws Exception

Allows a client to attempt a call and retry a finite amount of times if the exception thrown is the right kind. The retries back off exponentially. For examples: @see com.xeiam.xchange.examples.core.utils.RetriesDemo

Parameters:

nAttempts - Number of attempts before giving up

initialRetrySec - Number of seconds to wait before trying again on the first retry.

action - A callable or lambda expression that contains the code that will be tried and retried, if necessary.

retryableException - An instance of IPredicate that will be used to check if the exception caught is retryable, which can be any complex criteria that the user defines.

Returns:

Throws:

Exception - If the exception isn't retryable, it's immediately thrown again. If it is retryable, then a RunTimeException is thrown after the allowed number of retries is exhausted.
