/**

 * no Throwable registered, then this method returns <code>true</code> without
 * checking any further conditions. If there is a Throwable registered, this class
 * checks if the registered Throwable is a retryable Exception in the context of SQL
 * exception. If not successful, this class also checks the cause if there is a nested
 * retryable exception available.
 * <p>
 * Before checking exception this class checks that the current retry count (fetched
 * through {@link org.springframework.retry.RetryContext#getRetryCount()} is smaller
 * or equals to the {@link #maxNumberOfRetries}
 * </p>
 * @param context - the retry context holding information about the retryable
 * operation (number of retries, throwable if any)
 * @return <code>true</code> if there is no throwable registered, if there is a
