For example, if a caller tries to use a client to make a service * call, but no network connection is present, an AmazonClientException will be * thrown to indicate that the client wasn't able to successfully make the * service call, and no information from the service is available. * * Note : If the SDK is able to parse the response; but doesn't recognize the * error code from the service, an AmazonServiceException is thrown * * Callers should typically deal with exceptions through AmazonServiceException, * which represent error responses returned by services. AmazonServiceException * has much more information available for callers to appropriately deal with * different types of errors that can occur. * * @see AmazonServiceException */ public class AmazonClientException extends SdkBaseException { private static final long serialVersionUID = 1L; /** * Creates a new AmazonClientException with the specified message, and root * cause. * * @param message * An error message describing why this exception was thrown. * @param t * The underlying cause of this exception. */ public AmazonClientException(String message, Throwable t) { super(message, t); } /** * Creates a new AmazonClientException with the specified message. * * @param message * An error message describing why this exception was thrown. */ public AmazonClientException(String message) { super(message); } public AmazonClientException(Throwable t) { super(t); } /** * Returns a hint as to whether it makes sense to retry upon this exception. * Default is true, but subclass may override. * * This method is internal to the SDK.
