public class DefaultConnectionListenerFailureHandler
extends Object
implements ConnectionListenerFailureHandler

Default hander for failures in connection listener IOProcessors. Supports configuration of number retries, delay per retry, and uptime interval considered a success (resets number retries to zero).

Constructor Details

DefaultConnectionListenerFailureHandler

public DefaultConnectionListenerFailureHandler()

Create a new DefaultConnectionListenerFailureHandler with default settings. retryDelay is 1 second, successInterval is 60 seconds, maxRetries is 10

DefaultConnectionListenerFailureHandler

public DefaultConnectionListenerFailureHandler(int retryDelay,
 int successInterval,
 int maxRetries)

Create a new DefaultConnectionListenerFailureHandler

Parameters:

retryDelay - millis to wait before retrying

successInterval - millis after which an initial or retry attempt will be deemed a success, resetting retry count to 0

maxRetries - maximum number of retries allowed without a success, after which the listener will terminate

Method Details

failed

public boolean failed(IOProcessor connectionListener,
 Throwable cause)

Default behavior is to log a warning and attempt retry per constructor config, eventually failing with a logged error and notification. May subclass and override this method to change the behavior.

Specified by:

failed in interface ConnectionListenerFailureHandler

Parameters:

connectionListener - the associated connection listener

cause - cause of failure

Returns:

true if the listener should attempt to re-establish itself, false if it should terminate.

notifyAbnormalTermination

public void notifyAbnormalTermination(IOProcessor connectionListener,
 String message,
 Throwable cause)

Default bevarior is to log the error. May subclass and override this method to change behavior.

Specified by:

notifyAbnormalTermination in interface ConnectionListenerFailureHandler

Parameters:

connectionListener - the associated connection listener

message - explanation of termination

cause - last exception that is causing termination
