Method Detail

close

public void close(RetryContext context,
                  RetryCallback callback,
                  Throwable throwable)

Description copied from interface: RetryListener

Called after the final attempt (successful or not). Allow the interceptor to clean up any resource it is holding before control returns to the retry caller.

Specified by:

close in interface RetryListener

Parameters:

context - the current RetryContext.

callback - the current RetryCallback.

throwable - the last exception that was thrown by the callback.

onError

public void onError(RetryContext context,
                    RetryCallback callback,
                    Throwable throwable)

Description copied from interface: RetryListener

Called after every unsuccessful attempt at a retry.

Specified by:

onError in interface RetryListener

Parameters:

context - the current RetryContext.

callback - the current RetryCallback.

throwable - the last exception that was thrown by the callback.

open

public boolean open(RetryContext context,
                    RetryCallback callback)

Description copied from interface: RetryListener

Called before the first attempt in a retry. For instance, implementers can set up state that is needed by the policies in the RetryOperations. The whole retry can be vetoed by returning false from this method, in which case a TerminatedRetryException will be thrown.

Specified by:

open in interface RetryListener

Parameters:

context - the current RetryContext.

callback - the current RetryCallback.

Returns:

true if the retry should proceed.
