public boolean shouldRetry(Throwable t,

Description copied from class: RemoteRetry

Returns true if the caller should attempt to repeat the current remote method call given the number of previous reattempts.

Specified by:

shouldRetry in class RemoteRetry

Parameters:

t - throwable thrown

numRetries - number of previous reattempts

Returns:

true iff call should be repeated, true otherwise

backOff

public void backOff(int numRetries,
                    org.apache.commons.logging.Log log)

Description copied from class: RemoteRetry

Should delay for some implementation defined amount of time (to give the callee, network, etc. time to recover) given the number of previous reattempts. Will be called iff shouldRetry() returned true. Good implementations should implement some sort of increased delay based on the number of reattempts.

Specified by:

backOff in class RemoteRetry

Parameters:

numRetries - number of previous reattempts

log - debug log
