Interface BackOffPolicy

public interface BackOffPolicy
Interface used to control how fast the mirror and register classes will retry in case of errors. The reset method is used to indicate that all is ok. When things start failing, the get method will be invoked for each new attempt in order to get the appropriate delay between retries (typically increasing for each invocation). The shouldWarn method is used to ask if a certain delay returned from get should result in a warning being logged. When things get back to normal operation, the reset method is invoked to indicate that we are no longer in a failure state.
