RetryAlgorithm

public RetryAlgorithm(ExceptionRetryAlgorithm exceptionAlgorithm,
                      TimedRetryAlgorithm timedAlgorithm)

Creates a new retry algorithm instance, which uses exceptionAlgorithm and timedAlgorithm to make a decision. exceptionAlgorithm has higher priority than the timedAlgorithm.

Parameters:

timedAlgorithm - timed algorithm to use

exceptionAlgorithm - exception algorithm to use

Method Detail

createFirstAttempt

public TimedAttemptSettings createFirstAttempt()

Creates a first attempt TimedAttemptSettings.

Returns:

first attempt settings

createNextAttempt

public TimedAttemptSettings createNextAttempt(Throwable prevThrowable,
                                              TimedAttemptSettings prevSettings)

Creates a next attempt TimedAttemptSettings. This method will return the exception-specific next attempt settings, if there are any, otherwise it will default to the time-specific settings.

Parameters:

prevThrowable - exception thrown by the previous attempt

prevSettings - previous attempt settings

Returns:

next attempt settings
