Method Detail

create

public static RetryPolicy create(javax.interceptor.InvocationContext context,
                                 FaultToleranceConfig config)

isNone

public boolean isNone()

retryOn

public boolean retryOn(Throwable ex)

Should a retry occur then the given Throwable is thrown? Relevant section from Retry javadocs:

When a method returns and the retry policy is present, the following rules are applied:

1. If the method returns normally (doesn't throw), the result is simply returned.
2. Otherwise, if the thrown object is assignable to any value in the #abortOn() parameter, the thrown object is rethrown.
3. Otherwise, if the thrown object is assignable to any value in the #retryOn() parameter, the method call is retried.
4. Otherwise the thrown object is rethrown.

Parameters:

ex - an Error or an Exception

Returns:

true, if a retry should occur, else false.

timeoutTimeNow

public Long timeoutTimeNow()

isDelayed

public boolean isDelayed()

jitteredDelay
