Throws:

IOException

nextBackOffMillis

public long nextBackOffMillis()
                       throws IOException

Description copied from interface: BackOff

Gets the number of milliseconds to wait before retrying the operation or BackOff.STOP to indicate that no retries should be made.

Example usage:

   long backOffMillis = backoff.nextBackOffMillis();
   if (backOffMillis == Backoff.STOP) {
     // do not retry operation
   } else {
     // sleep for backOffMillis milliseconds and retry operation
   }
 

Specified by:

nextBackOffMillis in interface BackOff

Throws:

IOException

setBackOffMillis

public MockBackOff setBackOffMillis(long backOffMillis)

Sets the fixed back-off milliseconds (defaults to 0).

Overriding is only supported for the purpose of calling the super implementation and changing the return type, but nothing else.

setMaxTries

public MockBackOff setMaxTries(int maxTries)

Sets the maximum number of tries before returning BackOff.STOP (defaults to 10).

Overriding is only supported for the purpose of calling the super implementation and changing the return type, but nothing else.

getMaxTries

public final int getMaxTries()

Returns the maximum number of tries before returning BackOff.STOP.

getNumberOfTries

public final int getNumberOfTries()

Returns the number of tries so far.
