This policy stops retrying if:
- An RPC returns a non-transient error.
- The elapsed time in the retry loop exceeds a prescribed duration.
In this class the following status codes are treated as transient errors:
Constructors
AlertPolicyServiceLimitedTimeRetryPolicy(std::chrono::duration< DurationRep, DurationPeriod >)
Constructor given a std::chrono::duration<>
object.
Parameters |
Name |
Description |
maximum_duration |
std::chrono::duration< DurationRep, DurationPeriod >
the maximum time allowed before the policy expires. While the application can express this time in any units they desire, the class truncates to milliseconds.
|
typename DurationRep |
a placeholder to match the Rep tparam for duration's type. The semantics of this template parameter are documented in std::chrono::duration<> . In brief, the underlying arithmetic type used to store the number of ticks. For our purposes it is simply a formal parameter.
|
typename DurationPeriod |
a placeholder to match the Period tparam for duration's type. The semantics of this template parameter are documented in std::chrono::duration<> . In brief, the length of the tick in seconds, expressed as a std::ratio<> . For our purposes it is simply a formal parameter.
