Class TopicStatsServiceLimitedTimeRetryPolicy (3.7.0-rc)

A retry policy for TopicStatsServiceConnection based on elapsed time.

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

TopicStatsServiceLimitedTimeRetryPolicy(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.
