Detailed Description

template<typename Detector>
struct resilient::StatelessDetector< Detector >

An helper base detector to simplify writing stateless detectors.

It uses the CRT pattern to define the Detector concept, calling the derived Detector detect() method to detect failures.

The detectors which derive from the StatelessDetector need only to define a detect() function which takes the ICallResult.

How to use it

struct MyStatelessDetector : FailureDetectorTag<MyFailure>,
StatelessDetector<MyStatelessDetector>
{
     auto detect(ICallResult<T>& result)
     {
         ...
     }
}

Template Parameters

Detector

The type of the detector

Template Parameters

T	The type returned by the detected function.

Parameters

result

The result of invoking the detected function.

Returns

The result of invoking detect() on the Detector
