| <p>A fixed-size sampler to collect samples over time. AddSample should be called periodically with the sampled value. Samples are added at the max resolution possible. When the sample buffer is full, the current samples are collapsed and the collection period is doubled. The input period and the streaming sampler period do not need to match, the streaming sampler will average values. T is the type of the sample and must be a native numerical type (e.g. int or float). </p> |
