:mrdocs:

Append to the sequence of groups maintained by this sample a new group containing the specified sequence of `records` of specified length `numRecords` measuring the specified `elapsedTime`. The behavior is undefined unless `0 <= numRecords`, `records` refers to a contiguous sequence of size (at least) `numRecords`, and `elapsedTime > bsls::TimeInterval(0, 0)`. Note that `records` is _not_ copied: hence, the supplied array must remain valid for the lifetime of this object or until the records are removed by calling `removeAllRecords()`. This method is functionally equivalent to: ` appendGroup(MetricSampleGroup(records, numRecords, elapsedTime)); `
