:relfileprefix: ../../../
:mrdocs:

Append the specified `group` of records to the sequence of groups maintained by this sample. If `group.numRecords()` is 0 this method has no effect. The behavior is undefined unless `group.elapsedTime() > bsls::TimeInterval(0, 0)`. Note that the `MetricRecord` objects referred to by `records` are _not_ copied: hence, the supplied array must remain valid for the productive lifetime of this object or until the group is removed by calling `removeAllRecords()`.
