BloombergLP::balm::MetricSample::operator=

Assign to this sample the value of the specified rhs sample and return a reference to this modifiable sample. Note that copying the MetricSampleGroup objects contained in rhs copies only the pointers to their respective MetricRecord arrays, and does not copy records themselves; hence, these record arrays must remain valid for the productive lifetimes of all copied objects or until records are removed by calling removeAllRecords.
