Diff() [1/2]

virtual std::unique_ptr<Aggregation> sdk::metrics::Aggregation::Diff ( const Aggregation &  next ) const

pure virtualnoexcept

Returns a new delta aggregation by comparing two cumulative measurements.

Parameters

next	the newly captured (cumulative) aggregation.

Returns

The resulting delta aggregation.
