## ◆ getStartTime()

const Timestamp & isc::perfmon::DurationDataInterval::getStartTime | ( |  | ) | const
| inline

Get the start time of the interval.

Returns
  Timestamp containing the start time.

Definition at line 54 of file monitored_duration.h.

## ◆ getTotalDuration()

Duration isc::perfmon::DurationDataInterval::getTotalDuration | ( |  | ) | const
| inline

Get the total duration in the interval.

Returns

## ◆ operator==()

bool isc::perfmon::DurationDataInterval::operator== | ( | const DurationDataInterval & | other | ) | const

Equality operator.

Primarily used for testing.

equality operator to compare two DurationDataInterval objects.

Parameters

  other | DurationDataInterval to be compared against.

Returns
  True the keys are equal
