Typedef Documentation

◆ ObservationPtr

typedef boost::shared_ptr<Observation> isc::stats::ObservationPtr

Observation pointer.

Definition at line 479 of file observation.h.

◆ SampleClock

typedef std::chrono::system_clock isc::stats::SampleClock

Define clock type.

Note
: we use the system clock i.e. the wall clock because this clock can be converted from and to standard Unix time (time_t).

Definition at line 38 of file observation.h.

◆ StatContextPtr

typedef boost::shared_ptr<StatContext> isc::stats::StatContextPtr

Pointer to the statistics context.

Definition at line 85 of file context.h.

◆ StatsDuration

typedef std::chrono::system_clock::duration isc::stats::StatsDuration

Defines duration type.

Note
: the precision depends on the system,

Definition at line 43 of file observation.h.

Function Documentation

◆ toSeconds()

long isc::stats::toSeconds ( const StatsDuration dur)
inline

Returns the number of seconds in a duration.

Parameters
durThe duration.
Returns
The number of seconds in the given duration.

Definition at line 49 of file observation.h.
