Detailed Description

Based on seal::TimeSpan.

A difference between two Time values. In addition to supporting normal integer artihmetic and comparisons, the span can also be converted to a number useful units.

Constructor & Destructor Documentation

Gaudi::TimeSpan::TimeSpan ( )

default

Initialize an empty (zero) time difference.

Gaudi::TimeSpan::TimeSpan ( Time  t )

inline

Initialize a time span from Time t.

Definition at line 71 of file Time.icpp.

: m_nsecs (t.m_nsecs) {}

Gaudi::TimeSpan::TimeSpan ( ValueType  nsecs )

inline

Initialize a time span to a specific length.

Definition at line 74 of file Time.icpp.

: m_nsecs (nsecs) {}

Gaudi::TimeSpan::TimeSpan ( ValueType  secs, int  nsecs  )

inline

Initialise a time span to a specific length.

The value is initialised to the sum of the parts—the parts do not need to fall into their "natural" ranges. The values are normalised to the natural meanings (e.g. 1000 seconds - 500 nanoseconds), so be careful with signs if you are producing values from other sources.

Parameters

secs	Seconds.
nsecs	Nanoseconds.

Definition at line 84 of file Time.icpp.

    : m_nsecs(secs * Time::SEC_NSECS + nsecs) {}

Gaudi::TimeSpan::TimeSpan ( int  days, int  hours, int  mins, int  secs, int  nsecs  )

inline

Initialise a time span to a specific length.

The value is initialised to the sum of the parts—the parts do not need to fall into their "natural" ranges. The values are normalised to the natural meanings (e.g. 1000 seconds - 500 nanoseconds), so be careful with signs if you are producing values from other sources.

Parameters

days	Whole days.
hours	Whole hours.
mins	Whole minutes.
secs	Whole seconds.
nsecs	Nanoseconds.

Definition at line 98 of file Time.icpp.

    m_nsecs = (secs + 60 * (mins + 60 * (hours + 24*days)))*Time::SEC_NSECS + nsecs;
  }
