Name

tick_count::interval_t Class — Class for relative wall-clock time.

Synopsis

#include "tbb/tick_count.h"

class tick_count::interval_t;

Description

A tick_count::interval_t represents relative wall-clock time or duration.

Members provide for the accumulation and reduction of intervals by other interval_t values, and for the conversion of interval_t values into seconds.

interval_t()

Effects: constructs an interval_t representing a zero time duration.

doubleseconds()const

Returns: a time interval measured in seconds (can have noninteger values).

interval_t operator+=(const interval_t&i)

Effects: *this = *this+i.

Returns: a reference to *this after the addition.

interval_t operator-=(const interval_t&i)

Effects: *this = *this -i.

Returns: a reference to *this after the subtraction.

interval_t operator+(constinterval_t&i,const interval_t&j)

Returns: an interval_t representing the sum of intervals i and j.

interval_t operator-(constinterval_t&i,const interval_t&j)

Returns: an interval_t representing the difference between intervals i and j.
