relative_time ()

The default constructor creates an interval of 0. relative_time (timetype days, int hours, int minutes, int seconds, int nanoseconds=0)

Construct an interval of a given size. relative_time (timetype seconds, unsigned nanoseconds)

Fast constructor. relative_time operator+ (relative_time that) const

Add two intervals. absolute_time operator+ (absolute_time that) const

Add an interval to a moment. relative_time operator- (relative_time that) const

Subtract two intervals. relative_time operator- () const

Negate an interval. relative_time operator* (float c) const

Scale an interval. relative_time operator/ (float c) const

Scale an interval. relative_time operator% (relative_time that) const

Modulo operator for two intervals. double operator/ (relative_time that) const

Division of two intervals. relative_time & operator+= (relative_time that)

Add an interval. relative_time & operator-= (relative_time that)

Subtract an interval. relative_time & operator*= (float c)

Scale the interval. relative_time & operator/= (float c)

Scale the interval. relative_time & operator%= (relative_time that)

Modulo. bool operator< (relative_time that) const

Compare with another interval. bool operator> (relative_time that) const

Compare with another interval. bool operator<= (relative_time that) const

Compare with another interval. bool operator>= (relative_time that) const

Compare with another interval. bool operator== (relative_time that) const

bool operator!= (relative_time that) const

unsigned nanoseconds () const

Number of nanoseconds. unsigned seconds () const

Number of seconds. unsigned minutes () const

Number of minutes. unsigned hours () const

Number of hours. unsigned days () const

Number of days. bool isnegative () const

Is this a negative interval? timetype total () const

Total number of seconds, as encoded.

Static Public Member Functions

static void set_digits (unsigned num)

Set number of digits to use when printing (for fractions of seconds). static unsigned get_digits ()

Get the number of digits that is used when printing.

Friends

std::ostream & operator<< (std::ostream &s, relative_time t)

Write the interval to a std::ostream.

Time interval.

shevek::relative_time::relative_time (timetypeseconds, unsignednanoseconds)

Fast constructor. This directly fills the members and is therefore slightly faster than the other constructors. However, the others aren't really slow either.

bool shevek::relative_time::operator!= (\fBrelative_time\fPthat) const

Compare two intervals. Note that this is rarely a useful operation, because minor errors may be introduced by computations.

bool shevek::relative_time::operator== (\fBrelative_time\fPthat) const

Compare two intervals. Note that this is rarely a useful operation, because minor errors may be introduced by computations.
