Detailed Description

TimeStamper class provides time services at instanciation, or after by a call to setTime0, the time0, i.e. the reference time that should be called 0 microseconds can be set.

All members are public, but should not be abused!

The services are:

getTimeStamp() returns time in micro secs since t0

getCompensatedTimeStamp(timeStamp_t uTime) returns the uTime (uncompensated time) minus t0, thus the compensated value.

setTime0(timeStamp_t t) sets t0 to the arg.

The class provides a public static instance via the pointer TimeStamper::theTimeStamper. This should be the only instance created.

Constructor & Destructor Documentation

TimeStamper::TimeStamper

(

timeStamp_t

tInit

)

constructor

Parameters

tInit

the value to be used to initialize t0

Member Function Documentation

timeStamp_t TimeStamper::getCompensatedTimeStamp

(

const timeStamp_t &

uTime

)

gets the compensated timestamp of the argument, if the argument is less than t0, resets t0 to 0 micro seconds

Parameters

uTime

a time value

Returns

, uTime- t0 in microsecs

timeStamp_t TimeStamper::getTimeStamp

(

)

gets the current timestamp, i.e. current time - t0 in microsecs if time is less than t0, resets t0 to 0

Returns

timeStamp time

void TimeStamper::setTime0

(

timeStamp_t

t

)

Resets the value of t0 to the arg

Parameters

t	the new value of t0

Field Documentation

timeStamp_t TimeStamper::t0

the zero time in microseconds

TimeStamper * TimeStamper::theTimeStamper = NULL

static

pointer to a public instance of TimeStamper for use by anyone wh o needs it. Only one instance should be needed per slave.
