Method Summary

Modifier and Type	Method and Description
int	start(int cycletimeNom) Invoked one time of start of the thread in the thread routine.
int	step(int cycletimeNom, int cycletimeLast, int calctimeLast, long millisecAbs) Invoked cyclically.

Method Detail

start

int start(int cycletimeNom)

Invoked one time of start of the thread in the thread routine.

Returns:

>=0 then it is the wait time for the next step execution (start time). if ==0 then the next step() is executed without wait. <0, especially -1 then waits the cycle time to the first step.

step

int step(int cycletimeNom,
         int cycletimeLast,
         int calctimeLast,
         long millisecAbs)

Invoked cyclically. The cycle is independent of the calculation time of the step if the step calculation time is lesser than the cycle time.

Parameters:

cycletime - the programmed cycle time

lastCalctime - the last need calculation time. The step routine can check whether there is a time overflow.

Returns:

>=0 then waits till the next step with this given time, especially if ==0 then the next step() is executed without wait. <0, especially -1: Executes the next step in exactly the cycle time.
