Detailed Description
The TimeKeeper class tracks the passing of time and allows to stop it, restart it, and adjust its speed (only used by ArmarXTimeServer).
Internally the current time is represented as a combination of start time, speed and an offset. The current time (i.e. the output of getTime()) is always (IceUtil::Time::now() - startTime) * speed + offset. When the timer is paused and unpaused or the speed changes, offset gets increased by (IceUtil::Time::now() - starttime) * speed and starttime gets reset to the current time.

◆ getTime()
| IceUtil::Time getTime | ( | ) | const |
get the current time of this clock
- Returns
- the current time. In most cases this should be interpreted as a timedelta, not a datetime.

Here is the caller graph for this function:◆ reset()
| void reset | ( | ) |
resets the clock
Definition at line 50 of file TimeKeeper.cpp.
Here is the caller graph for this function:◆ setSpeed()
| void setSpeed | ( | float | newSpeed | ) |
sets the speed factor of the clock
- Parameters
-
newSpeed new speed factor
Sets how fast the clock is running. e.g. a value of 0.5 means that the clock only ticks with half the speed of the system clock.

Here is the call graph for this function: Here is the caller graph for this function:◆ start()
| void start | ( | ) |
starts the clock
Definition at line 72 of file TimeKeeper.cpp.
Here is the caller graph for this function:◆ step()
| void step | ( | IceUtil::Time | stepSize | ) |
adds a timedelta to the current time
- Parameters
-
stepSize how much to add
Definition at line 92 of file TimeKeeper.cpp.
Here is the caller graph for this function:◆ stop()
| void stop | ( | ) |
stops the clock.
This does not reset the clock.
