#include <osaStopwatch.h>
Collaboration diagram for osaStopwatch:
The osaStopwatch class uses system calls to obtain time at the finest granularity available in the system. Note that a system call may sometimes invoke a context switch, and use them only when needed to interfere the least with the normal performance of the program.
To reduce overhead (for more efficient time polling), all the methods are inlined.

| double CISST_EXPORT osaStopwatch::GetTimeGranularity | ( | void | ) | const |
Return the granularity of time in the system, in seconds. The fraction part is the fraction of second that the system time granularity supports
Referenced by Start().
| void osaStopwatch::Reset | ( | void | ) | [inline] |
Reset all the counters to zero, and stop the watch

| void osaStopwatch::Start | ( | void | ) | [inline] |
Start the stopwatch from its current counter state. If the watch is already running, do nothing

| void osaStopwatch::Stop | ( | void | ) | [inline] |
Stop the stopwatch so that its counter state is kept until a Start or a Reset

References IsRunning().
| bool osaStopwatch::IsRunning | ( | void | ) | const [inline] |
Returns true if the stopwatch is running and counting continues (i.e., if Start was called last). Returns false if the watch is stopped, i.e., if Stop or Reset was called last.

| MillisecondsCounter CISST_DEPRECATED osaStopwatch::GetCurrentRead | ( | void | ) | const [inline] |
Return the current read of the stopwatch without changing the running state. This method is now deprecated as it returns a time interval in milliseconds (integer). Use GetElapsedTime() instead.

| SecondsCounter osaStopwatch::GetElapsedTime | ( | void | ) | const [inline] |
Return the current read of the stopwatch without changing the running state. Return a time interval in seconds using a "double" precision floating point number.
