class Chronometer from OSD
|
|
|
|
---Purpose: This class measures CPU time (both user and system) consumed
|
|
-- by current process or thread. The chronometer can be started
|
|
-- and stopped multiple times, and measures cumulative time.
|
|
--
|
|
-- If only the thread is measured, calls to Stop() and Show()
|
|
-- must occur from the same thread where Start() was called
|
|
-- (unless chronometer is stopped); otherwise measurement will
|
|
-- yield false values.
|

Create (ThisThreadOnly: Boolean = Standard_False) returns Chronometer from OSD;
|
|
---Purpose: Initializes a stopped Chronometer.
|
|
--
|
|
-- If ThisThreadOnly is True, measured CPU time will account
|
|
-- time of the current thread only; otherwise CPU of the
|
|
-- process (all threads, and completed children) is measured.

GetProcessCPU (myclass; UserSeconds : out Real from Standard;

SystemSeconds : out Real from Standard);
|
|
---Purpose: Returns CPU time (user and system) consumed by the current
|
|
-- process since its start, in seconds. The actual precision of
|
|
-- the measurement depends on granularity provided by the system,
|
|
-- and is platform-specific.

GetThreadCPU (myclass; UserSeconds : out Real from Standard;

SystemSeconds : out Real from Standard);
|
|
---Purpose: Returns CPU time (user and system) consumed by the current
|
|
-- thread since its start. Note that this measurement is
|
|
-- platform-specific, as threads are implemented and managed
|
|
-- differently on different platforms and CPUs.
