Detailed Description

Basic wall-clock timer class.

To time a section of code, place it in between calls to start() and stop().

Note:

For exception safety and correct behavior in reentrant code, this class should generally be used only through the Teuchos::TimeMonitor mechanism.

Member Function Documentation

double Time::wallTime (   )  [static]

Returns current wall-clock time in seconds. Definition at line 72 of file Teuchos_Time.cpp.

void Time::start (  bool  reset = false  )

Starts the timer. Definition at line 54 of file Teuchos_Time.cpp.

double Time::stop (   )

Stops the timer. Definition at line 61 of file Teuchos_Time.cpp.

double Teuchos::Time::totalElapsedTime (   )  const [inline]

Returns the total time accumulated by this timer. This should be called only when the clock is stopped.. Definition at line 83 of file Teuchos_Time.hpp.

bool Teuchos::Time::isRunning (   )  const [inline]

Indicates if this timer is currently running, i.e., if it has been started but not yet stopped. It is necessary to know if a timer is running to avoid incorrectly starting or stopping in reentrant code. Definition at line 90 of file Teuchos_Time.hpp.

const string& Teuchos::Time::name (   )  const [inline]

Return the name of this timer. Definition at line 93 of file Teuchos_Time.hpp.
