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 Teuchos::Time::wallTime (   )  [static]

Returns current wall-clock time in seconds. Definition at line 96 of file Teuchos_Time.cpp.

void Teuchos::Time::start (  bool  reset = false  )

Starts the timer. Definition at line 71 of file Teuchos_Time.cpp.

double Teuchos::Time::stop (   )

Stops the timer. Definition at line 78 of file Teuchos_Time.cpp.

double Teuchos::Time::totalElapsedTime (  bool  readCurrentTime = false  )  const

Returns the total time accumulated by this timer. This should be called only when the clock is stopped.. Definition at line 88 of file Teuchos_Time.cpp.

void Teuchos::Time::reset (   )  [inline]

Resets the cummulative time and number of times this timer has been called. Does not affect any other state. Definition at line 99 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 106 of file Teuchos_Time.hpp.

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

Return the name of this timer. Definition at line 109 of file Teuchos_Time.hpp.

void Teuchos::Time::incrementNumCalls (   )  [inline]

Increment the number of times this timer has been called. Definition at line 112 of file Teuchos_Time.hpp.

int Teuchos::Time::numCalls (   )  const [inline]

Return the number of times this timer has been called. Definition at line 115 of file Teuchos_Time.hpp.
