#include <AdvancedTimer.h>

Detailed Description

Advanced timer, meant to gather precise statistics for results in published papers. Not so advanced for now, but it will be...

Usage examples :

When all computations start (i.e., Simulation::step): AdvancedTimer::begin("Animate");

When all computations stop (i.e., Simulation::step): AdvancedTimer::end("Animate");

Using a local variable to automatically call end when current instruction block (i.e. method) ends : AdvancedTimer::TimerVar("Animate");

When a part of the computation starts: AdvancedTimer::stepBegin("Collision");

When a part of the computation stops: AdvancedTimer::stepEnd("Collision");

Both operations combined: AdvancedTimer::stepNext("Collision", "Mechanical");

Using a local variable to automatically call stepEnd when current instruction block (i.e. method) ends : AdvancedTimer::StepVar("UpdateMapping");

Specifying the object being processed: AdvancedTimer::StepVar("Collision", objPtr);

When a noteworthy milestone happens: AdvancedTimer::step("Event1");

When a noteworthy value must be stored: AdvancedTimer::valSet("contacts",nbContacts);

When a noteworthy value must be accumulated: AdvancedTimer::valAdd("dofs",mstate->getSize());

When reloading/reseting the simulation: AdvancedTimer::clear();

The produced stats will looks like:

==== Animate ====

Trace of last iteration : 0 ms > begin Collision : var nbCM = 10 10 ms > begin BP 20 ms < end NP > begin NP 120 ms < end NP : var nbContacts = 100 > begin Response 150 ms < end Response < end Collision > begin Mechanical > begin CGSolve on Torus1 : var dofs += 300 ... 434 ms END
