Member Function Documentation

◆ dumpJSON()

void Arcane::ProfPerformanceService::dumpJSON ( JSONWriter & writer )

overridevirtual

Writes the profiling information to the writer writer.

Implements Arcane::IProfilingService.

Definition at line 292 of file ProfPerformanceService.cc.

◆ getInfos()

void Arcane::ProfPerformanceService::getInfos ( Int64Array & )

overridevirtual

Implements Arcane::IProfilingService.

Definition at line 302 of file ProfPerformanceService.cc.

◆ initialize()

void Arcane::ProfPerformanceService::initialize ( )

overridevirtual

Initializes the profiling service.

This method can only be called once.

Implements Arcane::IProfilingService.

Definition at line 215 of file ProfPerformanceService.cc.

References Arcane::TraceAccessor::traceMng().

Here is the call graph for this function:

◆ isInitialized()

bool Arcane::ProfPerformanceService::isInitialized ( ) const

inlineoverridevirtual

Indicates if initialize() has already been called.

Reimplemented from Arcane::IProfilingService.

Definition at line 62 of file ProfPerformanceService.cc.

◆ isRunning()

bool Arcane::ProfPerformanceService::isRunning ( ) const

overridevirtual

Indicates if the profiling is running.

The profiling is running between a call to startProfiling() and stopProfiling().

Implements Arcane::IProfilingService.

Definition at line 321 of file ProfPerformanceService.cc.

◆ printInfos()

void Arcane::ProfPerformanceService::printInfos ( bool dump_file )

overridevirtual

Displays profiling information.

Profiling must be stopped. If dump_file is true, file outputs containing the information are generated, which may take time.

Implements Arcane::IProfilingService.

Definition at line 282 of file ProfPerformanceService.cc.

◆ reset()

void Arcane::ProfPerformanceService::reset ( )

overridevirtual

Resets the counters.

Profiling must be stopped for this.

Implements Arcane::IProfilingService.

Definition at line 311 of file ProfPerformanceService.cc.

◆ startProfiling()

void Arcane::ProfPerformanceService::startProfiling ( )

overridevirtual

Starts profiling.

Implements Arcane::IProfilingService.

Definition at line 231 of file ProfPerformanceService.cc.

References ARCANE_FATAL.

◆ stopProfiling()

void Arcane::ProfPerformanceService::stopProfiling ( )

overridevirtual

Stops profiling.

Implements Arcane::IProfilingService.

Definition at line 259 of file ProfPerformanceService.cc.

◆ switchEvent()

void Arcane::ProfPerformanceService::switchEvent ( )

overridevirtual

Implements Arcane::IProfilingService.

Definition at line 251 of file ProfPerformanceService.cc.

◆ timerMng()

ITimerMng * Arcane::ProfPerformanceService::timerMng ( )

inlineoverridevirtual

Timer using the features of this service if they exist. Can be null.

Implements Arcane::IProfilingService.

Definition at line 71 of file ProfPerformanceService.cc.
