Detailed Description

The profiler allows you to measure the performance of your code.

Remarks: Do not create profiles directly from this unless you want a profile to last outside of its scope (i.e. the main game loop). For most cases, use the macro OgreProfile(name) and braces to limit the scope. You must enable the Profile before you can used it with setEnabled(true). If you want to disable profiling in Ogre, simply set the macro OGRE_PROFILING to 0.

Constructor & Destructor Documentation

◆ Profiler()

Ogre::Profiler::Profiler ( )

◆ ~Profiler()

Ogre::Profiler::~Profiler ( )

Member Function Documentation

◆ setTimer()

void Ogre::Profiler::setTimer ( Timer * t )

Sets the timer for the profiler.

◆ getTimer()

Timer* Ogre::Profiler::getTimer ( )

Retrieves the timer for the profiler.

◆ beginProfile()

void Ogre::Profiler::beginProfile	(	const String &	profileName,
		uint32	groupID = `(uint32) OGREPROF_USER_DEFAULT`
	)

Begins a profile.

Remarks: Use the macro OgreProfileBegin(name) instead of calling this directly so that profiling can be ignored in the release version of your app.; You only use the macro (or this) if you want a profile to last outside of its scope (i.e. the main game loop). If you use this function, make sure you use a corresponding OgreProfileEnd(name). Usually you would use the macro OgreProfile(name). This function will be ignored for a profile that has been disabled or if the profiler is disabled.

Parameters

profileName	Must be unique and must not be an empty string
groupID	A profile group identifier, which can allow you to mask profiles

◆ endProfile()

void Ogre::Profiler::endProfile	(	const String &	profileName,
		uint32	groupID = `(uint32) OGREPROF_USER_DEFAULT`
	)

Ends a profile.

Remarks: Use the macro OgreProfileEnd(name) instead of calling this directly so that profiling can be ignored in the release version of your app.; This function is usually not called directly unless you want a profile to last outside of its scope. In most cases, using the macro OgreProfile(name) which will call this function automatically when it goes out of scope. Make sure the name of this profile matches its corresponding beginProfile name. This function will be ignored for a profile that has been disabled or if the profiler is disabled.

Parameters

profileName	Must be unique and must not be an empty string
groupID	A profile group identifier, which can allow you to mask profiles

◆ beginGPUEvent()

void Ogre::Profiler::beginGPUEvent ( const String & event )

Mark the beginning of a GPU event group.

Remarks: Can be safely called in the middle of the profile.

◆ endGPUEvent()

void Ogre::Profiler::endGPUEvent ( const String & event )

Mark the end of a GPU event group.

Remarks: Can be safely called in the middle of the profile.

◆ markGPUEvent()

void Ogre::Profiler::markGPUEvent ( const String & event )

Mark a specific, ungrouped, GPU event.

Remarks: Can be safely called in the middle of the profile.

◆ setEnabled()

void Ogre::Profiler::setEnabled ( bool enabled )

Sets whether this profiler is enabled.

Only takes effect after the the frame has ended.

Remarks: When this is called the first time with the parameter true, it initializes the GUI for the Profiler

◆ getEnabled()

bool Ogre::Profiler::getEnabled ( ) const

Gets whether this profiler is enabled.

◆ enableProfile()

void Ogre::Profiler::enableProfile ( const String & profileName )

Enables a previously disabled profile.

Remarks: Can be safely called in the middle of the profile.

◆ disableProfile()

void Ogre::Profiler::disableProfile ( const String & profileName )

Disables a profile.

Remarks: Can be safely called in the middle of the profile.

◆ setProfileGroupMask()

void Ogre::Profiler::setProfileGroupMask ( uint32 mask )

inline

Set the mask which all profiles must pass to be enabled.

◆ getProfileGroupMask()

uint32 Ogre::Profiler::getProfileGroupMask ( ) const

inline

Get the mask which all profiles must pass to be enabled.

◆ watchForMax()

bool Ogre::Profiler::watchForMax ( const String & profileName )

Returns true if the specified profile reaches a new frame time maximum.

Remarks: If this is called during a frame, it will be reading the results from the previous frame. Therefore, it is best to use this after the frame has ended.

◆ watchForMin()

bool Ogre::Profiler::watchForMin ( const String & profileName )

Returns true if the specified profile reaches a new frame time minimum.

Remarks: If this is called during a frame, it will be reading the results from the previous frame. Therefore, it is best to use this after the frame has ended.

◆ watchForLimit()

bool Ogre::Profiler::watchForLimit	(	const String &	profileName,
		Real	limit,
		bool	greaterThan = `true`
	)

Returns true if the specified profile goes over or under the given limit frame time.

Remarks: If this is called during a frame, it will be reading the results from the previous frame. Therefore, it is best to use this after the frame has ended.

Parameters

limit	A number between 0 and 1 representing the percentage of frame time
greaterThan	If true, this will return whether the limit is exceeded. Otherwise, it will return if the frame time has gone under this limit.

◆ logResults()

void Ogre::Profiler::logResults ( )

Outputs current profile statistics to the log.

◆ reset()

void Ogre::Profiler::reset ( )

Clears the profiler statistics.

◆ setUpdateDisplayFrequency()

void Ogre::Profiler::setUpdateDisplayFrequency ( uint freq )

Sets the Profiler so the display of results are updated every n frames.

◆ getUpdateDisplayFrequency()

uint Ogre::Profiler::getUpdateDisplayFrequency ( ) const

Gets the frequency that the Profiler display is updated.

◆ addListener()

void Ogre::Profiler::addListener ( ProfileSessionListener * listener )

Remarks: Register a ProfileSessionListener from the Profiler

Parameters

listener A valid listener derived class

◆ removeListener()

void Ogre::Profiler::removeListener ( ProfileSessionListener * listener )

Remarks: Unregister a ProfileSessionListener from the Profiler

Parameters

listener A valid listener derived class

◆ getSingleton()

static Profiler& Ogre::Profiler::getSingleton ( void )

static

Get the singleton instance.

◆ getSingletonPtr()

static Profiler* Ogre::Profiler::getSingletonPtr ( void )

static

Get the singleton instance.
