class QgsApplication
 

Detailed Description

Provides a method of recording run time profiles of operations, allowing easy recording of their overall run time.

QgsRuntimeProfiler is not usually instantied manually, but rather accessed through QgsApplication::profiler().

This class is thread-safe only if accessed through QgsApplication::profiler(). If accessed in this way, operations can be profiled from non-main threads.

Member Function Documentation

◆ beginGroup()

void QgsRuntimeProfiler::beginGroup ( const QString &  name)

Begin the group for the profiler.

Groups will append {GroupName}/ to the front of the profile tag set using start.

Parameters
nameThe name of the group.
Deprecated:
use start() instead

Definition at line 179 of file qgsruntimeprofiler.cpp.

◆ childGroups()

QStringList QgsRuntimeProfiler::childGroups ( const QString &  parent = QString(),
const QString &  group = "startup" 
) const

Returns a list of all child groups with the specified parent.

Since
QGIS 3.14

Definition at line 189 of file qgsruntimeprofiler.cpp.

◆ clear()

void QgsRuntimeProfiler::clear ( const QString &  group = "startup")

clear Clear all profile data.

Definition at line 273 of file qgsruntimeprofiler.cpp.

◆ columnCount()

int QgsRuntimeProfiler::columnCount ( const QModelIndex &  parent = QModelIndex()) const
override

Definition at line 319 of file qgsruntimeprofiler.cpp.

QVariant QgsRuntimeProfiler::data ( const QModelIndex &  index,
int  role = Qt::DisplayRole 
) const
override

Definition at line 354 of file qgsruntimeprofiler.cpp.

◆ end()

void QgsRuntimeProfiler::end ( const QString &  group = "startup")

End the current profile event.

Definition at line 238 of file qgsruntimeprofiler.cpp.

◆ endGroup()

void QgsRuntimeProfiler::endGroup ( )

End the current active group.

Deprecated:
use end() instead

Definition at line 184 of file qgsruntimeprofiler.cpp.

◆ groupAdded()

void QgsRuntimeProfiler::groupAdded ( const QString &  group)

Emitted when a new group has started being profiled.

◆ groupIsActive()

bool QgsRuntimeProfiler::groupIsActive ( const QString &  group) const

Returns true if the specified group is currently being logged, i.e.

it has a entry which has started and not yet stopped.

Since

◆ start()

void QgsRuntimeProfiler::start ( const QString &  name,
const QString &  group = "startup" 
)

Start a profile event with the given name.

Parameters
nameThe name of the profile event. Will have the name of the active group appended after ending.

Definition at line 206 of file qgsruntimeprofiler.cpp.

◆ totalTime()

double QgsRuntimeProfiler::totalTime ( const QString &  group = "startup")

The current total time collected in the profiler.
