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.

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

Parameters

name	The 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.

void QgsRuntimeProfiler::groupAdded ( const QString & group )

Emitted when a new group has started being profiled.

◆ groupIsActive()

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