Constructor & Destructor Documentation

◆ QgsRuntimeProfilerNode() [1/2]

QgsRuntimeProfilerNode::QgsRuntimeProfilerNode	(	const QString &	group,
		const QString &	name,
		const QString &	id = `QString()`
	)

Constructor for QgsRuntimeProfilerNode, with the specified group and name.

Since QGIS 3.34 an internal id can be specified to disambiguate entries with duplicate names.

Definition at line 30 of file qgsruntimeprofiler.cpp.

◆ QgsRuntimeProfilerNode() [2/2]

QgsRuntimeProfilerNode::QgsRuntimeProfilerNode ( const QgsRuntimeProfilerNode & other )

delete

◆ ~QgsRuntimeProfilerNode()

QgsRuntimeProfilerNode::~QgsRuntimeProfilerNode ( )

default

Member Function Documentation

◆ addChild()

void QgsRuntimeProfilerNode::addChild ( std::unique_ptr< QgsRuntimeProfilerNode > child )

Adds a child node to this node.

Definition at line 80 of file qgsruntimeprofiler.cpp.

◆ child()

QgsRuntimeProfilerNode * QgsRuntimeProfilerNode::child	(	const QString &	group,
		const QString &	name,
		const QString &	id = `QString()`
	)

Finds the child with matching group, name and id (since QGIS 3.34).

Returns nullptr if a matching child was not found.

Definition at line 103 of file qgsruntimeprofiler.cpp.

◆ childAt()

QgsRuntimeProfilerNode * QgsRuntimeProfilerNode::childAt ( int index )

Returns the child at the specified index.

Definition at line 115 of file qgsruntimeprofiler.cpp.

◆ childCount()

int QgsRuntimeProfilerNode::childCount ( ) const

inline

Returns the number of child nodes owned by this node.

Definition at line 95 of file qgsruntimeprofiler.h.

◆ clear()

void QgsRuntimeProfilerNode::clear ( )

Clears the node, removing all its children.

Definition at line 121 of file qgsruntimeprofiler.cpp.

◆ data()

QVariant QgsRuntimeProfilerNode::data ( int role = Qt::DisplayRole ) const

Returns the node's data for the specified model role.

Definition at line 56 of file qgsruntimeprofiler.cpp.

◆ elapsed()

double QgsRuntimeProfilerNode::elapsed ( ) const

Returns the node's elapsed time, in seconds.

If the node is still running then 0 will be returned.

Definition at line 147 of file qgsruntimeprofiler.cpp.

◆ fullParentPath()

QStringList QgsRuntimeProfilerNode::fullParentPath ( ) const

Returns the full path to the node's parent.

This will contain node IDs if set, otherwise node names.

Definition at line 40 of file qgsruntimeprofiler.cpp.

◆ indexOf()

int QgsRuntimeProfilerNode::indexOf ( QgsRuntimeProfilerNode * child ) const

Returns the index of the specified child node.

Warning: child must be a valid child of this node.

Definition at line 91 of file qgsruntimeprofiler.cpp.

◆ operator=()

QgsRuntimeProfilerNode & QgsRuntimeProfilerNode::operator= ( const QgsRuntimeProfilerNode & other )

delete

◆ parent()

QgsRuntimeProfilerNode * QgsRuntimeProfilerNode::parent ( )

inline

Returns the node's parent node.

If parent is nullptr, the node is a root node

Definition at line 78 of file qgsruntimeprofiler.h.

◆ removeChildAt()

void QgsRuntimeProfilerNode::removeChildAt ( int index )

Removes and deletes the child at the specified index.

Definition at line 126 of file qgsruntimeprofiler.cpp.

◆ setElapsed()

void QgsRuntimeProfilerNode::setElapsed ( double time )

Manually sets the node's elapsed time, in seconds.

Definition at line 142 of file qgsruntimeprofiler.cpp.

◆ start()

void QgsRuntimeProfilerNode::start ( )

Starts the node timer.

See also: stop()

Definition at line 132 of file qgsruntimeprofiler.cpp.

◆ stop()

void QgsRuntimeProfilerNode::stop ( )

Stops the node's timer, recording the elapsed time automatically.

Definition at line 137 of file qgsruntimeprofiler.cpp.

◆ totalElapsedTimeForChildren()

double QgsRuntimeProfilerNode::totalElapsedTimeForChildren ( const QString & group ) const

Returns the total elapsed time in seconds for all children of this node with matching group.

Definition at line 152 of file qgsruntimeprofiler.cpp.
