class QgsRuntimeProfiler : QAbstractItemModel
{
%Docstring(signature="appended")

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

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

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

%TypeHeaderCode
#include "qgsruntimeprofiler.h"
%End
  public:

    QgsRuntimeProfiler();
%Docstring
Constructor to create a new runtime profiler.

.. warning::

   QgsRuntimeProfiler is not usually instantied manually, but rather accessed
   through :py:func:`QgsApplication.profiler()`.
%End
    ~QgsRuntimeProfiler();

 void beginGroup( const QString &name ) /Deprecated/;
%Docstring
Begin the group for the profiler. Groups will append {GroupName}/ to the
front of the profile tag set using start.

:param name: The name of the group.

.. deprecated::
   use :py:func:`~QgsRuntimeProfiler.start` instead
%End

 void endGroup() /Deprecated/;
%Docstring
End the current active group.

.. deprecated::
   use :py:func:`~QgsRuntimeProfiler.end` instead
%End

    QStringList childGroups( const QString &parent = QString(), const QString &group = "startup" ) const;
%Docstring
Returns a list of all child groups with the specified ``parent``.

.. versionadded:: 3.14
%End

    void start( const QString &name, const QString &group = "startup" );
%Docstring
Start a profile event with the given name.
The ``name`` of the profile event. Will have the name of
the active ``group`` appended after ending.
%End

    void end( const QString &group = "startup" );
%Docstring
End the current profile event.
%End

    double profileTime( const QString &name, const QString &group = "startup" ) const;
%Docstring
Returns the profile time for the specified ``name``.

.. versionadded:: 3.14
%End

    void clear( const QString &group = "startup" );
%Docstring
clear Clear all profile data.
%End

    double totalTime( const QString &group = "startup" );
%Docstring
The current total time collected in the profiler.

:return: The current total time collected in the profiler.
%End

    QSet< QString > groups() const;
%Docstring
Returns the set of known groups.
%End

    bool groupIsActive( const QString &group ) const;
%Docstring
Returns ``True`` if the specified ``group`` is currently being logged,
i.e. it has a entry which has started and not yet stopped.

.. versionadded:: 3.14
%End

    static QString translateGroupName( const QString &group );
%Docstring
Returns the translated name of a standard profile ``group``.

Emitted when a new group has started being profiled.

class QgsScopedRuntimeProfile
{
%Docstring(signature="appended")

Scoped object for logging of the runtime for a single operation or group of operations.

This class automatically takes care of registering an operation in the :py:func:`QgsApplication.profiler()`
registry upon construction, and recording of the elapsed runtime upon destruction.

Python scripts should not use :py:class:`QgsScopedRuntimeProfile` directly. Instead, use :py:func:`QgsRuntimeProfiler.profile()`
.. code-block:: python

       with QgsRuntimeProfiler.profile('My operation'):
         # do something

.. versionadded:: 3.14
%End

%TypeHeaderCode
#include "qgsruntimeprofiler.h"
%End
  public:

    QgsScopedRuntimeProfile( const QString &name, const QString &group = "startup" );
%Docstring
Constructor for QgsScopedRuntimeProfile.

Automatically registers the operation in the :py:func:`QgsApplication.profiler()` instance
and starts recording the run time of the operation.
%End

    ~QgsScopedRuntimeProfile();

    void switchTask( const QString &name );
%Docstring
Switches the current task managed by the scoped profile to a new task with the given ``name``.
The current task will be finalised before switching.

This is useful for reusing an existing scoped runtime profiler with multi-step processes.

.. versionadded:: 3.14
%End
