Detailed Description

Implement this interface and register your Exporter to the ExporterRegistry instance in the main routine to make an Exporter available.

Member Enumeration Documentation

Type

enum ExporterInterface::Type

strong

Exporters can save only a single sample set or save data continuously.

Constructor & Destructor Documentation

~ExporterInterface()

ExporterInterface::~ExporterInterface ( )

virtual

Member Function Documentation

create()

virtual void ExporterInterface::create ( ExporterRegistry *  registry )

pure virtual

Starts up this exporter. Aquires resources etc. Do not call this directly, it will be called by the exporter registry at some point. Release your resources in the destructor as usual.

Parameters

registry

The exporter registry instance. This is used to obtain a reference to the settings.

Implemented in ExporterJSON, and ExporterCSV.

faIcon()

virtual int ExporterInterface::faIcon ( )

pure virtual

Returns

Return the icon representation of this exporter. Will be used in graphical interfaces.

Implemented in ExporterJSON, and ExporterCSV.

name()

virtual QString ExporterInterface::name ( )

pure virtual

Returns

Return the text representation / name of this exporter. Will be used in graphical interfaces.

Implemented in ExporterJSON, and ExporterCSV.

progress()

virtual float ExporterInterface::progress ( )

pure virtual

The progress of receiving and processing samples. If the exporter returns 1, it will be called back by the GUI via the save() method.

Returns

A number between 0..1 indicating the used capacity of this exporter. If this is a snapshot exporter, only 0 for "no samples processed yet" or 1 for "finished" will be returned. A continuous exporter may report the used memory / reservered memory ratio here.

Implemented in ExporterJSON, and ExporterCSV.

samples()

virtual bool ExporterInterface::samples ( const std::shared_ptr< PPresult >  )

pure virtual

A new sample set from the ExporterRegistry. The exporter needs to be active to receive samples. If it is a snapshot exporter, only one set of samples will be received.

Returns

Return true if you want to receive another sample or false if you are done (progres()==1).

Implemented in ExporterJSON, and ExporterCSV.

save()

virtual bool ExporterInterface::save ( )

pure virtual

Exporter: Save your received data and perform any conversions necessary. This method will be called in the GUI thread context and can create and show dialogs if required.

Returns

Return true if saving succedded otherwise false.

Implemented in ExporterJSON, and ExporterCSV.

type()

virtual Type ExporterInterface::type ( )

pure virtual

Returns

Return the type of this exporter.
