ExportFLAC()

ExportFLAC::ExportFLAC ( )

default

Member Function Documentation

CreateOptionsEditor()

std::unique_ptr< ExportOptionsEditor > ExportFLAC::CreateOptionsEditor ( int  formatIndex, ExportOptionsEditor::Listener *  listener  ) const

overridevirtual

Creates format-dependent options editor, that is used to create a valid set of parameters to be used in exporting.

Parameters

listener

Option listener object that could be used by the editor to report on option changes.

Implements ExportPlugin.

Definition at line 282 of file ExportFLAC.cpp.

{
   return std::make_unique<PlainExportOptionsEditor>(FlacOptions, listener);
}

References anonymous_namespace{ExportFLAC.cpp}::FlacOptions.

CreateProcessor()

std::unique_ptr< ExportProcessor > ExportFLAC::CreateProcessor ( int  format ) const

overridevirtual

Parameters

format

Control which of the multiple formats this exporter is capable of exporting should be used. Used where a single export plug-in handles a number of related formats, but they have separate entries in the Format drop-down list box. For example, the options to export to "Other PCM", "AIFF 16 Bit" and "WAV 16 Bit" are all the same libsndfile export plug-in, but with subformat set to 0, 1, and 2 respectively.

Implements ExportPlugin.

   return std::make_unique<FLACExportProcessor>();

GetFormatCount()

int ExportFLAC::GetFormatCount ( ) const

overridevirtual

Implements ExportPlugin.

Definition at line 232 of file ExportFLAC.cpp.

{
   return 1;
}

GetFormatInfo()

FormatInfo ExportFLAC::GetFormatInfo ( int  index ) const

overridevirtual

Returns FormatInfo structure for given index if it's valid, or a default one. FormatInfo::format isn't guaranteed to be unique.

Parameters

index

Should not exceed the number of formats provided by GetFormatCount()

Implements ExportPlugin.

GetMimeTypes()

std::vector< std::string > ExportFLAC::GetMimeTypes ( int  formatIndex ) const

overridevirtual

Returns

Mime type(s) supported by the format.

}

ParseConfig()

bool ExportFLAC::ParseConfig ( int  formatIndex, const rapidjson::Value &  config, ExportProcessor::Parameters &  parameters  ) const
