Detailed Description

An implementation of Ogg::File with Opus specific methods.

This is the central class in the Ogg Opus metadata processing collection of classes. It's built upon Ogg::File which handles processing of the Ogg logical bitstream and breaking it down into pages which are handled by the codec implementations, in this case Opus specifically.

Constructor & Destructor Documentation

File() [1/3]

TagLib::Ogg::Opus::File::File	(	FileName	file,
		bool	readProperties = true,
		Properties::ReadStyle	propertiesStyle = Properties::Average
	)

Constructs an Opus file from file. If readProperties is true the file's audio properties will also be read.

Note

In the current implementation, propertiesStyle is ignored.

File() [2/3]

TagLib::Ogg::Opus::File::File	(	IOStream *	stream,
		bool	readProperties = true,
		Properties::ReadStyle	propertiesStyle = Properties::Average
	)

Constructs an Opus file from stream. If readProperties is true the file's audio properties will also be read.

Note

TagLib will not take ownership of the stream, the caller is responsible for deleting it after the File object.

In the current implementation, propertiesStyle is ignored.

~File()

TagLib::Ogg::Opus::File::~File ( )

overridevirtual

Destroys this instance of the File.

Reimplemented from TagLib::Ogg::File.

File() [3/3]

TagLib::Ogg::Opus::File::File ( const File &  )

delete

Member Function Documentation

audioProperties()

Properties * TagLib::Ogg::Opus::File::audioProperties ( ) const

overridevirtual

Returns the Opus::Properties for this file. If no audio properties were read then this will return a null pointer.

Implements TagLib::File.

isSupported()

static bool TagLib::Ogg::Opus::File::isSupported ( IOStream *  stream )

static

Returns whether or not the given stream can be opened as an Opus file.

Note

This method is designed to do a quick check. The result may not necessarily be correct.

operator=()

File & TagLib::Ogg::Opus::File::operator= ( const File &  )

delete

properties()

PropertyMap TagLib::Ogg::Opus::File::properties ( ) const

overridevirtual

Implements the unified property interface – export function. This forwards directly to XiphComment::properties().

Reimplemented from TagLib::File.

save()

bool TagLib::Ogg::Opus::File::save ( )

overridevirtual

Save the file.

This returns true if the save was successful.

Reimplemented from TagLib::Ogg::File.

setProperties()

PropertyMap TagLib::Ogg::Opus::File::setProperties ( const PropertyMap &  )

overridevirtual

Implements the unified tag dictionary interface – import function. Like properties(), this is a forwarder to the file's XiphComment.

Reimplemented from TagLib::File.

tag()

Ogg::XiphComment * TagLib::Ogg::Opus::File::tag ( ) const

overridevirtual

Returns the XiphComment for this file. XiphComment implements the tag interface, so this serves as the reimplementation of TagLib::File::tag().

Implements TagLib::File.
