Detailed Description

An implementation of TagLib::File with Matroska specific methods.

Implementation of TagLib::File for Matroska.

Constructor & Destructor Documentation

File() [1/3]

TagLib::Matroska::File::File ( FileName  file, bool  readProperties = true, Properties::ReadStyle  readStyle = Properties::Average  )

explicit

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

If readStyle is Accurate all seek head and cues segment positions are verified for the isValid() state of the file.

File() [2/3]

TagLib::Matroska::File::File ( IOStream *  stream, bool  readProperties = true, Properties::ReadStyle  readStyle = Properties::Average  )

explicit

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

If readStyle is Accurate all seek head and cues segment positions are verified for the isValid() state of the file.

~File()

TagLib::Matroska::File::~File ( )

overridevirtual

Destroys this instance of the File.

Reimplemented from TagLib::File.

File() [3/3]

TagLib::Matroska::File::File ( const File &  )

delete

Member Function Documentation

attachments()

Attachments* TagLib::Matroska::File::attachments

(

bool

create = false

)

const

Returns a pointer to the attachments of the file.

If create is false this may return a null pointer if there are no attachments. If create is true it will create attachments if none exist and returns a valid pointer.

audioProperties()

Properties* TagLib::Matroska::File::audioProperties ( ) const

overridevirtual

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

Implements TagLib::File.

chapters()

Chapters* TagLib::Matroska::File::chapters

(

bool

create = false

)

const

Returns a pointer to the chapters of the file.

If create is false this may return a null pointer if there are no chapters. If create is true it will create chapters if none exist and returns a valid pointer.

complexProperties()

List<VariantMap> TagLib::Matroska::File::complexProperties ( const String &  key ) const

overridevirtual

Get the pictures stored in the attachments as complex properties for key "PICTURE". Other attached files can be retrieved, by media type, file name or UID. The attached files are returned as maps with keys "data", "mimeType", "description", "fileName, "uid". Binary simple tags can be retrieved as maps with keys "data", "name", "targetTypeValue", "language", "defaultLanguage".

Reimplemented from TagLib::File.

complexPropertyKeys()

StringList TagLib::Matroska::File::complexPropertyKeys ( ) const

overridevirtual

Returns the keys for attached files, "PICTURE" for images, the media type, file name or UID for other attached files. The names of the binary simple tags are included too.

Reimplemented from TagLib::File.

isSupported()

static bool TagLib::Matroska::File::isSupported ( IOStream *  stream )

static

Returns whether or not the given stream can be opened as a Matroska file.

Note

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

operator=()

File& TagLib::Matroska::File::operator= ( const File &  )

delete

properties()

PropertyMap TagLib::Matroska::File::properties ( ) const

overridevirtual

Implements the reading part of the unified property interface.

Reimplemented from TagLib::File.

removeUnsupportedProperties()

void TagLib::Matroska::File::removeUnsupportedProperties ( const StringList &  properties )

overridevirtual

Removes unsupported properties, or a subset of them, from the file's metadata. The parameter properties must contain only entries from properties().unsupportedData().

Reimplemented from TagLib::File.

save()

bool TagLib::Matroska::File::save ( )

overridevirtual

Save the file.

This returns true if the save was successful.

Implements TagLib::File.

setComplexProperties()

bool TagLib::Matroska::File::setComplexProperties ( const String &  key, const List< VariantMap > &  value  )

overridevirtual

Set attached files as complex properties value, e.g. pictures for key "PICTURE" with the maps in value having keys "data", "mimeType", "description", "fileName, "uid". For other attached files, the mime type, file name or UID can be used as the key. Maps with keys "name" (with the same value as key) and "data" are stored as binary simple tags with additional keys "targetTypeValue", "language", "defaultLanguage".

Reimplemented from TagLib::File.

setProperties()

PropertyMap TagLib::Matroska::File::setProperties ( const PropertyMap &  )

overridevirtual

Implements the writing part of the unified tag dictionary interface.

Reimplemented from TagLib::File.

tag() [1/2]

TagLib::Tag* TagLib::Matroska::File::tag ( ) const

overridevirtual

Returns a pointer to the tag of the file.

It will create a tag if one does not exist and returns a valid pointer.

Note

The tag is still owned by the Matroska::File and should not be deleted by the user. It will be deleted when the file (object) is destroyed.

Implements TagLib::File.

tag() [2/2]

Tag* TagLib::Matroska::File::tag

(

bool

create

)

const

Returns a pointer to the Matroska tag of the file.

If create is false this may return a null pointer if there is no tag. If create is true it will create a tag if one does not exist and returns a valid pointer.

Note

The tag is still owned by the Matroska::File and should not be deleted by the user. It will be deleted when the file (object) destroyed.
