Detailed Description

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

This implements and provides an interface for FLAC files to the TagLib::Tag and TagLib::AudioProperties interfaces by way of implementing the abstract TagLib::File API as well as providing some additional information specific to FLAC files.


Member Enumeration Documentation

This set of flags is used for various operations and is suitable for being OR-ed together.

Enumerator:
NoTags 

Empty set. Matches no tag types.

XiphComment 

Matches Vorbis comments.

ID3v1 

Matches ID3v1 tags.

ID3v2 

Matches ID3v2 tags.

AllTags 

Matches all tag types.


Constructor & Destructor Documentation

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

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

Note:
In the current implementation, propertiesStyle is ignored.
TagLib::FLAC::File::File ( FileName  file,
ID3v2::FrameFactory frameFactory,
bool  readProperties = true,
Properties::ReadStyle  propertiesStyle = Properties::Average 
)

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

If this file contains and ID3v2 tag the frames will be created using frameFactory.

Note:
In the current implementation, propertiesStyle is ignored.
TagLib::FLAC::File::File ( IOStream stream,
ID3v2::FrameFactory frameFactory,
bool  readProperties = true,
Properties::ReadStyle  propertiesStyle = Properties::Average 
)

Constructs a FLAC 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.

If this file contains and ID3v2 tag the frames will be created using frameFactory.

Note:
In the current implementation, propertiesStyle is ignored.
virtual TagLib::FLAC::File::~File ( ) [virtual]

Destroys this instance of the File.

Reimplemented from TagLib::File.


Member Function Documentation

Add a new picture to the file. The file takes ownership of the picture and will handle freeing its memory.

Note:
The file will be saved only after calling save().
virtual Properties* TagLib::FLAC::File::audioProperties ( ) const [virtual]

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

Implements TagLib::File.

Returns whether or not the file on disk actually has an ID3v1 tag.

See also:
ID3v1Tag()

Returns whether or not the file on disk actually has an ID3v2 tag.

See also:
ID3v2Tag()

Returns whether or not the file on disk actually has a XiphComment.

See also:
xiphComment()
ID3v1::Tag* TagLib::FLAC::File::ID3v1Tag ( bool  create = false)

Returns a pointer to the ID3v1 tag of the file.

If create is false (the default) this returns a null pointer if there is no valid APE tag. If create is true it will create an APE tag if one does not exist and returns a valid pointer.

Note:
This may return a valid pointer regardless of whether or not the file on disk has an ID3v1 tag. Use hasID3v1Tag() to check if the file on disk actually has an ID3v1 tag.
The Tag is still owned by the MPEG::File and should not be deleted by the user. It will be deleted when the file (object) is destroyed.
See also:
hasID3v1Tag()
ID3v2::Tag* TagLib::FLAC::File::ID3v2Tag ( bool  create = false)

Returns a pointer to the ID3v2 tag of the file.

If create is false (the default) this returns a null pointer if there is no valid ID3v2 tag. If create is true it will create an ID3v2 tag if one does not exist and returns a valid pointer.

Note:
This may return a valid pointer regardless of whether or not the file on disk has an ID3v2 tag. Use hasID3v2Tag() to check if the file on disk actually has an ID3v2 tag.
The Tag is still owned by the MPEG::File and should not be deleted by the user. It will be deleted when the file (object) is destroyed.
See also:
hasID3v2Tag()

Returns a list of pictures attached to the FLAC file.

Implements the unified property interface -- export function. If the file contains more than one tag (e.g. XiphComment and ID3v1), only the first one (in the order XiphComment, ID3v2, ID3v1) will be converted to the PropertyMap.

Reimplemented from TagLib::File.

void TagLib::FLAC::File::removePicture ( Picture picture,
bool  del = true 
)

Removes an attached picture. If del is true the picture's memory will be freed; if it is false, it must be deleted by the user.

Remove all attached images.

Removes unsupported properties, or a subset of them, from the file's metadata. The parameter properties must contain only entries from properties().unsupportedData(). BIC: Will be mad virtual in future releases.

Reimplemented from TagLib::File.

virtual bool TagLib::FLAC::File::save ( ) [virtual]

Save the file. This will primarily save the XiphComment, but will also keep any old ID3-tags up to date. If the file has no XiphComment, one will be constructed from the ID3-tags.

This returns true if the save was successful.

Implements TagLib::File.

Set the ID3v2::FrameFactory to something other than the default. This can be used to specify the way that ID3v2 frames will be interpreted when

See also:
ID3v2FrameFactory

Implements the unified property interface -- import function. This always creates a Xiph comment, if none exists. The return value relates to the Xiph comment only. Ignores any changes to ID3v1 or ID3v2 comments since they are not allowed in the FLAC specification.

Reimplemented from TagLib::File.

Returns the block of data used by FLAC::Properties for parsing the stream properties.

Returns the length of the audio-stream, used by FLAC::Properties for calculating the bitrate.

void TagLib::FLAC::File::strip ( int  tags = AllTags)

This will remove the tags that match the OR-ed together TagTypes from the file. By default it removes all tags.

Warning:
This will also invalidate pointers to the tags as their memory will be freed.
Note:
In order to make the removal permanent save() still needs to be called.
This won't remove the Vorbis comment block completely. The vendor ID will be preserved.
virtual TagLib::Tag* TagLib::FLAC::File::tag ( ) const [virtual]

Returns the Tag for this file. This will be a union of XiphComment, ID3v1 and ID3v2 tags.

See also:
ID3v2Tag()
ID3v1Tag()
XiphComment()

Implements TagLib::File.

Returns a pointer to the XiphComment for the file.

If create is false (the default) this returns a null pointer if there is no valid XiphComment. If create is true it will create a XiphComment if one does not exist and returns a valid pointer.

Note:
This may return a valid pointer regardless of whether or not the file on disk has a XiphComment. Use hasXiphComment() to check if the file on disk actually has a XiphComment.
The Tag is still owned by the FLAC::File and should not be deleted by the user. It will be deleted when the file (object) is destroyed.
