Detailed Description

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

This implements and provides an interface for WavPack 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 WavPack files.

Member Enumeration Documentation

TagTypes

enum TagLib::WavPack::File::TagTypes

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.
ID3v1	Matches ID3v1 tags.
APE	Matches APE tags.
AllTags	Matches all tag types.

Constructor & Destructor Documentation

File() [1/3]

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

Constructs a WavPack file from file. If readProperties is true the file's audio properties will also be read using propertiesStyle. If false, propertiesStyle is ignored

File() [2/3]

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

Constructs a WavPack file from file. If readProperties is true the file's audio properties will also be read using propertiesStyle. If false, propertiesStyle is ignored.

Note

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

~File()

TagLib::WavPack::File::~File ( )

overridevirtual

Destroys this instance of the File.

Reimplemented from TagLib::File.

File() [3/3]

TagLib::WavPack::File::File ( const File &  )

delete

Member Function Documentation

APETag()

APE::Tag * TagLib::WavPack::File::APETag

(

bool

create = false

)

Returns a pointer to the APE tag of the file.

If create is false (the default) this may return 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 APE tag. Use hasAPETag() to check if the file on disk actually has an APE tag.

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

See also

hasAPETag()

audioProperties()

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

overridevirtual

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

Implements TagLib::File.

hasAPETag()

bool TagLib::WavPack::File::hasAPETag

(

)

const

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

See also

APETag()

hasID3v1Tag()

bool TagLib::WavPack::File::hasID3v1Tag

(

)

const

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

See also

ID3v1Tag()

ID3v1Tag()

ID3v1::Tag * TagLib::WavPack::File::ID3v1Tag

(

bool

create = false

)

Returns a pointer to the ID3v1 tag of the file.

If create is false (the default) this may return a null pointer if there is no valid ID3v1 tag. If create is true it will create an ID3v1 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 WavPack::File and should not be deleted by the user. It will be deleted when the file (object) is destroyed.

See also

hasID3v1Tag()

isSupported()

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

static

Check if the given stream can be opened as a WavPack file.

Note

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

operator=()

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

delete

properties()

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

overridevirtual

Implements the unified property interface – export function. If the file contains both an APE and an ID3v1 tag, only APE will be converted to the PropertyMap.

Reimplemented from TagLib::File.

removeUnsupportedProperties()

void TagLib::WavPack::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::WavPack::File::save ( )

overridevirtual

Saves the file.

This returns true if the save was successful.

Implements TagLib::File.

setProperties()

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

overridevirtual

Implements the unified property interface – import function. Creates an APE tag if it does not exists and calls setProperties() on that. Any existing ID3v1 tag will be updated as well.

Reimplemented from TagLib::File.

strip()

void TagLib::WavPack::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.

Note

This will also invalidate pointers to the tags as their memory will be freed.

In order to make the removal permanent save() still needs to be called

tag()

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

overridevirtual

Returns the Tag for this file. This will be an APE tag, an ID3v1 tag or a combination of the two.

Implements TagLib::File.
