Detailed Description

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

This implements and provides an interface for MPC 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 MPC files. The only invalid tag combination supported is an ID3v1 tag after an APE tag.

Member Enumeration Documentation

◆ TagTypes

enum TagLib::MPC::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.
ID3v2	Matches ID3v2 tags.
APE	Matches APE tags.
AllTags	Matches all tag types.

Constructor & Destructor Documentation

◆ File() [1/3]

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

Constructs an MPC 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::MPC::File::File	(	IOStream *	stream,
		bool	readProperties = `true`,
		Properties::ReadStyle	propertiesStyle = `Properties::Average`
	)

Constructs an MPC 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::MPC::File::~File ( )

overridevirtual

Destroys this instance of the File.

Reimplemented from TagLib::File.

◆ File() [3/3]

TagLib::MPC::File::File ( const File & )

delete

Member Function Documentation

◆ APETag()

APE::Tag * TagLib::MPC::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. If there already is an ID3v1 tag, the new APE tag will be placed before it.

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 MPC::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::MPC::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::MPC::File::hasAPETag ( ) const

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

See also: APETag()

◆ hasID3v1Tag()

bool TagLib::MPC::File::hasID3v1Tag ( ) const

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

See also: ID3v1Tag()

◆ ID3v1Tag()

ID3v1::Tag * TagLib::MPC::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 MPC::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::MPC::File::isSupported ( IOStream * stream )

static

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

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

◆ operator=()

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

delete

◆ properties()

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

overridevirtual

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

Reimplemented from TagLib::File.

◆ removeUnsupportedProperties()

void TagLib::MPC::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::MPC::File::save ( )

overridevirtual

Saves the file.

This returns true if the save was successful.

Implements TagLib::File.

◆ setProperties()

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

overridevirtual

Implements the unified property interface – import function. Affects only the APEv2 tag which will be created if necessary. If an ID3v1 tag exists, it will be updated as well.

Reimplemented from TagLib::File.

◆ strip()

void TagLib::MPC::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.

◆ tag()

TagLib::Tag * TagLib::MPC::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.
