Detailed Description

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

This implements and provides an interface for APE 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 APE files.

Member Enumeration Documentation

◆ 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::APE::File::File ( FileName  file,
bool  readProperties = true,
Properties::ReadStyle  propertiesStyle = Properties::Average 
)

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

Constructs an APE 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::APE::File::~File ( )
overridevirtual

Destroys this instance of the File.

Reimplemented from TagLib::File.

◆ File() [3/3]

TagLib::APE::File::File ( const File )
delete

Member Function Documentation

◆ APETag()

APE::Tag * TagLib::APE::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 APE::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::APE::File::audioProperties ( ) const
overridevirtual

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

Implements TagLib::File.

◆ hasAPETag()

bool TagLib::APE::File::hasAPETag ( ) const

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

See also
APETag()

◆ hasID3v1Tag()

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

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

See also
ID3v1Tag()

◆ ID3v1Tag()

ID3v1::Tag * TagLib::APE::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 APE::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::APE::File::isSupported ( IOStream stream)
static

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

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

◆ operator=()

File & TagLib::APE::File::operator= ( const File )
delete

◆ properties()

PropertyMap TagLib::APE::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::APE::File::removeUnsupportedProperties ( const StringList properties)
overridevirtual

Removes unsupported properties. Forwards to the actual Tag's removeUnsupportedProperties() function.

Reimplemented from TagLib::File.

◆ save()

bool TagLib::APE::File::save ( )
overridevirtual

Saves the file.

Note
According to the official Monkey's Audio SDK, an APE file can only have either ID3V1 or APE tags, so a parameter is used here.

Implements TagLib::File.

◆ setProperties()

PropertyMap TagLib::APE::File::setProperties ( const PropertyMap )
overridevirtual

Implements the unified property interface – import function. Creates an APEv2 tag if necessary. A potentially existing ID3v1 tag will be updated as well.

Reimplemented from TagLib::File.

◆ strip()

void TagLib::APE::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::APE::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.
