This is an implementation of the ID3v1 format. ID3v1 is both the simplist and most common of tag formats but is rather limited. Because of its pervasiveness and the way that applications have been written around the fields that it provides, the generic TagLib::Tag API is a mirror of what is provided by ID3v1.
ID3v1 tags should generally only contain Latin1 information. However because many applications do not follow this rule there is now support for overriding the ID3v1 string handling using the ID3v1::StringHandler class. Please see the documentation for that class for more information.
TagLib::ID3v1::Tag::Tag | ( | ) |
Create an ID3v1 tag with default values.
Reimplemented from TagLib::Tag.
TagLib::ID3v1::Tag::Tag | ( | File * | file, | |
long | tagOffset | |||
) |
Create an ID3v1 tag and parse the data in file starting at tagOffset.
virtual TagLib::ID3v1::Tag::~Tag | ( | ) | [virtual] |
Destroys this Tag instance.
Reimplemented from TagLib::Tag.
virtual String TagLib::ID3v1::Tag::album | ( | ) | const [virtual] |
Returns the album name; if no album name is present in the tag String::null will be returned.
Implements TagLib::Tag.
virtual String TagLib::ID3v1::Tag::artist | ( | ) | const [virtual] |
Returns the artist name; if no artist name is present in the tag String::null will be returned.
Implements TagLib::Tag.
virtual String TagLib::ID3v1::Tag::comment | ( | ) | const [virtual] |
Returns the track comment; if no comment is present in the tag String::null will be returned.
Implements TagLib::Tag.
static ByteVector TagLib::ID3v1::Tag::fileIdentifier | ( | ) | [static] |
Returns the string "TAG" suitable for usage in locating the tag in a file.
virtual String TagLib::ID3v1::Tag::genre | ( | ) | const [virtual] |
Returns the genre name; if no genre is present in the tag String::null will be returned.
Implements TagLib::Tag.
void TagLib::ID3v1::Tag::parse | ( | const ByteVector & | data | ) | [protected] |
Pareses the body of the tag in data.
void TagLib::ID3v1::Tag::read | ( | ) | [protected] |
Reads from the file specified in the constructor.
ByteVector TagLib::ID3v1::Tag::render | ( | ) | const |
Renders the in memory values to a ByteVector suitable for writing to the file.
virtual void TagLib::ID3v1::Tag::setAlbum | ( | const String & | s | ) | [virtual] |
Sets the album to s. If s is String::null then this value will be cleared.
Implements TagLib::Tag.
virtual void TagLib::ID3v1::Tag::setArtist | ( | const String & | s | ) | [virtual] |
Sets the artist to s. If s is String::null then this value will be cleared.
Implements TagLib::Tag.
virtual void TagLib::ID3v1::Tag::setComment | ( | const String & | s | ) | [virtual] |
Sets the comment to s. If s is String::null then this value will be cleared.
Implements TagLib::Tag.
virtual void TagLib::ID3v1::Tag::setGenre | ( | const String & | s | ) | [virtual] |
Sets the genre to s. If s is String::null then this value will be cleared. For tag formats that use a fixed set of genres, the appropriate value will be selected based on a string comparison. A list of available genres for those formats should be available in that type's implementation.
Implements TagLib::Tag.
static void TagLib::ID3v1::Tag::setStringHandler | ( | const StringHandler * | handler | ) | [static] |
Sets the string handler that decides how the ID3v1 data will be converted to and from binary data.
virtual void TagLib::ID3v1::Tag::setTitle | ( | const String & | s | ) | [virtual] |
Sets the title to s. If s is String::null then this value will be cleared.
Implements TagLib::Tag.
virtual void TagLib::ID3v1::Tag::setTrack | ( | uint | i | ) | [virtual] |
Sets the track to i. If s is 0 then this value will be cleared.
Implements TagLib::Tag.
virtual void TagLib::ID3v1::Tag::setYear | ( | uint | i | ) | [virtual] |
Sets the year to i. If s is 0 then this value will be cleared.
Implements TagLib::Tag.
virtual String TagLib::ID3v1::Tag::title | ( | ) | const [virtual] |
Returns the track name; if no track name is present in the tag String::null will be returned.
Implements TagLib::Tag.
virtual uint TagLib::ID3v1::Tag::track | ( | ) | const [virtual] |
Returns the track number; if there is no track number set, this will return 0.
Implements TagLib::Tag.
virtual uint TagLib::ID3v1::Tag::year | ( | ) | const [virtual] |
Returns the year; if there is no year set, this will return 0.
Implements TagLib::Tag.
