Detailed Description

ID3v2 User defined URL frame.

This is a specialization of URL link frames that allows for user defined entries. Each entry has a description in addition to the normal list of fields that a URL link frame has.

This description identifies the frame and must be unique.

Constructor & Destructor Documentation

◆ UserUrlLinkFrame() [1/4]

TagLib::ID3v2::UserUrlLinkFrame::UserUrlLinkFrame ( String::Type  encoding = String::Latin1)

Constructs an empty user defined URL link frame. For this to be a useful frame both a description and text must be set.

◆ UserUrlLinkFrame() [2/4]

TagLib::ID3v2::UserUrlLinkFrame::UserUrlLinkFrame ( const ByteVector data)

This is a dual purpose constructor. data can either be binary data that should be parsed or (at a minimum) the frame ID.

◆ ~UserUrlLinkFrame()

TagLib::ID3v2::UserUrlLinkFrame::~UserUrlLinkFrame ( )

Destroys this UserUrlLinkFrame instance.

◆ UserUrlLinkFrame() [3/4]

TagLib::ID3v2::UserUrlLinkFrame::UserUrlLinkFrame ( const UserUrlLinkFrame )

◆ UserUrlLinkFrame() [4/4]

TagLib::ID3v2::UserUrlLinkFrame::UserUrlLinkFrame ( const ByteVector data,
Header h 

The constructor used by the FrameFactory.

Member Function Documentation

◆ asProperties()

PropertyMap TagLib::ID3v2::UserUrlLinkFrame::asProperties ( ) const

Parses the UserUrlLinkFrame as PropertyMap. The description() is taken as key, and the URL as a single value.

  • if description() is empty, the key will be "URL".
  • otherwise, if description() is not a valid key (e.g. containing non-ASCII characters), the returned map will contain an entry "WXXX/<description>" in its unsupportedData() list.

Reimplemented from TagLib::ID3v2::UrlLinkFrame.

◆ description()

String TagLib::ID3v2::UserUrlLinkFrame::description ( ) const

Returns the description for this frame.

◆ find()

static UserUrlLinkFrame * TagLib::ID3v2::UserUrlLinkFrame::find ( const Tag tag,
const String description 

Searches for the user defined url frame with the description description in tag. This returns null if no matching frames were found.

◆ operator=()

UserUrlLinkFrame & TagLib::ID3v2::UserUrlLinkFrame::operator= ( const UserUrlLinkFrame )

◆ parseFields()

void TagLib::ID3v2::UserUrlLinkFrame::parseFields ( const ByteVector data)

Called by parse() to parse the field data. It makes this information available through the public API. This must be overridden by the subclasses.

Reimplemented from TagLib::ID3v2::UrlLinkFrame.

◆ renderFields()

ByteVector TagLib::ID3v2::UserUrlLinkFrame::renderFields ( ) const

Render the field data back to a binary format in a ByteVector. This must be overridden by subclasses.

Reimplemented from TagLib::ID3v2::UrlLinkFrame.

◆ setDescription()

void TagLib::ID3v2::UserUrlLinkFrame::setDescription ( const String s)

Sets the description of the frame to s. s must be unique.

◆ setTextEncoding()

void TagLib::ID3v2::UserUrlLinkFrame::setTextEncoding ( String::Type  encoding)

Sets the text encoding to be used when rendering this frame to encoding.

See also

◆ textEncoding()

String::Type TagLib::ID3v2::UserUrlLinkFrame::textEncoding ( ) const

Returns the text encoding that will be used in rendering this frame. This defaults to the type that was either specified in the constructor or read from the frame when parsed.

See also

◆ toString()

String TagLib::ID3v2::UserUrlLinkFrame::toString ( ) const

This returns the textual representation of the data in the frame. Subclasses must reimplement this method to provide a string representation of the frame's data.

Reimplemented from TagLib::ID3v2::UrlLinkFrame.
