Detailed Description

An ID3v2 custom text identification frame implementationx.

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

This description identifies the frame and must be unique.

Constructor & Destructor Documentation

TagLib::ID3v2::UserTextIdentificationFrame::UserTextIdentificationFrame ( String::Type  encoding = String::Latin1)
explicit

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

TagLib::ID3v2::UserTextIdentificationFrame::UserTextIdentificationFrame ( const ByteVector &  data)
explicit

Creates a frame based on data.

TagLib::ID3v2::UserTextIdentificationFrame::UserTextIdentificationFrame ( const String &  description,
const StringList &  values,
String::Type  encoding = String::UTF8 
)

Creates a user defined text identification frame with the given description and values.

Member Function Documentation

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

A UserTextIdentificationFrame is parsed into a PropertyMap as follows:

  • the key is the frame's description, uppercased
  • if the description contains '::', only the substring after that separator is considered as key (compatibility with exfalso)
  • if the above rules don't yield a valid key (e.g. containing non-ASCII characters), the returned map will contain an entry "TXXX/<description>" in its unsupportedData() list.
  • The values will be copies of the fieldList().
  • If the description() appears as value in fieldList(), it will be omitted in the value list, in order to be compatible with TagLib which copies the description() into the fieldList().
String TagLib::ID3v2::UserTextIdentificationFrame::description ( ) const

Returns the description for this frame.

StringList TagLib::ID3v2::UserTextIdentificationFrame::fieldList ( ) const
static UserTextIdentificationFrame* TagLib::ID3v2::UserTextIdentificationFrame::find ( Tag *  tag,
const String &  description 
)
static

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

void TagLib::ID3v2::UserTextIdentificationFrame::setDescription ( const String &  s)

Sets the description of the frame to s. s must be unique. You can check for the presence of another user defined text frame of the same type using find() and testing for null.

void TagLib::ID3v2::UserTextIdentificationFrame::setText ( const String &  text)
virtual

Set the text of frame in the sanest way possible. This should only be reimplemented in frames where there is some logical mapping to text.

Note
If the frame type supports multiple text encodings, this will not change the text encoding of the frame; the string will be converted to that frame's encoding. Please use the specific APIs of the frame types to set the encoding if that is desired.

Reimplemented from TagLib::ID3v2::TextIdentificationFrame.

void TagLib::ID3v2::UserTextIdentificationFrame::setText ( const StringList &  fields)
virtual String TagLib::ID3v2::UserTextIdentificationFrame::toString ( ) const
virtual

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::TextIdentificationFrame.
