This is an implementation of ID3v2 unique file identifier frames.
This frame is used to identify the file in an arbitrary database identified by the owner field.An implementation of ID3v2 unique identifier frames
TagLib::ID3v2::UniqueFileIdentifierFrame::UniqueFileIdentifierFrame | ( | const ByteVector & | data | ) |
Creates a unique file identifier frame based on data.
TagLib::ID3v2::UniqueFileIdentifierFrame::UniqueFileIdentifierFrame | ( | const String & | owner, |
const ByteVector & | id | ||
) |
Creates a unique file identifier frame with the owner owner and the identification id.

UFID frames each have a unique owner.
This searches for a UFID frame with the owner o and returns a pointer to it.
ByteVector TagLib::ID3v2::UniqueFileIdentifierFrame::identifier | ( | ) | const |
Returns the unique identifier.
Though sometimes this is a text string it also may be binary data and as much should be assumed when handling it.
String TagLib::ID3v2::UniqueFileIdentifierFrame::owner | ( | ) | const |
Returns the owner for the frame; essentially this is the key for determining which identification scheme this key belongs to.
This will usually either be an email address or URL for the person or tool used to create the unique identifier.
|
protectedvirtual |
Called by parse() to parse the field data.
It makes this information available through the public API. This must be overridden by the subclasses.
Implements TagLib::ID3v2::Frame.

protectedvirtual |
Render the field data back to a binary format in a ByteVector.
This must be overridden by subclasses.
Implements TagLib::ID3v2::Frame.
void TagLib::ID3v2::UniqueFileIdentifierFrame::setIdentifier | ( | const ByteVector & | v | ) |
Sets the unique file identifier to v.
void TagLib::ID3v2::UniqueFileIdentifierFrame::setOwner | ( | const String & | s | ) |
Sets the owner of the identification scheme to s.
|

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.
