Detailed Description

A frame type unknown to TagLib.

This class represents a frame type not known (or more often simply unimplemented) in TagLib. This is here provide a basic API for manipulating the binary data of unknown frames and to provide a means of rendering such unknown frames.

Please note that a cleaner way of handling frame types that TagLib does not understand is to subclass ID3v2::Frame and ID3v2::FrameFactory to have your frame type supported through the standard ID3v2 mechanism.

Member Function Documentation

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

Returns the field data (everything but the header) for this frame.

virtual void TagLib::ID3v2::UnknownFrame::parseFields ( const ByteVector data)
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.

virtual ByteVector TagLib::ID3v2::UnknownFrame::renderFields ( ) const
protectedvirtual

Render the field data back to a binary format in a ByteVector.

This must be overridden by subclasses.

Implements TagLib::ID3v2::Frame.

virtual String TagLib::ID3v2::UnknownFrame::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.

Implements TagLib::ID3v2::Frame.
