## Detailed Description

This class wraps the FLAC__StreamDecoder. If you are decoding from a file, FLAC::Decoder::File may be more convenient.

The usage of this class is similar to FLAC__StreamDecoder, except instead of providing callbacks to FLAC__stream_decoder_init*_stream(), you will inherit from this class and override the virtual callback functions with your own implementations, then call init() or init_ogg(). The rest of the calls work the same as in the C layer.

Only the read, write, and error callbacks are mandatory. The others are optional; this class provides default implementations that do nothing. In order for seeking to work you must overide seek_callback(), tell_callback(), length_callback(), and eof_callback().
