Method Detail

fill

protected void fill()
             throws IOException

called from the super class whenever more PCM data is needed.

Overrides:

fill in class RingedAudioInputStream

Throws:

IOException

initDecoder

protected void initDecoder()
                    throws IOException

Initialize the Flac Decoder after reading the Header.

Throws:
