Constructor and Description
FlacAudioFrame(byte[] data, FlacInfo info)
FlacAudioFrame(InputStream stream, FlacInfo info) Creates the frame from the stream, with header sync checking
FlacAudioFrame(int first2, InputStream rawStream, FlacInfo info) Creates the frame from the pre-read 2 bytes and stream, no sync checks.
FlacAudioFrame(int byte1, int byte2, InputStream stream, FlacInfo info) Creates the frame from the pre-read 2 bytes and stream, with header sync checking

Constructor Detail

FlacAudioFrame

public FlacAudioFrame(byte[] data,
              FlacInfo info)
               throws IOException

Throws:

IOException

FlacAudioFrame

public FlacAudioFrame(InputStream stream,
              FlacInfo info)
               throws IOException

Creates the frame from the stream, with header sync checking

Throws:

IOException

FlacAudioFrame

public FlacAudioFrame(int byte1,
              int byte2,
              InputStream stream,
              FlacInfo info)

IOException

FlacAudioFrame

public FlacAudioFrame(int first2,
              InputStream rawStream,
              FlacInfo info)
               throws IOException

Creates the frame from the pre-read 2 bytes and stream, no sync checks. Info is needed, as values of 0 often mean "as per info defaults".
