getCodec
public static Codec getCodec(int value, java.io.InputStream in, Codec defaultCodec) throws java.io.IOException, Pack200Exception
Returns the codec specified by the given value byte and optional byte header. If the value is >= 116, then bytes may be consumed from the secondary input stream, which is taken to be the contents of the band_headers byte array. Since the values from this are consumed and not repeated, the input stream should be reused for subsequent encodings. This does not therefore close the input stream.- Parameters:
value
- the canonical encoding valuein
- the input stream to read additional byte headers fromdefaultCodec
- TODO- Returns:
- the corresponding codec, or
null
if the default should be used - Throws:
java.io.IOException
- if there is a problem reading from the input stream (which in reality, is never, since the band_headers are likely stored in a byte array and accessed via a ByteArrayInputStream. However, an EOFException could occur if things go wrong)Pack200Exception
