public static Codec getCodec(final int value, final InputStream in, final Codec defaultCodec) throws IOException, Pack200Exception

Gets 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:int: the canonical encoding value
in:InputStream: the input stream to read additional byte headers from
defaultCodec:Codec: TODO

Returns:Codec

the corresponding codec, or null if the default should be used

Exceptions

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:: TODO
