Examples of BinaryDecoder

co.cask.cdap.common.io.BinaryDecoder
An {@link Decoder} for binary-format data.
co.cask.tephra.snapshot.BinaryDecoder
An decoder to help read snapshots in binary format.
co.cask.tigon.io.BinaryDecoder
An {@link Decoder} for binary-format data.
org.apache.avro.io.BinaryDecoder
An {@link Decoder} for binary-format data.
Instances are created using {@link DecoderFactory}.
This class may read-ahead and buffer bytes from the source beyond what is required to serve its read methods. The number of unused bytes in the buffer can be accessed by inputStream().remaining(), if the BinaryDecoder is not 'direct'. @see Encoder
org.apache.commons.codec.BinaryDecoder
This interface defines common decoding methods for decoders which decode byte arrays. @author Tim O'Brien @version $Revision: 1.1 $ $Date: 2003/04/25 17:50:56 $
