Examples of BinaryEncoder

co.cask.cdap.common.io.BinaryEncoder
An {@link Encoder} for binary-format data.
co.cask.tephra.snapshot.BinaryEncoder
An encoder to help encode snapshots in binary format.
co.cask.tigon.io.BinaryEncoder
An {@link Encoder} for binary-format data.
org.apache.avro.io.BinaryEncoder
Low-level support for serializing Avro values. This class has two types of methods. One type of methods support the writing of leaf values (for example, {@link #writeLong} and{@link #writeString}). These methods have analogs in {@link Decoder}. The other type of methods support the writing of maps and arrays. These methods are {@link #writeArrayStart}, {@link #startItem}, and {@link #writeArrayEnd} (and similar methods formaps). Some implementations of {@link Encoder} handle thebuffering required to break large maps and arrays into blocks, which is necessary for applications that want to do streaming. (See {@link #writeArrayStart} for details on these methods.) @see Decoder
org.apache.commons.codec.BinaryEncoder
A binary encoder contains methods common to all encoders for binary data. @author Tim O'Brien @version $Revision: 1.1 $ $Date: 2003/04/25 17:50:56 $
