All Implemented Interfaces:

java.io.Closeable, java.io.DataInput, java.lang.AutoCloseable, DataInputPlus

public class DataInputBuffer
extends NIODataInputStream

Input stream around a fixed ByteBuffer. Necessary to have this derived class to avoid NIODataInputStream's shuffling of bytes behavior in readNext()
