DataInput, DataOutputpublic class LittleEndianRandomAccessFile extends Object implements DataInput, DataOutput
RandomAccessFile that is capable of reading
and writing data in little endian byte order.
Warning:
The DataInput and DataOutput interfaces
specifies big endian byte order in their documentation.
This means that this class is, strictly speaking, not a proper
implementation. However, I don't see a reason for the these interfaces to
specify the byte order of their underlying representations.
