Class LittleEndianDataOutputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.io.DataOutput, java.io.Flushable, java.lang.AutoCloseable

    @Beta
    public class LittleEndianDataOutputStream
    extends java.io.FilterOutputStream
    implements java.io.DataOutput
    An implementation of DataOutput that uses little-endian byte ordering for writing char, short, int, float, double, and long values.

    Note: This class intentionally violates the specification of its supertype DataOutput, which explicitly requires big-endian byte order.
