## Class LittleEndianDataOutputStream

- java.lang.Object
- - java.io.OutputStream
  - - java.io.FilterOutputStream
    - - com.google.common.io.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.

  Since:
    8.0

    Modifier and Type | Method and Description
    --- | ---
    `void` | `close()`
