Field Detail

BIG_ENDIAN

public static final ByteOrder BIG_ENDIAN

Constant denoting big-endian byte order. In this order, the bytes of a multibyte value are ordered from most significant to least significant.

LITTLE_ENDIAN

public static final ByteOrder LITTLE_ENDIAN

Constant denoting little-endian byte order. In this order, the bytes of a multibyte value are ordered from least significant to most significant.

Method Detail

nativeOrder

public static ByteOrder nativeOrder()

Retrieves the native byte order of the underlying platform.

This method is defined so that performance-sensitive Java code can allocate direct buffers with the same byte order as the hardware. Native code libraries are often more efficient when such buffers are used.

Returns:

The native byte order of the hardware upon which this Java virtual machine is running

toString

public String toString()

Constructs a string describing this object.

This method returns the string "BIG_ENDIAN" for BIG_ENDIAN and "LITTLE_ENDIAN" for LITTLE_ENDIAN.

Overrides:

toString in class Object

Returns:

The specified string
