Examples of java.nio.IntBuffer.order()

java.nio.IntBuffer.order()
Returns the byte order used by this buffer when converting ints from/to bytes.
If this buffer is not based on a byte buffer, then always return the platform's native byte order.
@return The byte order used by this buffer when convertingints from/to bytes.
