Examples of java.nio.DoubleBuffer.order()

java.nio.DoubleBuffer.order()
Returns the byte order used by this buffer when converting doubles 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 convertingdoubles from/to bytes.

        assertNotSame(buf, readonly);
        assertTrue(readonly.isReadOnly());

        assertContentEquals(buf, readonly);


        // readonly's position, mark, and limit should be independent to buf
