Examples of java.nio.ShortBuffer

java.nio.ShortBuffer
A buffer of shorts.
A short buffer can be created in either of the following ways:
- {@link #allocate(int) Allocate} a new short array and create a bufferbased on it;
- {@link #wrap(short[]) Wrap} an existing short array to create a newbuffer;
- Use {@link java.nio.ByteBuffer#asShortBuffer() ByteBuffer.asShortBuffer}to create a short buffer based on a byte buffer.

        assertArrayEquals(new short[]{1, 1, 2, 1, 2, 3, 3, 4}, array.toArray());
        MutableShortArray backedByArray = MutableShortArray.copyOf(array);
        Arrays.reverse(backedByArray);
        array.setAll(backedByArray);
        assertArrayEquals(new short[]{4, 3, 3, 2, 1, 2, 1, 1}, array.toArray());
        ShortBuffer buffer = ByteBuffer.allocateDirect(Short.SIZE / Byte.SIZE * 8).asShortBuffer();
        MutableShortArray notBackedByArray = Arrays.newMutableArray(buffer);
        notBackedByArray.setAll(backedByArray);
        array.setAll(notBackedByArray);
        assertArrayEquals(new short[]{4, 3, 3, 2, 1, 2, 1, 1}, array.toArray());
        UnboundedShortArray tooBig = UnboundedShortArray.copyOf(array);
