- Constructor Detail
  - DefaultShuffleOrder
```
public DefaultShuffleOrder(int length)
```
    Creates an instance with a specified length.
    
    Parameters:
    
    length - The length of the shuffle order.
  - DefaultShuffleOrder
```
public DefaultShuffleOrder(int length,
                           long randomSeed)
```
    Creates an instance with a specified length and the specified random seed. Shuffle orders of the same length initialized with the same random seed are guaranteed to be equal.
    
    Parameters:
    
    length - The length of the shuffle order.
    
    randomSeed - A random seed.
  - DefaultShuffleOrder
```
public DefaultShuffleOrder(int[] shuffledIndices,
                           long randomSeed)
```
    Creates an instance with a specified shuffle order and the specified random seed. The random seed is used for cloneAndInsert(int, int) invocations.
    
    Parameters:
    
    shuffledIndices - The shuffled indices to use as order.
    
    randomSeed - A random seed.

```
    Description copied from interface: ShuffleOrder
    
    Returns a copy of the shuffle order with newly inserted elements.
    
    Specified by:
    
    cloneAndInsert in interface ShuffleOrder
    
    Parameters:
    
    insertionIndex - The index in the unshuffled order at which elements are inserted.
