- Method Detail
  - makeReadOnlyCopy
```
void makeReadOnlyCopy()
```
  - isOriginal
```
boolean isOriginal()
```
    Returns:
    
    true if this cow version is the same as the original. true means the index has not been updated

```
    Returns:
    
    The number of elements in the index
  - iterator
```
java.util.Iterator<T> iterator()
```
    Returns:
    
    iterator over all the elements
  - copyToArray
```
int copyToArray(T[] target,
                int startingIndexInTarget)
```
    Copy FS refs to target from this index part
    
    Parameters:
    
    target - the target array to copy into
    
    startingIndexInTarget - the starting index in the target array
    
    Returns:
    
    startingIndexInTarget + size
