    listIterator in interface LongList
  - removeElementAt
```
public long removeElementAt(int index)
```
    Description copied from interface: LongList
    
    Removes the element at the specified position in (optional operation). Any subsequent elements are shifted to the left, subtracting one from their indices. Returns the element that was removed.
    
    Specified by:
    
    removeElementAt in interface LongList
    
    Parameters:
    index - the index of the element to remove
    
    Returns:
    the value of the element that was removed
  - set
```
public long set(int index,
       long element)
```
    Description copied from interface: LongList
    
    Replaces the element at the specified position in me with the specified element (optional operation).
    
    Specified by:
    
    set in interface LongList

    element - the value to be stored at the specified position
    
    Returns:
    the value previously stored at the specified position
  - subList
```
public LongList subList(int fromIndex,
               int toIndex)
```
    Description copied from interface: LongList
    
    Returns a view of the elements within me between the specified fromIndex, inclusive, and toIndex, exclusive. The returned LongList is backed by me, so that any changes in the returned list are reflected in me, and vice-versa. The returned list supports all of the optional operations that I support.
    Note that when fromIndex == toIndex, the returned list is initially empty, and when fromIndex == 0 && toIndex == size() the returned list is my "improper" sublist, containing all my elements.
    The semantics of the returned list become undefined if I am structurally modified in any way other than via the returned list.
    
    Specified by:
    
    subList in interface LongList
    
    Parameters:
    fromIndex - the smallest index (inclusive) in me that appears in the returned list
    toIndex - the largest index (exclusive) in me that appears in the returned list
    
    Returns:
    a view of this list from fromIndex (inclusive) to toIndex (exclusive)
  - equals
```
public boolean equals(Object obj)
```
    Description copied from interface: LongList
    
    Returns true iff that is an LongList that contains the same elements in the same order as me. In other words, returns true iff that is a LongList that has the same size as me, and for which the elements returned by its iterator are equal (==) to the corresponding elements within me. (This contract ensures that this method works properly across different implementations of the LongList interface.)
    
    Specified by:
    
    equals in interface LongList
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    obj - the object to compare to me
    
    Returns:
    true iff that is an LongList that contains the same elements in the same order as me
  - hashCode
```
public int hashCode()
```
    Description copied from interface: LongList
    Returns my hash code.
    The hash code of an LongList is defined to be the result of the following calculation:
```
 int hash = 1;
 for(LongIterator iter = iterator(); iter.hasNext(); ) {
   long value = iter.next();
   hash = 31*hash + (int)(value ^ (value >>> 32));
 }
```
    This contract ensures that this method is consistent with equals and with the hashCode method of a List of Longs.
    Specified by:
    
    hashCode in interface LongList
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    my hash code
  - getCollection
```
protected final Collection getCollection()
```
  - add
```
public boolean add(long element)
```
    Description copied from interface: LongCollection
    
    Ensures that I contain the specified element (optional operation). Returns true iff I changed as a result of this call.
    If a collection refuses to add the specified element for any reason other than that it already contains the element, it must throw an exception (rather than simply returning false). This preserves the invariant that a collection always contains the specified element after this call returns.
    
    Specified by:
    
    add in interface LongCollection
    
    Parameters:
    element - the value whose presence within me is to be ensured
    
    Returns:
    true iff I changed as a result of this call
  - addAll
```
public boolean addAll(LongCollection c)
```
    Description copied from interface: LongCollection

    Specified by:
    
    addAll in interface LongCollection
    
    Parameters:
    c - the collection of elements whose presence within me is to be ensured
    
    Returns:
    true iff I changed as a result of this call
  - clear
```
public void clear()
```
    Description copied from interface: LongCollection
    
    Removes all my elements (optional operation). I will be empty after this method successfully returns.

    containsAll in interface LongCollection
    
    Parameters:
    c - the collection of elements whose presence within me is to be tested
    
    Returns:

```
    Description copied from interface: LongCollection
    
    Removes a single occurrence of the specified element (optional operation).
    
    Specified by:
    
    removeElement in interface LongCollection
    
    Parameters:
    element - the element to remove, if present
    
    Returns:

Note that this includes the case in which the given collection is this collection, and it is not empty.
    
    Specified by:
    
    removeAll in interface LongCollection
    
    Parameters:
    c - the collection of elements to remove
    
    Returns:
    true iff I contained the at least one of the specified elements, in other words, returns true iff I changed as a result of this call
  - retainAll
```
public boolean retainAll(LongCollection c)
```
    Description copied from interface: LongCollection
    
    Removes all of my elements that are not contained in the specified collection (optional operation). (In other words, retains only my elements that are contained in the specified collection.) The behavior of this method is unspecified if the given collection is modified while this method is executing.
    
    Specified by:
    
    retainAll in interface LongCollection
    
    Parameters:
    c - the collection of elements to retain

```
public long[] toArray()
```
    Description copied from interface: LongCollection
    
    Returns an array containing all of my elements. The length of the returned array will be equal to my size.
    The returned array will be independent of me, so that callers may modify that returned array without modifying this collection.
    When I guarantee the order in which elements are returned by an iterator, the returned array will contain elements in the same order.
    
    Specified by:
    
    toArray in interface LongCollection
    
    Returns:
    an array containing all my elements
  - toArray
```
public long[] toArray(long[] dest)
```
    Description copied from interface: LongCollection

    The returned array will be independent of me, so that callers may modify that returned array without modifying this collection.
    When I guarantee the order in which elements are returned by an iterator, the returned array will contain elements in the same order.
    
    Specified by:
    
    toArray in interface LongCollection
    
    Parameters:
    dest - an array that may be used to contain the elements
