If the list is truncated, the buffer will not be reallocated (use trimToSize() if you need a truncated buffer), but the truncated values will be reset to the default value (zero). If the list is expanded, the elements beyond the current size are initialized with JVM-defaults (zero or null values).
  - size
```

public void trimToSize()
```
    Trim the internal buffer to the current size.

    Specified by:
    
    clear in interface ShortCollection
    
    See Also:
    
    ShortCollection.release()
  - release

    Overrides:
    
    toArray in class AbstractShortCollection
  - clone

```
    Overrides:

```
    Compare index-aligned elements against another ShortIndexedContainer.
  - iterator
```
public java.util.Iterator<ShortCursor> iterator()
```
    Returns an iterator to a cursor traversing the collection. The order of traversal is not defined. More than one cursor may be active at a time. The behavior of iterators is undefined if structural changes are made to the underlying collection.
    The iterator is implemented as a cursor and it returns the same cursor instance on every call to Iterator.next() (to avoid boxing of primitive types). To read the current list's value (or index in the list) use the cursor's public fields. An example is shown below.
```
 for (ShortCursor<short> c : container) {
   System.out.println("index=" + c.index + " value=" + c.value);
 }
 
```
    Specified by:
    
    iterator in interface ShortContainer

    iterator in interface java.lang.Iterable<ShortCursor>
  - forEach
```
public <T extends ShortProcedure> T forEach(T procedure)
```
    Applies a procedure to all container elements. Returns the argument (any subclass of ShortProcedure. This lets the caller to call methods of the argument by chaining the call (even if the argument is an anonymous type) to retrieve computed values, for example (IntContainer):
```
 int count = container.forEach(new IntProcedure() {
   int count; // this is a field declaration in an anonymous class.
 
   public void apply(int value) {
     count++;
   }
 }).count;
 
```
    Specified by:
    
    forEach in interface ShortContainer

                                            int toIndex)
```
    Applies procedure to a slice of the list, fromIndex, inclusive, to toIndex, exclusive.
  - removeAll
```
public int removeAll(ShortPredicate predicate)
```
    Removes all elements in this collection for which the given predicate returns true.
    
    Specified by:
    
    removeAll in interface ShortCollection
    
    Returns:
    
    Returns the number of removed elements.
  - forEach
```
public <T extends ShortPredicate> T forEach(T predicate)
```
    Applies a predicate to container elements as long, as the predicate returns true. The iteration is interrupted otherwise.
