- Method Detail
  - contains
```
boolean contains(int i)
```
    Returns:
    
    true iff this set contains integer i
  - containsAny
```
boolean containsAny(IntSet set)
```
    Returns:
    
    true iff this set contains integer i
  - intersection
```
IntSet intersection(IntSet that)
```
    This implementation must not despoil the original value of "this"
    
    Returns:
    
    a new IntSet which is the intersection of this and that
  - union
```
IntSet union(IntSet that)
```
    This implementation must not despoil the original value of "this"
    
    Returns:
    
    a new IntSet containing all elements of this and that
  - isEmpty
```
boolean isEmpty()
```
    Returns:
    
    true iff this set is empty
  - size
```
int size()
```
    Returns:
    
    the number of elements in this set
  - intIterator
```
IntIterator intIterator()
```
    Returns:
    
    a perhaps more efficient iterator
  - foreach
```
void foreach(IntSetAction action)
```
    Invoke an action on each element of the Set
  - foreachExcluding
```
void foreachExcluding(IntSet X,
                      IntSetAction action)
```
    Invoke an action on each element of the Set, excluding elements of Set X
  - max
```
int max()
```
    Returns:
    
    maximum integer in this set.
  - sameValue
```
boolean sameValue(IntSet that)
```
    Returns:
    
    true iff this has the same value as that.
  - isSubset
```
boolean isSubset(IntSet that)
```
    Returns:
    
    true iff this is a subset of that.
