  - iterator
```
public TIntIterator iterator()
```
    Creates an iterator over the values of the set. The iterator supports element deletion.
    
    Specified by:
    
    iterator in interface TIntCollection
    
    Specified by:
    
    iterator in interface TIntSet
    
    Returns:
    
    an TIntIterator value
  - getNoEntryValue
```
public int getNoEntryValue()
```
    Returns the value that is used to represent null. The default value is generally zero, but can be changed during construction of the collection.
    
    Specified by:
    
    getNoEntryValue in interface TIntCollection
    
    Specified by:
    
    getNoEntryValue in interface TIntSet
    
    Returns:
    
    the value that represents null
  - size
```
public int size()
```
    Returns the number of elements in this set (its cardinality). If this set contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.
    
    Specified by:
    
    size in interface TIntCollection
    
    Specified by:
    
    size in interface TIntSet
    
    Returns:
    
    the number of elements in this set (its cardinality)
  - isEmpty
```
public boolean isEmpty()
```
    Returns true if this set contains no elements.
    
    Specified by:
    
    isEmpty in interface TIntCollection
    
    Specified by:
    
    isEmpty in interface TIntSet
    
    Returns:
    
    true if this set contains no elements
  - contains
```
public boolean contains(int entry)
```
    Returns true if this set contains the specified element.
    
    Specified by:
    
    contains in interface TIntCollection
    
    Specified by:
    
    contains in interface TIntSet
    
    Parameters:
    
    entry - an int value
    
    Returns:
    
    true if the set contains the specified element.
  - toArray
```
public int[] toArray()
```
    Returns an array containing all of the elements in this set. If this set makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.
    The returned array will be "safe" in that no references to it are maintained by this set. (In other words, this method must allocate a new array even if this set is backed by an array). The caller is thus free to modify the returned array.
    This method acts as bridge between array-based and collection-based APIs.
    
    Specified by:
    
    toArray in interface TIntCollection
    
    Specified by:
    
    toArray in interface TIntSet
    
    Returns:
    
    an array containing all the elements in this set
  - toArray
```
public int[] toArray(int[] dest)
```
    Returns an array containing elements in this set.
    If this set fits in the specified array with room to spare (i.e., the array has more elements than this set), the element in the array immediately following the end of the set is set to TIntSet.getNoEntryValue(). (This is useful in determining the length of this set only if the caller knows that this set does not contain any elements representing null.)
    If the native array is smaller than the set size, the array will be filled with elements in Iterator order until it is full and exclude the remainder.
    If this set makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.
    
    Specified by:
    
    toArray in interface TIntCollection
    
    Specified by:
    
    toArray in interface TIntSet
    
    Parameters:
    
    dest - the array into which the elements of this set are to be stored.
    
    Returns:
    
    an int[] containing all the elements in this set

  - equals
```
public boolean equals(java.lang.Object other)
```
    Description copied from interface: TIntSet
    
    Compares the specified object with this set for equality. Returns true if the specified object is also a set, the two sets have the same size, and every member of the specified set is contained in this set (or equivalently, every member of this set is contained in the specified set). This definition ensures that the equals method works properly across different implementations of the set interface.
    
    Specified by:
    
    equals in interface TIntCollection
    
    Specified by:
    
    equals in interface TIntSet
    
    Overrides:
    
    equals in class java.lang.Object
    
    Parameters:
    
    other - object to be compared for equality with this set
    
    Returns:
    
    true if the specified object is equal to this set
  - hashCode
```
public int hashCode()
```
    Description copied from interface: TIntSet
    
    Returns the hash code value for this set. The hash code of a set is defined to be the sum of the hash codes of the elements in the set. This ensures that s1.equals(s2) implies that s1.hashCode()==s2.hashCode() for any two sets s1 and s2, as required by the general contract of Object.hashCode().
    
    Specified by:
    
    hashCode in interface TIntCollection

    hashCode in interface TIntSet
    
    Overrides:
    
    hashCode in class java.lang.Object
    
    Returns:
    
    the hash code value for this set
