Constructor Detail

### IntRangeSet

    public IntRangeSet()

  Create an empty set

### IntRangeSet

    public IntRangeSet(IntRangeSet input)

  Create one IntRangeSet as a copy of another

Method Detail

### clear

    public void clear()

  Description copied from interface: `IntSet`
  Clear the contents of the IntSet (making it an empty set)

  Specified by:
    `clear` in interface `IntSet`

### size

    public int size()

  Description copied from interface: `IntSet`
  Get the number of integers in the set

  Specified by:
    `size` in interface `IntSet`
  Returns:
    the size of the set

### isEmpty

    public boolean isEmpty()

  Description copied from interface: `IntSet`
  Determine if the set is empty

  Specified by:
    `isEmpty` in interface `IntSet`
  Returns:
    true if the set is empty, false if not

### contains

    public boolean contains(int value)

  Description copied from interface: `IntSet`
  Determine whether a particular integer is present in the set

  Specified by:
    `contains` in interface `IntSet`
  Parameters:
    `value` - the integer under test
  Returns:
    true if value is present in the set, false if not

### remove

    public boolean remove(int value)

  Description copied from interface: `IntSet`
  Remove an integer from the set

  Specified by:
    `remove` in interface `IntSet`
  Parameters:
    `value` - the integer to be removed
  Returns:
    true if the integer was present in the set, false if it was not present

### add

    public boolean add(int value)

  Add an integer to the set

  Specified by:
    `add` in interface `IntSet`
  Parameters:
    `value` - the integer to be added
  Returns:
    true if the integer was added, false if it was already present

### iterator

    public IntIterator iterator()

  Get an iterator over the values

  Specified by:
    `iterator` in interface `IntSet`

### toString

    public String toString()

  Overrides:
    `toString` in class `Object`

### equals

    public boolean equals(Object other)

  Test whether this set has exactly the same members as another set. Note that IntRangeSet values are NOT comparable with other implementations of IntSet

  Overrides:
    `equals` in class `Object`

### hashCode

    public int hashCode()

  Construct a hash key that supports the equals() test

  Overrides:
    `hashCode` in class `Object`

### containsAll

    public boolean containsAll(IntSet other)

  Test if this set is a superset of another set

  Specified by:
    `containsAll` in interface `IntSet`

### main

    public static void main(String[] args)
                     throws Exception

  Throws:
    `Exception`
