public class IntHashSet extends AbstractIntSet implements IntSet, java.io.Serializable
Set of int values. This class is modelled on the java.net.Set interface, but it does not implement this interface, because the set members are nint's rather than Objects. Not thread safe.- Author:
- Dominique Devienne, Michael Kay: retrofitted to JDK 1.4, added iterator()

Method Detail
-
copy
public IntSet copy()
Description copied from interface:IntSet
Create a copy of this IntSet that leaves the original unchanged.
-
mutableCopy
public IntSet mutableCopy()
Description copied from interface:IntSet
Create a copy of this IntSet that contains the same set of integers.- Specified by:
mutableCopy
in interfaceIntSet
- Returns:
- an IntSet containing the same integers. The result will not necessarily be the same class as the original. It will always be a mutable object

size
public int size()
Description copied from interface:IntSet
Get the number of integers in the set
-
isEmpty
public boolean isEmpty()
Description copied from interface:IntSet

-
contains
public boolean contains(int value)
Description copied from interface:IntSet
