Method Detail
-
getInstance
public static IntEmptySet getInstance()
-
copy
public IntSet copy()
Description copied from interface:IntSetCreate a copy of this IntSet that leaves the original unchanged.
-
mutableCopy
public IntSet mutableCopy()
Description copied from interface:IntSetCreate a copy of this IntSet that contains the same set of integers.- Specified by:
mutableCopyin 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
-
isMutable
public boolean isMutable()
Description copied from interface:IntSetAsk whether the set permits in-situ modifications using add() and remove()
-
clear
public void clear()
Description copied from interface:IntSetClear the contents of the IntSet (making it an empty set)
-
size
public int size()
Description copied from interface:IntSetGet the number of integers in the set
-
isEmpty
public boolean isEmpty()
Description copied from interface:IntSetDetermine if the set is empty
-
contains
public boolean contains(int value)
Description copied from interface:IntSetDetermine whether a particular integer is present in the set
-
remove
public boolean remove(int value)
Description copied from interface:IntSetRemove an integer from the set
-
add
public boolean add(int value)
Description copied from interface:IntSetAdd an integer to the set
-
iterator
public IntIterator iterator()
Description copied from interface:IntSetGet an iterator over the values
-
union
public IntSet union(IntSet other)
Description copied from interface:IntSetForm a new set that is the union of two IntSets.
-
intersect
public IntSet intersect(IntSet other)
Description copied from interface:IntSetForm a new set that is the intersection of two IntSets.
-
except
public IntSet except(IntSet other)
Description copied from interface:IntSetForm a new set that is the difference of this set and another set. The result will either be an immutable object, or a newly constructed object.
-
containsAll
public boolean containsAll(IntSet other)
Description copied from interface:IntSetTest if this set is a superset of another set- Specified by:
containsAllin interfaceIntSet- Parameters:
other- the other set- Returns:
- true if every item in the other set is also in this set
