Interface IntSet

All Known Implementing Classes:

AbstractIntSet, IntArraySet, IntComplementSet, IntEmptySet, IntHashSet, IntRangeSet, IntSingletonSet, IntUniversalSet

public interface IntSet

A set of integers represented as int values

Method Summary

boolean	add(int value) Add an integer to the set
void	clear() Clear the contents of the IntSet (making it an empty set)
boolean	contains(int value) Determine whether a particular integer is present in the set
boolean	containsAll(IntSet other) Test if this set is a superset of another set
IntSet	copy() Create a copy of this IntSet that leaves the original unchanged.
IntSet	except(IntSet other) Form a new set that is the difference of this set and another set.
IntSet	intersect(IntSet other) Form a new set that is the intersection of this IntSet and another.
boolean	isEmpty() Determine if the set is empty
IntIterator	iterator() Get an iterator over the values
IntSet	mutableCopy() Create a copy of this IntSet that contains the same set of integers.
boolean	remove(int value) Remove an integer from the set
int	size() Get the number of integers in the set
IntSet	union(IntSet other) Form a new set that is the union of this IntSet and another.

Method Detail

copy

IntSet copy()

Create a copy of this IntSet that leaves the original unchanged.

Returns:

an IntSet containing the same integers. The result will not necessarily be the same class as the original. It will either be an immutable object, or a newly constructed object.

mutableCopy

IntSet mutableCopy()

Create a copy of this IntSet that contains the same set of integers.

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

clear

void clear()

Clear the contents of the IntSet (making it an empty set)

size

int size()

Get the number of integers in the set

Returns:

the size of the set

isEmpty

boolean isEmpty()

Determine if the set is empty

Returns:

true if the set is empty, false if not

contains

boolean contains(int value)

Determine whether a particular integer is present in the set

Parameters:

value - the integer under test

Returns:

true if value is present in the set, false if not

remove

boolean remove(int value)

Remove an integer from the set

Parameters:

value - the integer to be removed

Returns:

true if the integer was present in the set, false if it was not present

add

boolean add(int value)

Add an integer to the set

Parameters:

value - the integer to be added

Returns:

true if the integer was added, false if it was already present

iterator

IntIterator iterator()

Get an iterator over the values

Returns:

an iterator over the integers in the set

union

IntSet union(IntSet other)

Form a new set that is the union of this IntSet and another. The result will either be an immutable object, or a newly constructed object.

Parameters:

other - the second set

Returns:

the union of the two sets

intersect

IntSet intersect(IntSet other)

Form a new set that is the intersection of this IntSet and another. The result will either be an immutable object, or a newly constructed object.

Parameters:

other - the second set

Returns:

the intersection of the two sets

except

IntSet except(IntSet other)

Form 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.

Parameters:

other - the second set

Returns:

the intersection of the two sets

containsAll

boolean containsAll(IntSet other)

Test if this set is a superset of another set

Parameters:

other - the other set

Returns:

true if every integer in the other set is also present in this set
