IntSingletonSet

public IntSingletonSet(int value)

Method Detail

getMember

public int getMember()

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

copy

public IntSet copy()

Description copied from interface: IntSet

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

Specified by:

copy in interface IntSet

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

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 interface IntSet

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

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)

Description copied from interface: IntSet

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()

Description copied from interface: IntSet

Get an iterator over the values

Specified by:

iterator in interface IntSet

Returns:

an iterator over the integers in the set

union

public IntSet union(IntSet other)

Description copied from interface: IntSet

Form a new set that is the union of two IntSets.

Specified by:

union in interface IntSet

Parameters:

other - the second set

Returns:

the union of the two sets

intersect

public IntSet intersect(IntSet other)

Description copied from interface: IntSet

Form a new set that is the intersection of two IntSets.

Specified by:

intersect in interface IntSet

Parameters:

other - the second set

Returns:

the intersection of the two sets

except

public IntSet except(IntSet other)

Description copied from interface: IntSet

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.

Specified by:

except in interface IntSet

Parameters:

other - the second set

Returns:

the intersection of the two sets

containsAll

public boolean containsAll(IntSet other)

Description copied from interface: IntSet

Test if this set is a superset of another set

Specified by:

containsAll in interface IntSet

Parameters:

other - the other set

Returns:

true if every item in the other set is also in this set
