Method Detail

contains

boolean contains(int i)

Parameters:

i -

Returns:

true iff this set contains integer i

containsAny

boolean containsAny(IntSet set)

Returns:

true iff this set contains integer i

intersection

IntSet intersection(IntSet that)

This implementation must not despoil the original value of "this"

Returns:

a new IntSet which is the intersection of this and that

isEmpty

boolean isEmpty()

Returns:

true iff this set is empty

size

int size()

Returns:

the number of elements in this set

intIterator

IntIterator intIterator()

Returns:

a perhaps more efficient iterator

foreach

void foreach(IntSetAction action)

Invoke an action on each element of the Set

Parameters:

action -

foreachExcluding

void foreachExcluding(IntSet X,
                      IntSetAction action)

Invoke an action on each element of the Set, excluding elements of Set X

Parameters:

action -

max

int max()

Returns:

maximum integer in this set.

sameValue

boolean sameValue(IntSet that)

Returns:

true iff this has the same value as that.

isSubset

boolean isSubset(IntSet that)

Returns:

true iff this is a subset of that.
