public AbstractIntSet()

Method Detail

containsAll

public boolean containsAll(IntSet other)

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

union

public IntSet union(IntSet other)

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)

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)

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
