Method Detail

clear

public void clear()

Description copied from interface: MutableIntSet

remove all elements from this set

Specified by:

clear in interface MutableIntSet

contains

public boolean contains(int i)

Specified by:

contains in interface IntSet

Returns:

true iff this set contains integer i

Specified by:

containsAny in interface IntSet

Returns:

true iff this set contains integer i

intersection

public IntSet intersection(IntSet that)

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

Specified by:

intersection in interface IntSet

Returns:

a new IntSet which is the intersection of this and that

union

public IntSet union(IntSet that)

Description copied from interface: IntSet

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

Specified by:

union in interface IntSet
