Method Summary

Modifier and Type	Method	Description
void	add(Set<T> s)	Adds to this all elements of s that are not already in this, also removing just those elements from s.
boolean	isSubset(Set<T> s)	Reports whether this is a subset of s.
Set<T>	remove(Set<T> s)	Removes from this all elements of s that are also in this, leaving s unchanged, and returns the elements actually removed.

Method Details

add

void add(Set<T> s)

Adds to this all elements of s that are not already in this, also removing just those elements from s.

Parameters:

s - the Set whose elements are to be added to this

Updates:

this, s

Ensures:

this = #this union #s  and
s = #this intersection #s

remove

Set<T> remove(Set<T> s)

Removes from this all elements of s that are also in this, leaving s unchanged, and returns the elements actually removed.

Parameters:

s - the Set whose elements are to be removed from this

Returns:

the Set whose elements actually were removed from this

Updates:

this

Ensures:

this = #this \ s  and
remove = #this intersection s

isSubset

boolean isSubset(Set<T> s)

Reports whether this is a subset of s.

Parameters:

s - the second set

Returns:

whether this is a subset of s

Ensures:

isSubset = this is subset of s
