Method Summary
override def ++= (it : Iterator[A]) : Unit
Add all the elements provided by an iterator elems to the set.
override def ++= (that : Iterable[A]) : Unit
Add all the elements provided by an iterator of the iterable object that to the set.
def += (elem : A) : Unit
Add a new element to the set.
override def --= (it : Iterator[A]) : Unit
Remove all the elements provided by an iterator elems from the set.
override def --= (that : Iterable[A]) : Unit
Remove all the elements provided by an iterator of the iterable object elems from the set.
def -= (elem : A) : Unit
Removes a single element from a set.
override def << (cmd : Message[A]) : Unit
Send a message to this scriptable object.
def clear : Unit
Removes all elements from the set. After this operation is completed, the set will be empty.
override def clone : Set[A]
Return a clone of this set.
def contains (elem : A) : Boolean
Checks if this set contains element elem.
override def excl (elems : A*) : Unit
excl removes many elements from the set.
override def foreach (f : (A) => Unit) : Unit
Apply a function f to all elements of this iterable object.
override def incl (elems : A*) : Unit
incl can be used to add many elements to the set at the same time.
override def intersect (that : Set[A]) : Unit
This method computes an intersection with set that. It removes all the elements that are not present in that.
override def isEmpty : Boolean
Checks if this set is empty.
override def retain (p : (A) => Boolean) : Unit
Method retain removes all elements from the set for which the predicate p yields the value false.
def size : Int
Returns the number of elements in this set.
override def subsetOf (that : Set[A]) : Boolean
Checks if this set is a subset of set that.
override def toList : List[A]
Returns a list containing all of the elements in this iterable object.
override def toString : java.lang.String
Returns a string representation of the object.
def update (elem : A, included : Boolean) : Unit
This method allows one to add or remove an element elem from this set depending on the value of parameter included. Typically, one would use the following syntax: 
set(elem) = true

Method Details
def size : Int
Returns the number of elements in this set.
Returns
number of set elements.
override def isEmpty : Boolean
Checks if this set is empty.
Returns
true iff there is no element in the set.
def contains(elem : A) : Boolean
Checks if this set contains element elem.
Parameters
elem - the element to check for membership.
Returns
true iff elem is contained in this set.
def update(elem : A, included : Boolean) : Unit
This method allows one to add or remove an element elem from this set depending on the value of parameter included. Typically, one would use the following syntax: 
set(elem) = true
Overrides
Set.update
def +=(elem : A) : Unit
Add a new element to the set.
Parameters
elem - the element to be added
Overrides
Set.+=
override def ++=(that : Iterable[A]) : Unit
Add all the elements provided by an iterator of the iterable object that to the set.
Parameters
elems - the iterable object containing the elements to be added
Overrides
Set.++=
override def ++=(it : Iterator[A]) : Unit
Add all the elements provided by an iterator elems to the set.
Parameters
elems - the iterator containing the elements to be added
Overrides
Set.++=
override def incl(elems : A*) : Unit
incl can be used to add many elements to the set at the same time.
Deprecated
use ++= instead
Overrides
Set.incl
def -=(elem : A) : Unit
Removes a single element from a set.
Parameters
elem - The element to be removed.
Overrides
Set.-=
override def --=(that : Iterable[A]) : Unit
Remove all the elements provided by an iterator of the iterable object elems from the set.
Overrides
Set.--=
override def --=(it : Iterator[A]) : Unit
Remove all the elements provided by an iterator elems from the set.
Overrides
Set.--=
override def excl(elems : A*) : Unit
excl removes many elements from the set.
Overrides
Set.excl
override def intersect(that : Set[A]) : Unit
This method computes an intersection with set that. It removes all the elements that are not present in that.
Parameters
that - the set to intersect with.
Overrides
Set.intersect
def clear : Unit
Removes all elements from the set. After this operation is completed, the set will be empty.
Overrides
Set.clear
override def subsetOf(that : Set[A]) : Boolean

Parameters
that - another set.
Returns
true iff the other set is a superset of this set. todo: rename to isSubsetOf
override def foreach(f : (A) => Unit) : Unit
Apply a function f to all elements of this iterable object.
Notes
