trait SetProxy

[source: scala/collection/mutable/SetProxy.scala]

trait SetProxy[A]
extends Set[A] with SetProxy[A]
This is a simple wrapper class for scala.collection.mutable.Set. It is most useful for assembling customized set abstractions dynamically using object composition and forwarding.

Method Summary
override def ++= (that : Iterable[A]) : Unit
Add all the elements provided by an iterator of the iterable object that to the set.
override def ++= (it : Iterator[A]) : Unit
Add all the elements provided by an iterator elems to the set.
def += (elem : A) : Unit
Add a new element to the set.
override def --= (that : Iterable[A]) : Unit
Remove all the elements provided by an iterator of the iterable object elems from the set.
override def --= (it : Iterator[A]) : Unit
Remove all the elements provided by an iterator 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.
override 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.
override def excl (elems : A*) : Unit
excl removes many elements from the set.
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 retain (p : (A) => Boolean) : Unit
Method retain removes all elements from the set for which the predicate p yields the value false.
abstract def self : Set[A]
override 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
