Method Summary
`def` | += (elem : A) : Unit Add a new element to the set.
`def` | -= (elem : A) : Unit Removes a single element from a set.
`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.
`def` | contains (elem : A) : Boolean Checks if this set contains element `elem`.
`def` | elements : Iterator[A] Creates a new iterator over all elements contained in this object.
`override def` | isEmpty : Boolean Checks if this set is empty.
`def` | size : Int Returns the number of elements in this set.

Parameters
  `elem -` the element to check for membership.
Returns
  `true` iff `elem` is contained in this set.

`` `def` elements : Iterator[A]

  Creates a new iterator over all elements contained in this object.

Returns
  the new iterator

`` `def` +=(elem : A) : Unit

  Add a new element to the set.

Parameters

Overrides
  Set.+=

`` `def` -=(elem : A) : Unit

  Removes a single element from a set.

Parameters
