class JSetWrapper
[source: scala/collection/JavaConversions.scala]
case class JSetWrapper[A](val underlying : java.util.Set[A])
extends Set[A] with MutableSetTemplate[A, JSetWrapper[A]] with Product
Method Summary
def += (elem : A) : JSetWrapper[A]
Adds a new element to the set.
def -= (elem : A) : JSetWrapper[A]
Removes a single element from a set.
override def add (elem : A) : Boolean
Adds a new element to the set.
override def canEqual (arg0 : Any) : Boolean
An equality helper method to assist in maintaining reflexivity in the face of subtyping. For more, see http://www.artima.com/lejava/articles/equality.html
override def clear : Unit
Removes all elements from the set. After this operation is completed, the set will be empty.
def contains (elem : A) : Boolean
Checks if this set contains element elem.
override def empty : JSetWrapper[A]
def iterator : Iterator[A]
Creates a new iterator over all elements contained in this iterable object.
override def productArity : Int
return k for a product A(x_1,...,x_k)
override def productElement (arg0 : Int) : Any
for a product A(x_1,...,x_k), returns x_(n+1) for 0 <= n < k
override def productPrefix : java.lang.String
By default the empty string. Implementations may override this method in order to prepend a string prefix to the result of the toString methods.
override def remove (elem : A) : Boolean
Removes a single element from a set.
override def size : Int
The number of elements in this collection

Method Details
override def size : Int
The number of elements in this collection
def iterator : Iterator[A]
Creates a new iterator over all elements contained in this iterable object.
Returns
the new iterator
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 +=(elem : A) : JSetWrapper[A]
Adds a new element to the set.
Parameters
elem - the element to be added
Overrides
MutableSetTemplate.+=
def -=(elem : A) : JSetWrapper[A]
Removes a single element from a set.
Parameters
elem - The element to be removed.
Overrides
MutableSetTemplate.-=
override def add(elem : A) : Boolean
Adds a new element to the set.
Parameters
elem - the element to be added
Returns
true if the element was not yet present in the set.
Overrides
MutableSetTemplate.add
override def remove(elem : A) : Boolean
Removes a single element from a set.
Parameters
elem - The element to be removed.
Returns
true if the element was already present in the set.
Overrides
MutableSetTemplate.remove
override def clear : Unit
Removes all elements from the set. After this operation is completed, the set will be empty.
Overrides
MutableSetTemplate.clear
override def empty : JSetWrapper[A]
override def productPrefix : java.lang.String
