Method Summary
override def add (a : A) : Boolean
Adds "a" to the collection, return true if "a" is actually added.
override def addAll (that : Iterable[A]) : Boolean
Adds all elements in "i" to the collection, return true if any elements are added.
override def elements : MutableIterator[A]
The default implementation of a map over mutable iterable collections.
override def equals (that : Any) : Boolean
override def has (a : A) : Boolean
override def hasAll (that : Iterable[A]) : Boolean
Type-safe version of containsAll. * * @author Sean McDirmid
override def hashCode : Int
override def size : Int
Returns the number of elements in this collection.
override def toString : java.lang.String
abstract def underlying : java.util.Collection
Override to specify the collection being accessed through this wrapper. * Collection operations are then routed through the wrapped Java collection.
