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 : String
`abstract def` | underlying : Collection Override to specify the collection being accessed through this wrapper. * Collection operations are then routed through the wrapped Java collection.
