Method Summary
`override def`	clear : Unit clear all elements from the collection.
`override def`	elements : MutableIterator[A] The default implementation of a map over mutable iterable collections.

`override def`	removeAll (that : Iterable[A]) : Boolean
`override def`	retainAll (that : Iterable[A]) : Boolean retain only elements that are also in that.
`override def`	size : Int Returns the number of elements in this collection.
`abstract def`	underlying : java.util.Collection[A]
