Direct Known Subclasses:
Buffer, MutableSeq.Projection

Method Summary
override def apply (idx : Int) : A
override def elements : SeqIterator[Int, A]
The default implementation of a map over mutable iterable collections.
def indexOf (a : A) : Option[Int]
Find the index of "a" in this sequence.
override def isEmpty : Boolean
Returns true if length == 0
override def length : Int
Returns the length of the sequence.
override def projection : Projection[A]
returns a projection that can be used to call non-strict filter, map, and flatMap methods that build projections of the collection.
