Method Summary
override def ++ [B >: A](that : Iterable[B]) : RandomAccessSeq[B]
Appends two iterable objects.
override def drop (from : Int) : RandomAccessSeq[A]
Returns this sequence without its n first elements If this sequence has less than n elements, the empty sequence is returned. (non-strict)
override def elements : Iterator[A]
Creates a new iterator over all elements contained in this object.
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.
override def reverse : Seq[A]
A sequence consisting of all elements of this sequence in reverse order.
final def safeIs (idx : Int, a : Any) : Boolean
will return false if index is out of bounds
override def slice (from : Int, until : Int) : RandomAccessSeq[A]
A sub-sequence of len elements starting at index from (non-strict)
override def take (until : Int) : RandomAccessSeq[A]
Returns a sequence consisting only over the first n elements of this sequence, or else the whole sequence, if it has less than n elements. (non-strict)
override def toStream : Stream[A]
Create a stream which contains all the elements of this iterable object.
