RandomAccessSeq[A]Method Summary | |
override def
|
drop
(from : Int) : MutableProjection[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
|
projection
: MutableProjection[A]
returns a projection that can be used to call non-strict
filter ,
map , and flatMap methods that build projections
of the collection. |

readOnly : RandomAccessSeq[A] |
override def
|
reverse
: MutableProjection[A]
A sequence consisting of all elements of this sequence in reverse order.

slice
(from0 : Int, until0 : Int) : MutableProjection[A]
A sub-sequence of
len elements
starting at index from (non-strict) |
override def
|
take
(until : Int) : MutableProjection[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) |

for xs.update(i, x)
