ArrayLike[A]Method Summary  
override def

drop
(from : Int) : Projection[A]
Returns this sequence without its
n first elements
If this sequence has less than n elements, the empty
sequence is returned. (nonstrict) 
override def

dropWhile
(p : (A) => Boolean) : Projection[A]
Returns the longest suffix of this sequence whose first element
does not satisfy the predicate
p . 
override def

force : Array[A] 
override def

projection
: Projection[A]
returns a projection that can be used to call nonstrict
filter ,
map , and flatMap methods that build projections
of the collection. 
override def

reverse
: Projection[A]
A sequence consisting of all elements of this sequence in reverse order.

override def

slice
(from : Int, until : Int) : Projection[A]
A subsequence of
len elements
starting at index from (nonstrict) 
override def

take
(until : Int) : Projection[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. (nonstrict) 
override def

takeWhile
(p : (A) => Boolean) : Projection[A]
Returns the longest prefix of this sequence whose elements satisfy
the predicate
p .

def
take(until : Int) : Projection[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. (nonstrict)

Parameters
n 
the number of elements to take
Returns
 a possibly projected sequence

elements, the empty
sequence is returned. (nonstrict)

Parameters
n

Returns
 the new sequence

override
def
dropWhile(p : (A) => Boolean) : Projection[A]
 Returns the longest suffix of this sequence whose first element
does not satisfy the predicate
p

p
.

override
