Method Summary | |
def
|
+:
(el : A) : RefBuffer[A]
Prepend a single element to this buffer and return
the identity of the buffer.
|
def
|
+=
(el : A) : Unit
Append a single element to this buffer.
|
def
|
apply (n : Int) : A |
def
|
clear
: Unit
Clears the buffer contents.
|
def
|
insertAll
(n : Int, iter : Iterable[A]) : Unit
Inserts new elements at the index
n . Opposed to method
update , this method will not replace an element with a
one. Instead, it will insert a new element at index n . |
def
|
length
: Int
Returns the length of the sequence.
|
def
|
readOnly
: Seq[A]
return a read only alias of this buffer
|
def
|
remove
(n : Int) : A
Removes the element on a given index position.
|
def
|
remove (el : A) : Unit |
protected[this] def
|
removeReference (ref : Reference[A]) : Unit |
def
|
update
(n : Int, el : A) : Unit
Replace element at index
n with the new element
newelem . |
