def + (element : A) : Buffer[A]
Append a single element to this buffer and return the identity of the buffer.
def +: (element : A) : Buffer[A]
Prepend a single element to this buffer and return the identity of the buffer.
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 remove (n : Int) : A
Removes the element on a given index position.
def update (n : Int, newelement : A) : Unit
Replace element at index n with the new element newelem.
