Method Details
def +=(el : A) : RefBuffer[A]
Append a single element to this buffer.
Parameters
elem - the element to append.
def +=:(el : A) : RefBuffer[A]
Prepend a single element to this buffer and return the identity of the buffer.
Parameters
elem - the element to prepend.
def remove(el : A) : Unit
def remove(n : Int) : A
