[source: scala/collection/mutable/ObservableBuffer.scala]

trait ObservableBuffer[A, This <: ObservableBuffer[A, This]]
extends Buffer[A] with Publisher[Message[(Location, A)] with Undoable, This]

Method Summary
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.

Method Details
def +(element : A) : Buffer[A]
Append a single element to this buffer and return the identity of the buffer.
Parameters
elem - the element to append.
Overrides
Buffer.+

def +:(element : A) : Buffer[A]
Prepend a single element to this buffer and return the identity of the buffer.
Parameters
elem - the element to append.
Overrides
Buffer.+:

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.
Parameters
n - the index where a new element will be inserted.
iter - the iterable object providing all elements to insert.
Overrides
Buffer.insertAll

def update(n : Int, newelement : A) : Unit
Replace element at index n with the new element newelem.
Parameters
n - the index of the element to replace.
newelem - the new element.
Overrides
Buffer.update

def remove(n : Int) : A
Removes the element on a given index position.
Parameters
n - the index which refers to the element to delete.
Overrides
Buffer.remove

def clear : Unit
Clears the buffer contents.
Overrides
Buffer.clear
