Method Summary
override def + (elem : A) : Buffer
Append a single element to this buffer and return the identity of the buffer.
override def ++ (iter : Traversable[A]) : Buffer
Appends a number of elements provided by an iterable object via its iterator method. The identity of the buffer is returned.
override def ++= (iter : Traversable[A]) : SynchronizedBuffer[A]
Appends a number of elements provided by an iterable object via its iterator method.
override def ++=: (iter : Traversable[A]) : SynchronizedBuffer[A]
Prepends a number of elements provided by an iterable object via its iterator method. The identity of the buffer is returned.
def += (elem : A) : SynchronizedBuffer[A]
Append a single element to this buffer.
def +=: (elem : A) : SynchronizedBuffer[A]
Prepend a single element to this buffer and return the identity of the buffer.
override def << (cmd : Message[A]) : Unit
Send a message to this scriptable object.
override def append (elems : A*) : Unit
Appends a sequence of elements to this buffer.
override def appendAll (iter : Traversable[A]) : Unit
Appends a number of elements provided by an iterable object via its iterator method.
def apply (n : Int) : A
Return element at index `n`
def clear : Unit
Clears the buffer contents.
override def clone : Buffer
Return a clone of this buffer.
override def hashCode : Int
The hashCode method always yields an error, since it is not safe to use buffers as keys in hash tables.
override def insert (n : Int, elems : 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 the new elements at index n.
def insertAll (n : Int, iter : Traversable[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 iterator : Iterator[A]
Creates a new iterator over all elements contained in this iterable object.
def length : Int
Return number of elements in the buffer
override def prepend (elems : A*) : Unit
Prepend an element to this list.
override def prependAll (elems : Traversable[A]) : Unit
Prepends a number of elements provided by an iterable object via its iterator method. The identity of the buffer is returned.
def remove (n : Int) : A
Removes the element on a given index position.
def update (n : Int, newelem : A) : Unit
Replace element at index n with the new element newelem.

Method Details
def length : Int
Return number of elements in the buffer
def iterator : Iterator[A]
Creates a new iterator over all elements contained in this iterable object.
Returns
the new iterator
def apply(n : Int) : A
Return element at index `n`
Throws
IndexOutofBoundsException - if the index is not valid
override def +(elem : A) : Buffer
Append a single element to this buffer and return the identity of the buffer.
Parameters
elem - the element to append.
def +=(elem : A) : SynchronizedBuffer[A]
Append a single element to this buffer.
Parameters
elem - the element to append.
override def ++(iter : Traversable[A]) : Buffer
Appends a number of elements provided by an iterable object via its iterator method. The identity of the buffer is returned.
Parameters
iter - the iterable object.
override def ++=(iter : Traversable[A]) : SynchronizedBuffer[A]
Appends a number of elements provided by an iterable object via its iterator method.
Parameters
iter - the iterable object.
override def append(elems : A*) : Unit
Appends a sequence of elements to this buffer.
Parameters
elems - the elements to append.
override def appendAll(iter : Traversable[A]) : Unit
Appends a number of elements provided by an iterable object via its iterator method.
Parameters
iter - the iterable object.
def +=:(elem : A) : SynchronizedBuffer[A]
Prepend a single element to this buffer and return the identity of the buffer.
Parameters
elem - the element to append.
override def ++=:(iter : Traversable[A]) : SynchronizedBuffer[A]
Prepends a number of elements provided by an iterable object via its iterator method. The identity of the buffer is returned.

Parameters
n - the index where a new element will be inserted.
elems - the new elements to insert.
def insertAll(n : Int, iter : Traversable[A]) : Unit
