ArrayBuffer[A]
extends Buffer[A] with ResizableArray[A]Buffer class using an array to
represent the assembled sequence internally.| Values and Variables inherited from ResizableArray | |

| Method Summary | |
override def
|
++:
(iter : Iterable[A]) : Buffer[A]
Prepends a number of elements provided by an iterable object
via its
elements method. The identity of the
buffer is returned. |
override def
|
++=
(iter : Iterable[A]) : Unit
Appends a number of elements provided by an iterable object
via its
elements method. The identity of the
buffer is returned. |
override def
|
++=
(src : Array[A], start : Int, len : Int) : Unit
Appends a number of elements in an array
|
def
|
+:
(elem : A) : Buffer[A]
Prepends a single element to this buffer and return
the identity of the buffer.
|
def
|
+=
(elem : A) : Unit
Appends a single element to this buffer and returns
the identity of the buffer.
|
override def
|
apply
(i : Int) : A
Returns the i-th element of this ArrayBuffer.
|
def
|
clear
: Unit
Clears the buffer contents.
|
override def
|
clone
: Buffer[A]
Return a clone of this buffer.
|
override def
|
equals
(obj : Any) : Boolean
Checks if two buffers are structurally identical.
|
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.
|
protected override def
|
stringPrefix
: String
Defines the prefix of the string representation.
|
def
|
update
(n : Int, newelem : A) : Unit
Replace element at index
n with the new element
newelem. |

| Method Details |
elem - the element to append.elements method. The identity of the
buffer is returned.iter - the iterable object.src - the arraystart - the first element to appendlen - the number of elements to appendelem - the element to append.i - the specified index.Predef.IndexOutOfBoundException - if i is out of bounds.elements method. The identity of the
buffer is returned.iter - the iterable object.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.n - the index where a new element will be inserted.iter - the iterable object providing all elements to insert.n is out of bounds.n with the new element
newelem.n - the index of the element to replace.newelem - the new element.n is out of bounds.n - the index which refers to the element to delete.n is out of bounds.
