trait
ObservableBuffer[A, This <: ObservableBuffer[A, This]]
extends
Buffer[A] with
Publisher[Message[(Location, A)] with
Undoable, This]Buffer
class into which this abstract
class is mixed in. Class ObservableBuffer
publishes
events of the type Message
.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 . |
