trait ObservableBuffer

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

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

  This class is typically used as a mixin. It adds a subscription mechanism to the `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`.

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
