class RefBuffer
[source: scala/swing/RefBuffer.scala]
abstract class RefBuffer[A <: AnyRef]
extends Buffer[A] with scala.swing.SingleRefCollection[A]
Value Summary
protected abstract val underlying : Buffer[Reference[A]]
Values and Variables inherited from scala.swing.SingleRefCollection
scala.swing.SingleRefCollection.referenceQueue
Method Summary
def +: (el : A) : RefBuffer[A]
Prepend a single element to this buffer and return the identity of the buffer.
def += (el : A) : Unit
Append a single element to this buffer.
def apply (n : Int) : A
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 length : Int
Returns the length of the sequence.
def readOnly : Seq[A]
return a read only alias of this buffer
def remove (el : A) : Unit
def remove (n : Int) : A
Removes the element on a given index position.
protected[this] def removeReference (ref : Reference[A]) : Unit
def update (n : Int, el : A) : Unit
Replace element at index n with the new element newelem.

Method Details
def +=(el : A) : Unit
Append a single element to this buffer.
Parameters
elem - the element to append.
Overrides
Buffer.+=
def +:(el : A) : RefBuffer[A]
Prepend a single element to this buffer and return the identity of the buffer.
Parameters
elem - the element to append.
Overrides
Buffer.+:
def remove(el : A) : Unit
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 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, el : 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 readOnly : Seq[A]
return a read only alias of this buffer
Overrides
Buffer.readOnly
def apply(n : Int) : A
def length : Int
Returns the length of the sequence.
Returns
the sequence length.
def clear : Unit
Clears the buffer contents.
Overrides
Buffer.clear
