public class ListBuffer<A>
extends java.util.AbstractQueue<A>

A class for constructing lists by appending elements. Modelled after java.lang.StringBuffer.

This is NOT part of any API supported by Sun Microsystems. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice.

Field Summary

int	count The number of element in this buffer.
List<A>	elems The list of elements of this buffer.
List<A>	last A pointer pointing to the last, sentinel element of `elems'.
boolean	shared Has a list been created from this buffer yet?

Constructor Summary

ListBuffer()
Create a new initially empty list buffer.

ListBuffer<A>	appendList(List<A> xs) Append all elements in a list to buffer.
ListBuffer<A>	appendList(ListBuffer<A> xs) Append all elements in a list to buffer.
void	clear()
boolean	contains(java.lang.Object x) Does the list contain the specified element?
boolean	containsAll(java.util.Collection<?> c)
private void	copy() Copy list and sets last.
A	first() The first element in this buffer.
boolean	isEmpty() Is buffer empty?
java.util.Iterator<A>	iterator() An enumeration of all elements in this buffer.
static <T> ListBuffer<T>	lb()
int	length() Return the number of elements in this buffer.
