Class ImmutableAppendedList<T>

java.lang.Object
  org.modeshape.common.collection.ImmutableAppendedList<T>

Type Parameters:

T - the type of element

All Implemented Interfaces:

Iterable<T>, Collection<T>, List<T>

@Immutable
public class ImmutableAppendedList<T>
extends Object
implements List<T>

An immutable List that consists of a single element appended to another existing List. The result is a list that contains all of the elements in the parent list as well as the last appended element, but while reusing the existing parent list and without having to create a copy of the parent list.

Constructor Summary

ImmutableAppendedList(List<T> parent, T element)
Create an instance using the supplied parent list and an element to be virtually appended to the parent.

Constructor Detail

ImmutableAppendedList

public ImmutableAppendedList(List<T> parent,
