Class UnmodifiableArrayList<T>

java.lang.Object

java.util.AbstractList<T>

com.sun.javafx.UnmodifiableArrayList<T>

All Implemented Interfaces:

java.lang.Iterable<T>, java.util.Collection<T>, java.util.List<T>, java.util.RandomAccess

public class UnmodifiableArrayList<T>
extends java.util.AbstractList<T>
implements java.util.RandomAccess

An unmodifiable array-based List implementation. This is essentially like the package private UnmodifiableRandomAccessList of the JDK, and helps us to avoid having to do a lot of conversion work when we want to pass an array into an unmodifiable list implementation (otherwise we would have to create a temporary list that is then passed to Collections.unmodifiableList).
