Class UnmodifiableArrayList<E>

  • Type Parameters:
    E - Element type
    All Implemented Interfaces:
    java.lang.Iterable<E>, java.util.Collection<E>, java.util.List<E>, java.util.RandomAccess

    public class UnmodifiableArrayList<E>
    extends java.util.AbstractList<E>
    implements java.util.RandomAccess
    A view onto an array that cannot be modified by the client.

    Since the array is not copied, modifications to the array will be reflected in the list.

    Null elements are allowed.

    Quick and low-memory, like Arrays.asList(Object[]), but unmodifiable.
