Class UnmodifiableList<E>

java.lang.Object
  extended by com.liferay.portal.kernel.util.UnmodifiableList<E>
All Implemented Interfaces:
Serializable, Iterable<E>, Collection<E>, List<E>

public class UnmodifiableList<E>
extends Object
implements List<E>, Serializable

This is a read-only wrapper around any java.util.List. Query operations will "read through" to the specified list. Attempts to modify the list directly or via its iterator will result in a java.lang.UnsupportedOperationException.
