public Class UnmodifiableArrayList<T>

extends AbstractList<T>
implements RandomAccess
Class Inheritance
All Implemented Interfaces
java.util.RandomAccess
Imports
java.util.AbstractList, .List, .Objects, .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).

list:List<T>

the list, not null

Returns:UnmodifiableArrayList<T>

an unmodifiable list that does not contain null values
