E - the type of elements in this listpublic final class ListIndexProxy<E> extends AbstractNativeProxy implements ListIndex<E>
This list implementation does not permit null elements.
The "destructive" methods of the list, i.e., those that change its contents,
are specified to throw UnsupportedOperationException if
this list has been created with a read-only database view.
All method arguments are non-null by default.
This class is not thread-safe and and its instances shall not be shared between threads.
When the view goes out of scope, this list is destroyed. Subsequent use of the closed list
is prohibited and will result in IllegalStateException.
