Package org.apache.cassandra.utils

Class InsertionOrderedNavigableSet<E>

java.lang.Object

org.apache.cassandra.utils.InsertionOrderedNavigableSet<E>

Type Parameters:

E - the type of elements maintained by this set

All Implemented Interfaces:

Iterable<E>, Collection<E>, NavigableSet<E>, Set<E>, SortedSet<E>

public class InsertionOrderedNavigableSet<E>
extends Object
implements NavigableSet<E>

A NavigableSet that enforces in-order insertion of elements. This is helpful when we have an already-ordered collection with no duplicates and want constant time insertion.

Note: Not all methods of NavigableSet are implemented.
