Class ConcatenatedLists<T>

java.lang.Object
  org.apache.hadoop.hbase.util.ConcatenatedLists<T>

All Implemented Interfaces:

Iterable<T>, Collection<T>

public class ConcatenatedLists<T>
extends Object
implements Collection<T>

A collection class that contains multiple sub-lists, which allows us to not copy lists. This class does not support modification. The derived classes that add modifications are not thread-safe. NOTE: Doesn't implement list as it is not necessary for current usage, feel free to add.
