Class CellSet

java.lang.Object

org.apache.hadoop.hbase.regionserver.CellSet

All Implemented Interfaces:

java.lang.Iterable<Cell>, java.util.Collection<Cell>, java.util.NavigableSet<Cell>, java.util.Set<Cell>, java.util.SortedSet<Cell>

public class CellSet
extends java.lang.Object
implements java.util.NavigableSet<Cell>

A Set of Cells, where an add will overwrite the entry if already exists in the set. The call to add returns true if no value in the backing map or false if there was an entry with same key (though value may be different). implementation is tolerant of concurrent get and set and won't throw ConcurrentModificationException when iterating.
