Class KeyRange

java.lang.Object
  org.apache.cassandra.thrift.KeyRange

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.lang.Comparable<KeyRange>, org.apache.thrift.TBase<KeyRange,KeyRange._Fields>

public class KeyRange
extends java.lang.Object
implements org.apache.thrift.TBase<KeyRange,KeyRange._Fields>, java.io.Serializable, java.lang.Cloneable

The semantics of start keys and tokens are slightly different. Keys are start-inclusive; tokens are start-exclusive. Token ranges may also wrap -- that is, the end token may be less than the start one. Thus, a range from keyX to keyX is a one-element range, but a range from tokenY to tokenY is the full ring.
