## Class MerkleTree.TreeRange

- java.lang.Object
- - org.apache.cassandra.dht.AbstractBounds<T>
  - - org.apache.cassandra.dht.Range<Token>
    - - org.apache.cassandra.utils.MerkleTree.TreeRange

- All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<Range<Token>>
  Direct Known Subclasses:
    MerkleTree.TreeDifference
  Enclosing class:
    MerkleTree

      public static class MerkleTree.TreeRange
      extends Range<Token>

  The public interface to a range in the tree. NB: A TreeRange should not be returned by a public method unless the parents of the range it represents are already invalidated, since it will allow someone to modify the hash. Alternatively, a TreeRange may be created with a null tree, indicating that it is read only.
