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.
