public interface ClusteringPrefix extends IMeasurableMemory, Clusterable
ClusteringComparator can compare.
 It holds values for the clustering columns of a table (potentially only a prefix of all of them) and has a "kind" that allows us to implement slices with inclusive and exclusive bounds.
 In practice, ClusteringPrefix is just the common parts to its 3 main subtype: Clustering and
 ClusteringBound/ClusteringBoundary, where:
   1) Clustering represents the clustering values for a row, i.e. the values for it's clustering columns.
   2) ClusteringBound represents a bound (start or end) of a slice (of rows) or a range tombstone.
   3) ClusteringBoundary represents the threshold between two adjacent range tombstones.
 See those classes for more details.

| Modifier and Type | Method and Description | 
|---|---|
| int | dataSize()The size of the data hold by this prefix. | 
| void | digest(java.security.MessageDigest digest)Adds the data of this clustering prefix to the provided digest. | 
| java.nio.ByteBuffer | get(int i)Retrieves the ith value of this prefix. | 
| java.nio.ByteBuffer[] | getRawValues()The values of this prefix as an array. | 
| ClusteringPrefix.Kind | kind() | 
| int | size()The number of values in this prefix. | 
| java.lang.String | toString(CFMetaData metadata)Generates a proper string representation of the prefix. |

 Please note that this may or may not require an array creation. So 1) you should *not*
 modify the returned array and 2) it's more efficient to use size() and
 get(int) unless you actually need an array.
