Class CellValues

java.lang.Object

org.cloudgraph.hbase.io.CellValues

public class CellValues
extends Object

Local column qualifier/value map which is mutable such that column results can be incrementally added. Intended for read operations not write as cell versions are not accounted for. This class is not thread safe, use it in a single threaded context only.

While the HBase client Result structure is great and extremely flexible, it is not something we want to incrementally add qualifiers, values to during repeated read operations, and not something we can create from data in memory.
