Class CompositeRowKeyReader

java.lang.Object

org.cloudgraph.hbase.key.CompositeRowKeyReader

public class CompositeRowKeyReader
extends Object

Reads and parses row keys into KeyValue elements where the values can then be found using a given Endpoint and used for syntax tree evaluation, for example.

For a collection of row keys, for every key in the collection, a client will read a single row key, then collect its values. Endpoints are created on the first row key and used for all additional keys.

1.0.4
