Class CassandraThriftKeyColumnValueStore.AbstractBufferedRowIter<T extends org.apache.cassandra.dht.Token<?>>

java.lang.Object

com.thinkaurelius.titan.diskstorage.cassandra.thrift.CassandraThriftKeyColumnValueStore.AbstractBufferedRowIter<T>

All Implemented Interfaces:

KeyIterator, RecordIterator<StaticBuffer>, Closeable, AutoCloseable, Iterator<StaticBuffer>

Enclosing class:

CassandraThriftKeyColumnValueStore

public class CassandraThriftKeyColumnValueStore.AbstractBufferedRowIter<T extends org.apache.cassandra.dht.Token<?>>
extends Object
implements KeyIterator

Slices rows and columns using tokens. Recall that the partitioner turns keys into tokens. For instance, under RandomPartitioner, tokens are the MD5 hashes of keys.
