Class SSTableSimpleIterator

java.lang.Object

org.apache.cassandra.utils.AbstractIterator<Unfiltered>

org.apache.cassandra.io.sstable.SSTableSimpleIterator

All Implemented Interfaces:

com.google.common.collect.PeekingIterator<Unfiltered>, java.lang.AutoCloseable, java.util.Iterator<Unfiltered>, CloseableIterator<Unfiltered>

Direct Known Subclasses:

SSTableSimpleIterator.EmptySSTableSimpleIterator

public abstract class SSTableSimpleIterator
extends AbstractIterator<Unfiltered>
implements java.util.Iterator<Unfiltered>

Utility class to handle deserializing atom from sstables.

Note that this is not a full fledged UnfilteredRowIterator. It's also not closeable, it is always the job of the user to close the underlying ressources.
