java.lang.Object

NonLazyKeyValueScanner

org.apache.hadoop.hbase.regionserver.NonReversedNonLazyKeyValueScanner

org.apache.hadoop.hbase.regionserver.SnapshotSegmentScanner

public class SnapshotSegmentScanner
extends NonReversedNonLazyKeyValueScanner

A basic SegmentScanner used against an ImmutableScanner snapshot Used flushing where we do a single pass, no reverse scanning or inserts happening. Its a dumbed-down Scanner that can go fast. Like org.apache.hadoop.hbase.util.CollectionBackedScanner (but making it know about Segments was onerous).
