Class StatObjectConverter

java.lang.Object

org.apache.hadoop.hive.metastore.StatObjectConverter

public class StatObjectConverter
extends Object

This class contains conversion logic that creates Thrift stat objects from JDO stat objects and plain arrays from DirectSQL. It is hidden here so that we wouldn't have to look at it in elsewhere.
