org.apache.hadoop.hive.metastore.QueryWrapper

All Implemented Interfaces:

AutoCloseable

public class QueryWrapper
extends Object
implements AutoCloseable

A wrapper around Query objects where the AutoCloseable.close() method is delegated to the wrapped object's Query.closeAll() method. This way the users of the wrapper can use try-with-resources without exception handling.
