Package org.apache.openjpa.lib.jdbc

Class DelegatingStatement

java.lang.Object

org.apache.openjpa.lib.jdbc.DelegatingStatement

All Implemented Interfaces:

java.lang.AutoCloseable, java.sql.Statement, java.sql.Wrapper, Closeable

Direct Known Subclasses:

LoggingConnectionDecorator.LoggingConnection.LoggingStatement

public class DelegatingStatement
extends java.lang.Object
implements java.sql.Statement, Closeable

Wrapper around an existing statement. Subclasses can override the methods whose behavior they mean to change. The equals and hashCode methods pass through to the base underlying data store statement.
