Class DelegatingConnection

java.lang.Object

org.apache.openjpa.lib.jdbc.DelegatingConnection

All Implemented Interfaces:

java.sql.Connection, java.sql.Wrapper, Closeable

Direct Known Subclasses:

ConfiguringConnectionDecorator.ConfiguringConnection, JDBCEventConnectionDecorator.EventConnection, JDBCStoreManager.ClientConnection, JDBCStoreManager.RefCountConnection, LoggingConnectionDecorator.LoggingConnection, PostgresDictionary.PostgresConnection, SybaseDictionary.SybaseConnection

public abstract class DelegatingConnection
extends java.lang.Object
implements java.sql.Connection, Closeable

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