Class DelegatingConnection

java.lang.Object
  org.apache.openjpa.lib.jdbc.DelegatingConnection

All Implemented Interfaces:

Connection, Closeable

Direct Known Subclasses:

JDBCStoreManager.RefCountConnection

public class DelegatingConnection
extends Object
implements 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.
