Examples of EngineConnection

org.apache.derby.iapi.jdbc.EngineConnection
Additional methods the embedded engine exposes on its Connection object implementations. An internal api only, mainly for the network server. Allows consistent interaction between EmbedConnections and BrokeredConnections.

Examples of org.apache.derby.iapi.jdbc.EngineConnection

        if (password != null) 
        p.put(Attribute.PASSWORD_ATTR, password);
                
        // Contract between network server and embedded engine
        // is that any connection returned implements EngineConnection.
        EngineConnection conn = (EngineConnection)
