Constructor Detail

JdbcConnectionWrapper

protected JdbcConnectionWrapper(ConnectionDescriptor descriptor,
                                ConnectInfoPrompter prompter,
                                ConnectionManager manager)
                         throws CMException

package access constructor. Only ConnectionManager should instantiate this class. ConnectionWrapper relies on the ConnectionManager knowing about it.

Parameters:

descriptor - the ConnectionDescriptor to use to instantiate the connection.

prompter - a ConnectInfoPrompter to use to get the user connection information.

manager - the ConnectionManager which is responsible for managing this connection.

Throws:

CMException - occurs if there is a problem registering and/or finding the JDBC driver specified in the descriptor.
