Description copied from interface: FarragoMedDataWrapper

Creates an instance of this wrapper for a particular server. This supports the SQL/MED CREATE SERVER statement. The TYPE and VERSION attributes are rolled in with the other properties. As much validation as possible should be performed, including establishing connections if appropriate.

serverMofId - MOFID of server definition in repository; this can be used for accessing the server definition from generated code

props - server properties

Returns:

new server instance

Throws:

SQLException - if server connection is unsuccessful

Specified by:

Returns:

true for foreign data; false for local data
