Better organization of the interfaces and classes in the SDO Java project
-------------------------------------------------------------------------
Key: TUSCANY-1283
URL: https://issues.apache.org/jira/browse/TUSCANY-1283
Project: Tuscany
Issue Type: Improvement
Components: Java SDO Implementation
Reporter: Frank Budinsky
Fix For: Java-SDO-Mx
Currently, there is no clean separation between client API vs. implementation
(internal) classes. There's also no separation between the EMF-dependent and
independent parts of the RT.
We have been recommending clients stick to standard SDO APIs (from the spec)
and for anything else use class SDOUtil, which is where we put all the required
extensions that people have requested. One other interface, XMLStreamHelper
(for working with StAX streams) is the only other interface in Tuscany that
clients are expected to use directly.
So, clients that are only using standard SDO APIs, SDOUtil, and
XMLStreamHelper, should be unaffected by the reorganization for now, because we
will keep deprecated versions of SDOUtil and XMLStreamHelper around for a
while, but we would like to move them to a better package and have clients
gradually move to the new ones.
Here is the concrete plan:
package org.apache.tuscany.sdo.api (all client API will be under this package)
SDOUtil (new one)
XMLStreamHelper (new one)
other new things ...
package org.apache.tuscany.sdo.rtemf (EMF-based runtime implementation classes)
subset of existing classes (most of them) that have EMF dependencies
(these are existing packages just moved down one level, e.g.,
org.apache.tuscany.sdo.helper -> org.apache.sdo.tuscany.sdo.rtemf.helper)
package org.apache.tuscany.sdo.rtlib (common runtime implementation classes)
subset of existing classes that have no EMF dependencies
package org.apache.tuscany.sdo.util (deprecated)
SDOUtil (deprecated - clients should switch to
org.apache.tuscany.sdo.api.SDOUtil)
package org.apache.tuscany.sdo.helper (deprecated)
XMLStreamHelper (deprecated - clients should switch to
org.apache.tuscany.sdo.api.XMLStreamHelper)
