[jira] Created: (TUSCANY-384) SDOs generated from XSD containing element in complex type result in a getAny() method being created

SDOs generated from XSD containing <any /> element in complex type result in a getAny() method being created
------------------------------------------------------------------------------------------------------------

         Key: TUSCANY-384
         URL: http://issues.apache.org/jira/browse/TUSCANY-384
     Project: Tuscany
        Type: Bug

  Components: Java SDO Tools  
    Versions: Java-M1    
 Environment: Linux (presunme x plaftform)
    Reporter: Dan Murphy


According to spec, one way to generate open content SDOs is to add a <any /> element to the complex type. For example :
<complexType name=[NAME]>
...
<any />
...
</complexType>

Should result in an SDO type:
Type name=[NAME]
open=true
uri=[URI]]
• No property required for
<any>.
• Use getInstanceProperties()
for reflection.
• DataObject and generated
accessors also may be used
to access the value.
• If maxOccurs > 1,
sequenced=true.

And not add anything to the Java interface:
interface [NAME]

(Taken from p88 of SDO spec 2.0.1, Nov 2005)

This does result in an SDO which according to the Type.isOpen() method should be open, but It also generates a getAny() on the interface which is not in line with the specification

Additionally you still don't appeat to be able to add a property by either :
dataObject.set("newProp", "newValue") or
dataObject.getAny().add("newProp", "newValue")

[jira] Resolved: (TUSCANY-384) SDOs generated from XSD containing element in complex type result in a getAny() method being created

["Frank Budinsky (JIRA)" <tu...@ws.apache.org>]

     [ http://issues.apache.org/jira/browse/TUSCANY-384?page=all ]
     
Frank Budinsky resolved TUSCANY-384:
------------------------------------

    Resolution: Invalid

The spec doesn't say that an implementation isn't "allowed" to add the getAny() property, it just says that it isn't "required" to. In Tuscany, we're still thinking about what we will do about this long term, but for now we do generate it, so if you don't need/want it, you should just ignore it (you can also manually delete it from the generated interface if you'd like).

To add open content to an open type you need a global property. In the future we plan to demand create such properties that don't exist already (as in your example), but we currently don't do that. Whether or not an implementation will do that is not clear in the current spec. For now, you need to define the global property (a global element in some schema):

<schema targetNamespace="some-namespace" ...>
    <element name="newProp" type="string">
    ...
</schema>

You can alternatively (instead of in a schema) use SDOUtil to define the global property dynamically something like this:

    Type globalType = SDOUtil.createType(TypeHelper.INSTANCE, "some-namespace", null, false); // create a holder type for global properties (name must be null)
    SDOUtil.createProperty(globalType, "newProp", TypeHelper.INSTANCE.getType("commonj.sdo", "String");

In SDO 2.1, there will be an easier way to do this - a new method: TypeHelper.defineGlobalProperty().

Then you can set the property in your open object like this:

dataObject.set(XSDHelper.INSTANCE.getGlobalProperty("some-namespace", "newProp", true), "newValue")

Also, like I said above, in the future you will also be able to just do this:

dataObject.set("newProp", "newValue")

and the implementation will do something like this under the covers (if newProp is not already created):

    Type globalType = SDOUtil.createType(TypeHelper.INSTANCE, dataObject.getType().getURI(), null, false); // if not already created
    Property prop = SDOUtil.createProperty(globalType, "newProp", TypeHelper.INSANCE.getType(newValue.getClass());
    dataObject.set(prop, newValue);
