Hasan Muhammad commented on TUSCANY-709:
----------------------------------------
Yang,
Yes i meant using EXTENDED_META_DATA as a string. But if the
XMLResource.OPTION_EXTENDED_META_DATA is a pointer, then it should be fine.
Kelvin,
Can we have this reviewed and committed soon please. We need this.
Thanks
Hasan
> Loads DataGraph in designated scope(TypeHelper)

> Key: TUSCANY-709
> URL: https://issues.apache.org/jira/browse/TUSCANY-709
> Project: Tuscany
> Issue Type: Improvement
> Components: Java SDO Implementation
> Affects Versions: Java-M2
> Reporter: Yang ZHONG
> Priority: Minor
> Fix For: Java-SDO-Mx
>
> Attachments: patch.709

>
> SDOUtil.loadDataGraph doesn't support scope, this improvement tries to
> address that.
> TypeHelper#define registers Types with the corresponding TypeHelper instance
> (scope)
> and XMLHelper#load utilizes the registered Types from the corresponding scope
> to instantiate DataObject instances.
> Unfortunately yet, current SDOUtil.loadDataGraph
> 2-1. can't designate scope to register serialized Types,
> 2-2. and can't designate scope to utilize already registered Types in order
> to instantiate user expected DataObject instances.
> An example of 2-1 is SerializeTypesTestCase had to
> // The following is a kludge to force deserialization of metadata
> into a different TypeHelper (scope)
> // TBD figure out a proper non-EMF way to do this.
> Map options = new HashMap();
> Object differentFromSerializing = ((TypeHelperImpl)
> deserializingTypeHelper).getExtendedMetaData();
> options.put(XMLResource.OPTION_EXTENDED_META_DATA,
> differentFromSerializing);
> This proposal tries to adress scope by
> 2-1. add new SDOUtil.loadDataGraph(InputStream inputStream,Map
> options,TypeHelper scope)throws IOException
> 2-2. deprecate old SDOUtil.loadDataGraph(InputStream inputStream,Map
> options)throws IOException
> Any comment is welcomed.
