[jira] Created: (TUSCANY-1197) Sequence composition
Sequence composition
--------------------
Key: TUSCANY-1197
URL: https://issues.apache.org/jira/browse/TUSCANY-1197
Project: Tuscany
Issue Type: New Feature
Components: Java SDO Implementation
Affects Versions: Java-SDO-Mx
Reporter: Yang ZHONG
Fix For: Java-SDO-Mx
DataObject#getSequence() provides one single Sequence for users to access properties.
However, a DataObject can have more than one non-derived Sequences.
The attached prototype enables DataObject#getSequence() to return a Sequence composition aggregating multiple non-derived Sequences.

[jira] Commented: (TUSCANY-1197) Sequence composition

Frank Budinsky commented on TUSCANY-1197:
-----------------------------------------
The attached class Sequences is a good start (a better name would be VirtualSequence), but has some problems. It needs to filter derived fetures, so they don't result in duplicates. Also if all properties are derived from a single featureMap (e.g., mixed), it can servie as the composed Sequence. The test case should not be accessing hidden properties (like choice, any, etc.), it shoud just confirm that the composed Sequence() contains the right properties in the right positions.

Yang ZHONG commented on TUSCANY-1197:
-------------------------------------
Derived fetures have already been filtered out by the patched ClassImpl, search getSequenceFeature() & isSequenceFeatureMap for isDerived().
Therefore, cases such as mixed are already taken care of.

-----------------------------------------
Thanks Yang, I missed that.
I found the getSequenceFeature() method hard to follow. I don't think it's quite right and will need some more work.
