Fix Version: Java-Mx
Version: Java-Mx
> Investigate how to best represent 0..n relationships requiring a keyed access
> in models
> ---------------------------------------------------------------------------------------
>
> Key: TUSCANY-182
> URL: http://issues.apache.org/jira/browse/TUSCANY-182
> Project: Tuscany
> Type: Improvement
> Components: Java SDO Implementation
> Versions: Java-Mx
> Reporter: Jean-Sebastien Delfino
> Assignee: Frank Budinsky
> Fix For: Java-Mx
>
> Some of the 0..n relationships in the SCA assembly model should provide a
> keyed access (e.g get a component by name in a composite).
> We need to investigate the best pattern (which we may want to also implement
> in our codegenerator) to provide this function:
> - a list with a get(key) method
> - a map (but the map should preserve the sequence of elements)
> We'll have to balance ease of use for adding to and navigating the
> relationship, ability to implement integrity constraints on the relationship,
> relationship with best model implementation practices as well as the SDO
> spectification, and footprint + performance.
> We also need to investigate if there is a way to automatically derive the
> introduction of this keyed access to a relationship from XSD metadata
> (xsd:key for example).
